This gem yourub is not compatible with fetching particular page of the result set(pagination)
Is there any other way to fetch data sets of the Youtube result searcged by a query?
I'd like to select the page number of the result set, and the maximum number of the records to show in one query.
I have a Deal model with a column/attribute called 'deal_info' which is a json column.
It looks like this for example
deal1.deal_info = [ { "modal_id": "4", "text1":"lorem" },
{ "modal_id": "6", "video2":"yonak" },
{ "modal_id": "9", "video2":"boom" } ]
deal2.deal_info = [ { "modal_id": "10", "text1":"lorem" },
{ "modal_id": "11", "video2":"yonak" },
{ "modal_id": "11", "image4":"boom" } ]
On my view deal.html.erb, i have:
<%= for deal_nb in 0..@deal.number_of_deals do %>
<div class="modal fade" id="myInfoModal<%= modal_nb %>" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<!-- render the right modal type -->
<%= render "layouts/modal_type_partials/mt#{ @deal.deal_info[deal_nb]['modal_id'] }", parameter_i_want_to_pass: deal_nb %>
</div>
<% end %>
Above, as you see above, I'd like to pass for each iteration of the loop inside parameter_i_want_to_pass the number of the iteration loop (2nd iteration would be parameter_i_want_to_pass= 2 for example).
On the partial I have:
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">this is mt4</h4>
</div>
<div class="modal-body">
this is the text: <%= @deal.deal_info[parameter_i_want_to_pass]['text1'] %>
</div>
</div>
I get the following error:
no implicit conversion of String into Integer (on line "this is the text: <%= @deal.deal_info[parameter_i_want_to_pass]")
Actually I even tried to detect more easily the bug by just passing a set number instead of the variable 'deal_nb'
<%= render "layouts/modal_type_partials/mt#{ @deal.deal_info[deal_nb]['modal_id'] }", parameter_i_want_to_pass: 2 %>
But I still get exactly the same error.
I am using foreman gem on my Rails project to handle the different processes to be launched at startup (web, mailer, delayed job, ...).
It's working as expected but if I save a file with a typo or try to access a property on a nil object, foreman crash for all processes. I have to manually kill each ruby and node (for maildev) processes in order to run foreman start again.
Is there a way to prevent foreman to crash as the plumber plugin for gulp tasks ?
Thanks !

I use cancancan gem for role based authorization rules. I need to preform something like:
can :read, Post, Post.status = 1
This means that user can read post with status = 1. How can i do that?
I'm trying to parse the below from JSON (using the JSON gem) in Ruby:
"daily":{"summary":"Light rain today through Saturday, with temperatures rising to 88°F on Saturday.","icon":"rain","data":[{"time":1435464000,"precipProbability":0.99}]}
Currently what I have is this: forecast["daily"]["data"], but I want to get the precipProbability for time "1435464000". Any suggestion on how to complete my current JSON parsing "query"?
Sometimes I need to use helper methods in controllers (sanitization methods, rendering text back to the view, various other applications). What's the right way? I've got:
self.class.helpers.myhelperview_context.myhelperinclude MyHelper; myhelperhelper MyHelper; myhelperI am unable to get the "like" action to work.
I am basing my action on the Raiscast no 364:
I believe my problem lies with the route:
resources :polls do
resources :likes, only: [], defaults => { :likeable => 'poll' } do
member { post :like }
end
end
Has defined the following route:
like_poll_like POST /polls/:poll_id/likes/:id/like(.:format) likes#like {:likeable=>"poll"}
I see here that the route is looking for an id for both the poll and the like however the controller action is to create a new row for in the likes table for the poll so there is no id for the like.
My like controller is:
class LikesController < ApplicationController
before_filter :load_likeable
def like
like = @likeable.likes.new(value: params[:value], user_id: current_user)
if like.save
redirect_to :back, notice: "Thank you for voting."
else
redirect_to :back, alert: "Unable to vote, perhaps you already did."
end
end
private
def like_params
params.require(:like).permit(:value)
end
def load_likeable
resource, id = request.path.split('/')[3,4]
@likeable = resource.singularize.classify.constantize.find(id)
end
def likeable_id
params[(params[:likeable].singularize + "_id").to_sym]
end
end
Here is the helper I am unable to get to work:
<%= link_to "Click here", polymorphic_url(poll, action: :like, value: 1), method: "post" %> to vote for <%= poll.option %>
This returns the following error:
undefined method `like_poll_url' for #<#<Class:0x007f4dbf3d4668>:0x007f4dbf308ba8>
I do not want to move the like action into the polls controller as likes is polymorphic and the same functionality will be reused.
