| Rails Devise flash key is always being set to alert Posted: 27 Mar 2016 06:12 AM PDT I used this link to add flash messages to my rails app. The alerts show up, however the key is not set to success, notice or danger. Instead when I check the class of the flash messages from the browser, it has a class of alert-alert and as a consequence isn't styled properly. Why is devise setting the key to alert, and how can I get the right keys to be sent? Thanks! [UPDATE] The error messages like "password is too short" do show up with the class of alert-danger, but the flash messages like "you have signed in" still don't grab the right key. What am I doing wrong? |
| Rails Validations and the DRY principle Posted: 27 Mar 2016 06:34 AM PDT I have 9 different models, all with a column called 'name'. In each model I have the following validation: validates :name, presence: true, uniqueness: true
To adhere to the DRY principle, should that validation go in a parent class and have my models that use that validation inherit from the parent class? |
| Ruby BigDecimal multiplication Posted: 27 Mar 2016 06:35 AM PDT I'm in trouble with Bigdecimal multiplication. I have a column: t.decimal "average_price", precision: 8, scale: 2
My sample average_price looks like "3.59280368". When I'm try to make some calculations with this value, I get: @itam.average_price * 1000000 = 3590000
Why not 3592803? |
| Couldn't pass params to ticket purchase action Posted: 27 Mar 2016 05:11 AM PDT I am building an application where a user can find an event and buy a ticket to that event. Here are my files: tickets/new.html.erb: <%= form_tag('/ticket/finish') do %> <% @event.ticket_types.each do |ticket_type| %> <tr> <td><%= ticket_type.name %></td> <td> <%= number_to_currency(ticket_type.price, unit: 'VND ', precision: 0) %></td> <td> <%= select_tag(:quantity, options_for_select(0..10)) %></td> </tr> <br> <% end %> <p> <%= submit_tag 'Purchase Ticket', class: 'btn btn-primary' %> </p> <% end %>
tickets_controller.rb: class TicketsController < ApplicationController def new @event = Event.find(params[:event_id]) @ticket = Ticket.new end def purchase end end
event.rb: class Event < ActiveRecord::Base belongs_to :user belongs_to :venue belongs_to :category has_many :ticket_types validates_associated :ticket_types validates_presence_of :user validates_presence_of :name, :extended_html_description, :hero_image_url # validates_presence_of :venue, :category validates_uniqueness_of :name,scope: [:venue_id, :starts_at] def has_ticket_types? !!self.ticket_types.present? end end
ticket_types.rb: class TicketType < ActiveRecord::Base belongs_to :event validates_presence_of :name, :price, :max_quantity validates_uniqueness_of :name, scope: :event_id end
routes.rb: Rails.application.routes.draw do devise_for :users root 'events#index' get '/yourevents', to: 'events#user_events' resources :events do resources :tickets end post '/ticket/purchase', to: 'tickets#purchase' get 'ticket/finish', to: 'tickets#finish' resources :events do resources :ticket_types end resources :venues end
My goal is I want when user click the 'purchase ticket' button, it will lead them to a page that shows them the ticket types, and the quantity of those ticket types they have just bought. However, I have no idea how can I pass those params in my purchase action since I don't have a ticket model. Could anybody here give me some hint or guide me to the right direction? Thank you in advance. |
| Rendering tree structures in Rails Slim template Posted: 27 Mar 2016 04:24 AM PDT There are several cases of tree structures in an app I am working on. Currently these have been coded in Ruby helpers (generally just as a bunch of string con-cats and occasional use of other helpers), but Id rather them be coded directly in the relevant views (most are one-off HTML structures), or partials where being reused. But is it possible to render such a recursive structure in Slim (other than recursively invoking a partial for the recursive part, which still splits it into at least 2 files). e.g. a simple tree might be like this: <div id="table-of-contents" class="tree"> <h1>Table of Contents</h1> <ol> <li><a href="/somepage/">1 Header</a> <ol> <li><a href="/somepage/sub">1.1 sub-Header</a> <ol> <li><a href="/sompage/sub#sub">1.1.1 Sub-sub-header</a></li> </ol> </li> <li><a>1.2 sub-Header</a></li> </ol> </li> <li><a>2 Header 2</a></li> <ol> </div>
Thinking something like this, but this is not valid syntax -def toc_tree(prefix, items) ol -for item, i in items.each_with_index li a href=item.url ="#{prefix}#{i} #{item.name}" - if item.children? =toc_tree("#{prefix}#{i}.", item.children) div#table-of-contents.tree h1 Table of Contents =toc_tree("", @toc)