I often have problems with translations. I remember this had to do with some translations using :many, but yet when I see an error message like this
translation data {:one=>"1 month", :other=>"%{count} months"} can not be used with :count => 3
...it shouldn't make any sense, isn't :other supposed to handle all other cases ??

I'm learning The Ruby on Rails Tutorial and currently going through the sections on embedded Ruby for the html (.html.erb) files. Is it necessary to use embedded Ruby in the html files? Are there major advantages besides code reusability? I'm trying to simply the learning process as much as I can and I'd like to skip the embedded Ruby/html parts if possible.
I have a Rails application that is using Devise for authentication and Angular on it's fontent to have a SPA application.
Now currently what I do is that when the user first loads the page, the user gets served a static html page with some angular on it. User can enter the credentials there and then press button to log in.
Now when the user logs in successfully then server will redirect the user back on the index page, but now I check on html page that current_user exists and then render and div that has ng-view in it. From here on every page change is done with ng-route and every request to the server is done with Angular.
Now as I understand, as long as the client making Ajax requests is under the same domain then the session cookies will be sent also along with requests. So technically the user should be checked on every request and all should be fine?
But is this a good way of handling the whole situation? Also what will happen when I later want some mobile apps to also be able to log in into that server and fetch some info form there?
The logged_in? method in the code doesn't use the @ sign to reference the current_user instance variable, does this mean that the variable is local to the logged_in? method or does it still reference the @current_user variable? I noticed if I write !@current_user instead of !current_user the method doesn't work correctly. I am slightly confused how this is working under the hood because would if I had a local variable in logged_in? named current_user and I did not want it to reference the @current_user instance variable above.
def current_user
@current_user ||= User.find_by(id: session[:user_id])
end
def logged_in?
!current_user.nil?
end
I am creating a chat module for my application and using private_pub for sending and receiving messages. I want to update the unread message counter on receiver's as soon as receiver gets the message.
Each page is subscribed to a channel where message gets published, so that every time I get the message, the counter on the page gets updated.
Following js file is executed when a new message is created.
<% publish_to conversation_messages_path(@conversation.id) do %>
$("#messages").append("<%= escape_javascript render(:partial => 'message', :locals => { :message => @message })%>");
$("#unread_messages_count").text("<%= current_user.received_messages.unread.size %>");
<% end %>
// @conversation.messages.where(:read => 0)
$("#newMessageForm")[0].reset();
$("#messages").scrollTop($("#messages")[0].scrollHeight);
The page gets updated but current_user.received_messages.unread.size gives me the sender's unread count, why is this so?
This means the current_user should be different for every other page who has subscribe_to that URL. As of now current_user is the one who publish_to that URL which results in the same value of unread messages count for every different client.
One possible solution is to send the user id of the one who is currently logged in while we subscribe_to a URL and in publish_to use that to get the unread messages count but the problem is I don't know how to send data while subscribing and using it in publish.
I would like to know how I could use ActiveRecord in the routes.rb file on my Rails application.
I am creating some optional modules which can be enabled or disabled dynamically. I don't want the routes to exists if the module is disabled so I created a condition around the optional routes. In development it's work properly but in the test environment, my query returns nil even if my fixtures are properly settled.
How can I make tests to use my fixtures when I am using OptionalModule.all ?
Thanks !
Here is my routes.rb file:
Rails.application.routes.draw do
optional_modules = OptionalModule.all # this returns nil in test mode
# by_name is a scope defined in the model
if optional_modules.by_name('GuestBook').enabled?
get 'toggle_guest_book_validated/:id', to: 'admin/guest_books#toggle_guest_book_validated', as: :toggle_guest_book_validated
end
end
My fixtures:

I am trying to make an app with Rails and Simple Form with country_select.
I am getting an error that says:
wrong number of arguments (4 for 0)
I am using the example that i found, for simple form on the country select gem documentation page. I don't understand what's going wrong.