| NodeJS + Socket.Io or ActionCable? Posted: 27 Mar 2016 04:11 AM PDT I am trying to create a real-time app right now and I'm tossing up between Rail's newest feature in ver.5 ActionCable and node.js + Socket.io. If I wanted to analyse chat messages in real-time, which framework would you recommend? I heard that mongoDB, node and socket is really quick at storing information but maybe not as robust as rails when it comes to analysis? Would be great to have some additional thoughts! |

| How to model in rails, users login to input days of each month they are available to attend Posted: 27 Mar 2016 03:49 AM PDT Thinking of building a web application to be shared amongst the local volunteer lifeguards. They log in and create a profile with their name, email and phone number. But most importantly update their monthly availability from a page that presents the days of the month in a checkbox fashion.

| Obtain a Facebook app access token using Koala and Ruby on Rails Posted: 27 Mar 2016 03:12 AM PDT I've been trying to use my RoR app to connect to the Facebook API for a day without any luck. I'm using Ruby on Rails and Koala. If I try to connect as follows: graph = Koala::Facebook::API.new(User_Token)
Then there is no problem. (Where user token was obtained from https://developers.facebook.com/tools/access_token/) The problem is that the user token expires. I am aware that there is a way to extend the app User Token, but I would rather not resort to this. Rather, I am trying to authenticate my app to obtain an APP ACCESS TOKEN which I can use in lieu of the User Token (as per https://developers.facebook.com/docs/facebook-login/access-tokens#apptokens. Please note this refers to the App Access Token, not the App Token which was referred to in the first link). In order to obtain the App Access Token, I have followed a tutorial and provided this code in my controller: id = <my app id> secret = <my app secret> callbackUrl = "http://localhost:3000/events/appcallback" @ouath = Koala::Facebook::OAuth.new(id, secret, callbackUrl) redirect_to @oauth.url_for_oauth_code()
in my routes.rb I have: match "events/appcallback" => "events#appCalledBack", via: :get
This is purely to test that the callback worked. My intention was then to do something like: App_Access_Token = @oauth.get_access_token(params[:code])
But instead I get an error: NoMethodError in EventsController#index undefined method `url_for_oauth_code' for nil:NilClass Please note that I am not interested in obtaining an access token for a user; I want one for my app, so that I can connect to the api a la: graph = Koala::Facebook::API.new(App_Access_Token)
Any help would be greatly, greatly appreciated. |
| Validates Uniqueness Method to follow only one time Posted: 27 Mar 2016 07:19 AM PDT I create a following system exactly like that with users (Devise). I followed the Ryan Bates Rails casts http://railscasts.com/episodes/163-self-referential-association In this code we can add numerous times the same user, I want to block when people has added as a friend. For example when User1 has added a User2 the link will be block. I give you some codes to understand. The migration is called FriendShip class CreateFriendships < ActiveRecord::Migration def change create_table :friendships do |t| t.integer :user_id t.integer :friend_id t.timestamps null: false end end end
The model for users is has_many :friendships has_many :friends, :through => :friendships
The model for Friendship is belongs_to :user belongs_to :friend, :class_name => "User"
The Friendship controller class FriendshipsController < ApplicationController def create @friendship = current_user.friendships.build(:friend_id => params[:friend_id]) if @friendship.save flash[:notice] = "Added friend." redirect_to current_user else flash[:error] = "Unable to add friend." redirect_to current_user end end def destroy @friendship = current_user.friendships.find(params[:id]) @friendship.destroy flash[:notice] = "Removed friendship." redirect_to current_user end end