In my model I have:
geocoded_by :address
after_validation :geocode, if: ->(obj){ @obj.address.present? and @obj.address_changed? }
def address
[city, state, participation_country].compact.join(', ')
end
In my form I have:
<%= f.simple_fields_for :scope do |participants_s| %>
<%= participants_s.simple_fields_for :participant do |par| %>
<%= par.select :participation_country,
priority: ["AU", "GB", "NZ", "US"],
selected: :participation_country,
label: false,
prompt: "Select participation country" %>
In my view I have:
<%= @project.scope.participant.address %>
Can anyone see what I have done wrong in trying to set this up? The error message indicates the problematic line is:
<%= par.select :participation_country,
I can't count 4 of anything except suggested country codes, although I deleted one of those to try and I get the same error.
I want to stop users who aren't logged in from accessing the URL using CanCanCan
My Ability model is
class Ability
include CanCan::Ability
def initialize(user)
user ||= User.new # guest user (not logged in)
if user.admin?
can :manage, :all
elsif user.roles.size > 0
can :manage, User, :id => user.id
else
can :read, :all
cannot :read, :User
end
end
end
And my Users controller is
class UsersController < ApplicationController
load_and_authorize_resource
def index
@users = User.paginate(page: params[:page],:per_page => 5)
end
def new
# @user = User.new
end
...
end
When I access the page as an guest user. I see the users index page instead of being redirected to login by this code in my application controller
rescue_from CanCan::AccessDenied do |exception|
if user_signed_in?
flash[:error] = "Access denied!"
redirect_to root_url
else
flash[:error] = "Please Sign in"
redirect_to new_user_session_path
end
end
CanCanCan works and stops access to the other actions in the controller just not for index.
Two models, Organization and User, have a 1:many relationship. I have a combined signup form where an organization plus a user for that organization get signed up.
The problem I'm experiencing is: When submitting invalid information for the user, it renders the form again, as it should, but the error messages (such as "username can't be blank") are not displayed. The form does work when valid information is submitted and it does display error messages for organization, just not for user.
How should I adjust the code below so that also the error messages for user get displayed?
def new
@organization = Organization.new
@user = @organization.users.build
end
def create
@organization = Organization.new(new_params.except(:users_attributes))
#Validations require the organization to be saved before user, as user requires an organization_id. That's why users_attributs are above excluded and why below it's managed in a transaction that rollbacks if either organization or user is invalid. This works as desired.
@organization.transaction do
if @organization.valid?
@organization.save
begin
# Execute next line in debugger (with invalid user info) correctly responds with: ActiveRecord::RecordInvalid Exception: Validation failed: Email can't be blank, Email is invalid, Username can't be blank, etc.
@organization.users.create!(users_attributes)
rescue
# Should I perhaps add some line here that adds the users errors to the memory?
raise ActiveRecord::Rollback
end
end
end
if @organization.persisted?
flash[:success] = "Yeah!"
redirect_to root_url
else
@user = @organization.users.build(users_attributes) # Otherwise the filled in information for user is gone (fields for user are then empty)
render :new
end
end
The form view includes:
<%= form_for @organization, url: next_url do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<%= f.text_field :name %>
# Other fields
<%= f.fields_for :users do |p| %>
<%= p.email_field :email %>
# Other fields
<% end %>
<%= f.submit "Submit" %>
<% end %>
The error messages partial is as follows:
<% object.errors.full_messages.each do |msg| %>
<li><%= msg.html_safe %></li>
<% end %>
Update: Following the steps from Rob below I arrived at an errors partial below. This still does not display error messages for User. I added debugger responses inside the code below and for some reason nested_model.errors.any? returns false, while the debugger inside the controller (see above) does return error messages for user.
<% if object.errors.any? %>
<div id="error_explanation">
<div class="alert alert-danger">
The form contains <%= pluralize(object.errors.count, "error") %>.
</div>
<ul>
<% object.errors.full_messages.each do |msg| %>
<li><%= msg.html_safe %></li>
<% end %>
</ul>
</div>
<% end %>
<% if defined?(nested_models) && nested_models.any? %>
# Debugger: responds with "local-variable" for "defined?(nested_models)" and for "nested_models.any?" returns true.
<div id="error_explanation">
<ul>
<% nested_models.each do |nested_model| %>
# Debugger: "nested_model" has the same values as "nested_models.any?", as you would expect. But for "nested_model.errors.any?" it returns false, which it shouldn't.
<% if nested_model.errors.any? %> #Initially had "unless nested_model.valid?" but then errors for User are immediately displayed on loading the form page (new method).
<ul>
<% nested_model.errors.full_messages.each do |msg| %>
<li><%= msg.html_safe %></li>
<% end %>
</ul>
<% end %>
<% end %>
</ul>
</div>
<% end %>
I'm trying to understand how the format option works in the groupdate gem.
The readme explains that format takes a string that is passed to strftime or a proc (here).
I'm having trouble understanding the proc part of this.
A simple example, if User.group_by_month(:created_at).count.keys returns [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12] (i.e., months of the year), how would I do a simple transformation of these keys, say key * 2?
Looking at the source, format appears to be expecting a method
if options[:format].respond_to?(:call)
options[:format]
end
So I would have expected to be able to do something like User.group_by_month(:created_at, format: 'Proc.new { |d| d * 2 }')....
But this returns only Proc.new { |d| d * 2} as a string.
What am I doing wrong?
I'm sure I'm being blind, can you spot something I've missed:
= f.select :region, options_for_select(YAML.load_file("#{Rails.root}/config/regions.yml").collect{|x| [x[1]['name'], x[0]]}), class: "form-control", style: 'display:none;'
Slim just ignores the class & style statements, but everything else looks fine. What am I doing wrong? (rails 4).
Given an input string like 3 days ago, how can I turn it into a date attribute? Maybe something like DateTime.parse('3 days ago')?
When got my database.yml configured like this:
default: &default
adapter: postgresql
encoding: utf8
pool: 5
timeout: 5000
production:
<<: *default
host: my_db_address
port: 5432
database: my_db_name
username: my_db_user_name
password: my_db_password
< test and development ommited >
When I establish connection like this:
ActiveRecord::Base.establish_connection
it says ActiveRecord::AdapterNotSpecified - 'production'
It works hovewer If I do it like this: ActiveRecord::Base.establish_connection( {:adapter => 'postgresql', :database => 'my_db_name', :host => 'my_db_address', :port => '5432', :username => 'my_db_user_name', :password => 'my_db_password'} )
I'd rather load the config from database.yml. How do I do this?

I want to use React with Rails. I already know html/JS, Begineer at Rails and just finished some tutorials on official site on React. Now I want to lear to use React with Rails. I noticed that many tutorials are using haml + coffescript. After researching on those two I found that they make developing easier and code more readable. But some people say that they generate bad html and JavaScript.
Is haml + coffescript worth learning for using them with React on Rails.
One of the reasons why I am not sure whether to use or not hamls/coffescript is that official documentation for React is written for Javascript.
so here is very small help i need for ROR , since i m a newbie in rails community. i m trying to create a model in rails named chat where i have two columns user1 and user2 , i want to store the user object in these. in grails i do this simply as
class Chat {
User user1
User user2
Date chatStartedOn
}
and i m done , i did somewhat same for rails
rails generate model Chat user1:User user2:User chatStartedOn:date
but i run db:migrate it showing me the error
undefined method `User' for #<ActiveRecord::ConnectionAdapters::TableDefinition
my user migrate file
class CreateUsers < ActiveRecord::Migration
def change
create_table :users do |t|
t.string :username
t.string :email
t.string :encrypted_password
t.string :salt
t.timestamps
end
end
end
Please guide how do i save users object in chat table.. help !

Why Paperclip does this request? It seems that it checks if the file still exists on the sever before giving the url, to avoid giving the broken ones.
Is there a way to stop it from doing the check so it simply returns the url without doing additional requests?

How to create a form with ability to add dynamically children and also children of children if needed (preferably with nested_form_for). In other words form shall be something like:
input
child input
child input (child of child)
add/remove child (child of child of child)
add/remove child (child)
add/remove input
Clicking add/remove will add/remove one more according child, how can I achieve this?
I can't find something that'll lead in the right direction. Everyone else's similar issues with nested resources seems to resolve around accepts_nested_attributes_for… which I'm not trying to do. I'm not trying to save children from the parent, I'm trying to save directly from the child.
In my routes.rb, I have nested my resource
resources :parents, param: :parent do
resources :children, param: :child
end
parent and child tables both have their own id column, but also have unique index on columns parent and child respectively, which I was to be used in the URL instead of the id.