| Using a Controller Method with Resque Background Job Posted: 26 Mar 2016 10:49 PM PDT I am on Rails 4 using Resque w/ Redis. My question: How can I use a controller method, which is currently defined in my application_controller, inside of my background job? Here is the current method I have defined: def push_to_google(token, message) if token.present? gcm = GCM.new("843jf9384fj839f848j890fj3") registration_ids = ["#{token}"] # an array of one or more client registration tokens options = {data: {notification: "#{message}"}} response = gcm.send(registration_ids, options) end end
which I would like to use in this background job defined in my delayed_notifications: class DelayedNotifications @queue = :notifications_queue def self.perform(registration_id, user_name) push_to_google(registration_id, "New message from #{user_name}.") end end
Of course, my jobs are currently failing with this error: undefined method 'push_to_google' for DelayedNotifications:Class
Thanks for the help in advance. |
| Rails Active Record Seems to Be Broken, Rails 4.0.2 Posted: 26 Mar 2016 10:34 PM PDT O.k. this is driving me crazy - if anyone could help that would be great. I have a simple table "threads" with an auto id and a "name" field with one record (id = 1, name = "space"). I have a model named "Thread.rb". class Thread < ActiveRecord::Base end
I have a controller that calls: @thread = Thread.find_by_id(1)
But when loading a page I get the following error in the controller: undefined method `find_by_id' for Thread:Class
I've used find_by_sql numerous times in the same project with no problem, but when using the simple activerecord accessors rails errors out on "find", "find_by_id" etc. I'm on rails 4.0.2 |
| Rails Engine: Create dummy model for relations? Posted: 26 Mar 2016 10:42 PM PDT I am trying to make a Rails Engine that can be plugged into my applications and manage friendships between users. To do that, all the logic dealing with friend requests, acceptance, etc, is going to live in a Rails Engine. When I create my Friendship model, it needs a belongs_to relation for two Users (two friends). But, I don't want to tie a user to this engine. I want this engine to work generically with any User an application has established. What technique does one use to create a dummy User that is never to be included in the host application? (I want to avoid a migration of the engine pulling in this dummy User.) Update: I removed the second question, pertaining to how to then override the engine's User with the host app's User. I found the answer to that in the guides (http://edgeguides.rubyonrails.org/engines.html#configuring-an-engine). |
| Partial Rendered in index.html.erb Won't Display in show.html.erb Posted: 26 Mar 2016 10:39 PM PDT A beginner here, so, please bear with me. :) I have a partial in a partial that's displaying correctly in my views > products > index.html.erb: <div> <table> ... <tbody> <%= render product %> </tbody> ... </table> </div>
This is the _product partial: <div> <td> <%= render "product_row", product: product, order_item: @order_item %> </td> </div>

All is well, BUT I want to display _product_row in my views > products > show.html.erb instead. So, I copy and paste it and get this error: NameError in Products#show undefined local variable or method `product' for #<#<Class:...> Extracted source: <%= render "product_row", product: product, order_item: @order_item %>
...so I go in my products_controller and put this: def show @product = Product.find(params[:id]) respond_to do |format| format.html # show.html.erb format.json { render json: @product } end end
'still the same error. Any help will be appreciated. Thanks! |
| rspec model test on string match regex adjustment Posted: 26 Mar 2016 09:08 PM PDT I have the following test in rspec it 'passes regex rules' do job = create(:job) job.valid? expect(job.title).to match(/\A[\w\d .,:-@]+\z/) end
This regex pattern matches the model pattern. What is the recommended way to test to make sure this pattern does not change in the model from future developers? Basically I want to test for conditions that do not fall in the approved: can only have 0-9, A-Z, periods, colons, hypens, underscores, and spaces. No new lines (enter keys) Update Based on Generate random string based on Regex? I decided to go with (0..255).map(&:chr).select{|x| x != /\A[\w\d .,:-@]+\z/}.sample(5).join for now which appears to work, thoughts? |

| Rails Enum on Relationship Model cannot be called from separate controller? Posted: 26 Mar 2016 09:56 PM PDT I have a Relationship model in which i establish a following relationship between users and projects. In this relationship model i use enum to distinguish the type of relationship the user has with the project (basically establishing a "role"). Now in my Projects Controller I am trying to call the projectadmins action def projectadmins @title = "Project Admins" @project = Project.find(params[:id]) authorize @project, :visit? @projects = @project.followers render 'show_projectadmin_project' rescue Pundit::NotAuthorizedError flash[:danger] = "You are not authorized to access this page." redirect_to projects_path || root_path end
My Relationships model is: class Relationship < ActiveRecord::Base belongs_to :follower, class_name: "User" belongs_to :followed, class_name: "Project" validates :follower_id, presence: true validates :followed_id, presence: true enum role: [:admin, :collaborator, :visitor] end
User & Projects Models: class User < ActiveRecord::Base has_many :own_projects, :class_name=>'Project' has_many :projects has_many :relationships, foreign_key: "follower_id", dependent: :destroy has_many :followed_projects, through: :relationships, source: :followed end class Project < ActiveRecord::Base belongs_to :owner, :foreign_key=>'user_id', :class_name=>'User' has_many :reverse_relationships, foreign_key: "followed_id", class_name: "Relationship", dependent: :destroy has_many :followers, through: :reverse_relationships, source: :follower end
'show_projectadmin_project' view: <h3>Project Administrators</h3> <% if @project.projectadmins.any? %> <% @project.projectadmins.each do |user| %> <div class="no-pad col-md-3"> <div class="inner-border"> <h5><%= link_to user.email, user %></h5> </div> </div> <% end %> <% end %>
As is, my code in the controller method is setup to return all following relationships ("@projects = @project.followers")...my question is how can i change this line of code to return all following relationships that have an enum role type of :admin? I assume something like "@projects = @project.followers where (etc, etc)" but I can't seem to find anything that has worked for me. |
| Feature test failing when trying to use "check" Posted: 26 Mar 2016 08:29 PM PDT I'm new to feature tests and capybara, I have a real simple feature test right now and I can't get it to pass but I believe it's because of something I'm doing wrong writing the test.

| Rails Background Job for Creating Records? Posted: 26 Mar 2016 08:31 PM PDT Currently on Rails 4 with Resque. My question is, would it make sense to use a background job for creating a record? Something like... def create @article = Article.new(articles_params) if @article.valid? background_job_here else render 'new' end end
The only other documentation I can find on this matter says that it does not make sense to do this, however, does not explain why. Reading Heroku documentation, they suggest that any request taking more than 500 ms be moved off into the background. Creating an article on my site is no exception as it can take upwards of 1,000 ms. If not a background job, how should I architect this? Thx! |

| Searchkick rails geospatial search not working Posted: 26 Mar 2016 05:37 PM PDT I'm trying Searchkick on a small Rails app to perform geospatial searches, but I can't get it to work. I have a Venue model: class Venue < ActiveRecord::Base has_and_belongs_to_many :categories searchkick locations: ["location"] def search_data attributes.merge location: [latitude, longitude] attributes.merge categories_title: categories.map(&:name) end end
I have added data to my database, and I have run Venue.reindex too. In my controller I'm trying to search by running: term = "london" res = Geocoder.search(term) @location = res.first.geometry['location'] # lat / lng @venues = Venue.search '*', where: { location: { near: [@location['lat'],@location['lng']], within: '2km' } }
Although I have valid data in my database, I always get an empty result. Looking at rails console, the query executed against elasticsearch is: { "query":{ "filtered":{ "query":{ "match_all":{ } }, "filter":{ "and":[ { "geo_distance":{ "location":[ -0.08077990000000002, 51.5037119 ], "distance":"2km" } } ] } } }, "size":1000, "from":0, "sort":{ "_geo_distance":{ "location":"51.5037119,-0.08077990000000002" } }, "fields":[ ] }

| Implementing PJAX - Configuring Server Posted: 26 Mar 2016 05:31 PM PDT My first question here. I searched thoroughly, and unfortunately, I am unable to find an explanation I can understand. I am interested in understanding how PJAX works (link below), so that I can consider implementing it. It seems simple enough, but the requirement to configure the server to recognize PJAX requests has me stumped. I am a front-end developer that is completely unfamiliar with back-end development. For example, how do I configure the server? The PJAX author gives an example in RAILS, so it is a matter of placing that code wherever it goes? I build custom and implement Wordpress, and I use a Wordpress hosting solution. Does that affect where I would configure the server? I know these are general questions, which demonstrate how little I know. I would appreciate if someone could explain the concept of configuring the server and perhaps provide an example of what that would look like. I appreciate your help. https://github.com/defunkt/jquery-pjax |

| Show and update nested attributes in rails form Posted: 27 Mar 2016 02:27 AM PDT I have an :item model with nested attributes from :item_galleries showcasing multiple images. I'm able to create an item with the nested images but having issues with editing. I want to be able to show each image attached to the item and able to edit each one.