This is working fine browsing around going to the show, edit and index actions of each controller.
The problem is there are exceptions saving data.
I'm hoping the root-cause of the issue doesn't come down to a field in the child table is also called child as that's what I've used to override to_param in the model and need to keep it that way.
Navigating to the edit screen: http://ift.tt/1HoWN5u and pushing submit on the form, returns this NoMethodError exception:
NoMethodError at /parents/harry/children/sally
undefined method `permit' for "sally":String
I'm sure the problem is something to do with how my Strong Parameters line is in children_controller.rb. Can I add to require a hash of :parent and :child maybe?
def children_params
params.require(:child).permit(:child, :date_of_birth, :nickname)

Im trying to use Searchkick to run a search and return based on multiple models.
My book model contains this
class Book < ActiveRecord::Base
searchkick
has_many :book_subjects
has_many :subjects, through: :book_subjects
belongs_to :author
belongs_to :publisher
end
and then my controller has this
def index
if params[:search].present?
@books = Book.search(params[:search], operator: "or")
else
@books = Book.all
end
end
I want the search results to search the associated models and return any results there too -- so the boo subject name, the author and the publisher.
thanks
I just need to know how to install ruby and rails. I am trying to do this from two days but no result. Actually I dont have any idea about this.
I am trying to make an app with Rails 4 and simple form.
I have three models - Project, Project_Question and Project_Answer. I made all of these by generating scaffolds so all naming conventions have been followed.
My resources are nested:
resources :projects do
resources :project_questions do
resources :project_answers
end
end
I am trying to use the console to find project answers created in my testing, but when I try to search for project answers:
2.1.1p76 :001 > Project_Answer.where(:answer => [hgvbhjb]).first
I get this error message:
LoadError: Unable to autoload constant Project_Answer, expected /app/models/project_answer.rb to define it.
The other problems on this site that seem to get the same error messages appear to be where people have not named their model.rb files in the singular. I have that.
I can only think that there is an extra step required to search the console if resources are nested. Does this sound plausible? If so, are there any materials to help figure out how to search the console with nested resources?
Can anyone see what has gone wrong?
I want to use FormBuilder's datetime_select helper to create dropdowns for a datetime field and want to specify which minute values to use in the drop down (let's say, I want to use 0, 15, 30 and 45.)
Is there some hidden option to f.datetime_select that will let me do this?
I have a Deal model that features a json column called deal_info. It's actually an array of JSONs.
I'm using active admin.
For example :
deal1.deal_info = [ { "modal_id": "4", "text1":"lorem" },
{ "modal_id": "6", "video2":"yonak" },
{ "modal_id": "9", "video2":"boom" } ]
deal2.deal_info = [ { "modal_id": "10", "text1":"lorem" },
{ "modal_id": "11", "video2":"yonak" },
{ "modal_id": "11", "image4":"boom" } ]
As first step now I would like to have a filter that would enable me to filter the deals based on the fact that deal_info json column includes at least one time the modal_id in one of its included json.
It would enable me in a select dropdown to choose for example modal_id = 6 and would filter the list of Deals to only show deal 1 (see example above).
One of the further challenge is that I need to be able to remove duplicates on the select dropdown in order not to have multiple times the same id: here for example i can't have select = [4,6,9,10,11,11]...each modal_id can only appear once.
I only found this but it did not work for me.
My current Active Admin Code
ActiveAdmin.register Deal do
filter :modal_id,
as: :select
collection: deal_info.all.to_a.map ????
end
EDIT after Andrei answer that helped move forward but not (yet) solve the problem
I added this code :
models/deal.rb
class Deal < ActiveRecord::Base
store_accessor :deal_info, :modal_id
end
# using http://ift.tt/1LNYzLh
ransacker :modal_id do |parent|
Arel::Nodes::InfixOperation.new('->', parent.table[:deal_info], 'modal_id')
end
inside active admin Deal file
ActiveAdmin.register Deal do
filter :modal_id,
label: 'modal id',
as: :select,
collection: -> { Deal.all.pluck(:info_throbber).flatten.map {|el| el['modal_id'] }.uniq }
It seems to PARTLY work but not completely. Indeed it does show me on the dropdown the right various modal_id's and they are well de-duplicated BUT when I select one of them on the dropdown, and click FILTER on the right side (where the filter sidebar is), it load the whole page again WITHOUT applying the filter.
For example, on my modal_id dropdown, i have the chocie between ANY/4/5/8. If I choose modal_id 5 and click the FILTER button when the page with all the deals (that should be filtered on modal_id = 5) load, inside the sidebar modal_id select dropdown, I don't see 5 as I had chosen but ANY. The value of 5 was not "KEPT"/"REMEMBERED" and it got back to the value ANY. I don't understand why.
I asked in a question LINK how it was the best way to manage two databases MySQL for a Rails Web App. I searched "web services" in internet and i found a lot of things. My questions are:
1) I have to program an app in Rails, is it usefull to create the web service for this app in Rails too?
2) I have to use two databases , in my Web service how can i have to manage this?
for example, i need the list of the users of the DB1, so i write:
http://localhost:3000/users/
but how do i have to program the web service to be able to separate the two databases? I mean , if i need the users od the DB2 i would use an url like the before one:
http://localhost:3000/users/ (but for DB2)
3) I know that in a web service we should create the WSDL file. But is really necessary in my case? i will not publish the web service so , i think is not necessary to create the WSDL. is it?
Sorry for the newbie questions but it's my first time in web service programming.
I'm running Rails 4 and am trying to use a bootstrap form wizard. The thing about the form wizard is that not all of its tabs should be displayed at all times.
The form wizard is in a partial that I render via $("#tab3").html("<%= j(render partial: 'wizard' ) %>"); in update_forms.js.erb (called via an ajax call).
Everything works well in this except the progress bar doesn't display (it is 0) unless I refresh the page. Any thoughts on how I can set the progress bar when rendering the partial?
I've never seen this error before, I don't want a staging database, but it keeps asking for it?
Message from application: 'staging' database is not configured. Available: ["default", "development", "test", "production"] (ActiveRecord::AdapterNotSpecified)
Is there a way around this?
I need to order a query of Profile entries in an ActiveRecord::Relation object by a value that is computed on run-time.
I have created and assigned a temporary column distance in my controller for the Relation object by using attr_accessor like so:
@profiles.each do |p|
p.class_eval do
attr_accessor :distance
end
end
@profiles.each do |p|
p.distance = distance_arr[@profiles.index(p)] # Distance values obtained from an instance array
end
However, when I try to order the Relation with the order method, I get a no such column: distance error i.e. it's not picking up the temporary field.
Here's how I tried to order it in my controller (note I'm using the will_paginate gem, but that is irrelevant).
@profiles = @profiles.order('distance ASC').paginate(page: params[:page])
I am creating a CRM(Customer relationship management) in Rails. I have to use two databases(MySQL).I have a doubt in the correct use of these databases.
I mean, i read on internet that is possible to open two connections in a Rails project, but is this the right way to hit the problem? is really good to open two connection in a project?
is it used?if not, what is the solution in the state of art(maybe the simpler to manage queries) for my problem?
I have been using Koala gem for firing FQL queries to fetch facebook data. Normally all FQL queries are GET resquests but I have seen that in facebook's Graph API explorer if the query is too long, its automatically converted to a POST request. Does the Koala gem also exhibits a similar behaviour ?
I have a helper that looks like this:
if current_user.find_voted_items(vote_scope: :inspired).include?(post)
link_to vote_inspired_post_path(post, vote_scope: :inspired), method: :post, data: { confirm: 'Are you sure this post Inspires you?' }, class: "btn btn-default" do
"<i class='fa fa-lightbulb-o'></i> <br />Inspired".html_safe
end
link_to vote_happy_post_path(post, vote_scope: :happy), method: :post, data: { confirm: 'Are you sure this post makes you happy?' }, class: "btn btn-success" do
"<i class='fa fa-smile-o'></i> <br />Happy".html_safe
end
link_to vote_disappointed_post_path(post, vote_scope: :disappointed), method: :post, data: { confirm: 'Are you sure this post disappointed you?' }, class: "btn btn-info" do
"<i class='fa fa-meh-o'></i> <br />Disappointed".html_safe
end
link_to vote_upset_post_path(post, vote_scope: :upset), method: :post, data: { confirm: 'Are you sure this post upsets you?' }, class: "btn btn-inverse" do
"<i class='fa fa-frown-o'></i> <br />Upset".html_safe
end
end
I need all the links and their nested <i> tags to be rendered - but for some reason, this version is just rendering the last line.
All of that is inside a method called show_vote_buttons(post), that is being called like this in the view: <%= show_vote_buttons(@post) %>
What's the best way to tackle this?

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.

Rails 4.2.1
I am currently trying to implement raising an error when unpermitted parameters are posted in my RoR back-end. I included
config.action_controller.action_on_unpermitted_parameters = :raise
in my development.rb configuration. Now, for example I have in one of my controllers:
def apiary_params
params.require(:apiary).permit(:name, :municipality, :prefecture, :latitude, :longitude, :numberofbeehives, :notes)
end
If I now try posting another parameter lets say "apiary[asdf]" then an internal server error is raised correctly. However if I try posting a random "asdf" param not in the apiary hash, then the request is handled without an error. Does that mean that the random "asdf" and whatever other parameter not in the apiary is permitted? How can I fix that?
I have an S3 bucket where images are uploaded to. All of my static content is served via a Cloudfront distribution however, or at least it should be.
When I look at my page source, it indicates that all static content, except for the images in my S3 bucket, is served from Cloudfront. The images in S3 is still served from S3.
I have played around with my settings, but nothing seems to be fixing this issue.
Currently in my Cloudfront distribution I have the following settings:
Origin Pointing to my S3 Bucket:
-Origin Domain name pointed to my S3 Bucket
Any idea on what might cause this setup not to retrieve my S3 content via Cloudfront?
I know there are three main types of syntax's for the where clause:
Specifying AND for the where clause is straight forward:
#Pure String syntax
@people= Person.where("name = 'Neil' AND age = 27")
#Array syntax
@people = Person.where(["name = ? AND age = ?", 'Neil', 27])
#Hash syntax
@people = Person.where({name: "Neil", age: 27})
Specifying OR for this same where clause is stumping me for the hash syntax. Is it possible?
#Pure String syntax
@people= Person.where("name = 'Neil' OR age = 27")
#Array syntax
@people = Person.where(["name = ? OR age = ?", 'Neil', 27])
#Hash syntax DOESN'T WORK
@people = Person.where({name: "Neil" OR age: 27})
My search controller does this:
search = Sunspot.search(Item) do
fulltext params[:q] do
fields(:foo, :bar, :bletch)
end
end
And in my rspec controller test I have the following:
get :show, :q => q
expect(Sunspot.session).to have_search_params(:fulltext, q, proc do
fields(:foo, :bar, :bletch)
end)
Side note: when I tried using a block instead of a proc, the block was never executed:
have_search_params(:fulltext, q) do
# This block was never executed
end
My support/sunspot.rb contains only the following:
Sunspot.session = SunspotMatchers::SunspotSessionSpy.new(Sunspot.session)
When I run the test, I get the following error:
1) SearchController GET search when a user runs a search performs a fulltext search on the right fields
Failure/Error: fields(:foo, :bar, :bletch)
NoMethodError:
undefined method `fields' for #<Sunspot::DSL::Search:0x007fa0f0da0168>

# ./spec/controllers/search_controller_spec.rb:27:in `block (4 levels) in <top (required)>'
What's the right way to test that my controller is supplying the correct params when doing a fulltext search? Google yields no relevant results when querying this problem.
This question sounds very similar to those that have already been asked and answered thought I can't seem to figure it out.

[I]s there any way to develop android apps using ruby? [I]f any[,] please enlighten me on this,[ ]and please let me know the frameworks used.
i have several views, as well as some gems, that access the filesystem. this seems to work fine until i run the server as a daemon. rails (4.2.3)
for example in one of my views I access the README file in the root of the app
File.read('README.md')
when running as a daemon, i get the error No such file or directory @ rb_sysopen - README.md
the error page shows the Rails.root path, which is correct. i CAN fix this problem by doing:
File.read("#{Rails.root}/README.md")
however this issue breaks more than just my views. It would seem an issue with the rails server.

I'm trying to setup a form for tasks where the user selects a game and the achievements that belong to it, following Ryan Bates' tutorial. The only difference between that tutorial and what I'm working on is that I have a has_many through association in my Task model.
