Question

I’m beginner at Rails, and im actually stuck with apparently a “beginner problem”.

I got a “sounds” scaffolded controller, and i had to add an action “sendit”. I can’t have access to the sound from my view to my controller.

This is my error when i try to access to “http://127.0.0.1:3000/sounds/sendit.14” (Why it’s sendit.14 and not sounds/sendit/14 or sounds/14/sendit ?)

ActiveRecord::RecordNotFound in SoundsController#sendit

Couldn't find Sound without an ID

Application Trace | Framework Trace | Full Trace
app/controllers/sounds_controller.rb:74:in `sendit'
Request

Parameters:

{"format"=>"14"}

Here is my code :

Sound Controller :

def sendit
    @sound = Sound.find(params[:id]) # ----- Error is on this line -----
    # Do Job
  end

Index.html.erb

<% @sounds.each do |sound| %>
  <% if sound.user_id == current_user.id %>
    <tr>
      <td><%= sound.title %></td>
      <td><%= sound.user.email %></td>
      <td><%= link_to 'Show', sound %></td>
      <td><%= link_to 'Edit', edit_sound_path(sound) %></td>
      <td><%= link_to 'Destroy', sound, method: :delete, data: { confirm: 'Are you sure?' } %></td>
      <td><%= link_to 'Send', sounds_sendit_path(sound) %></td>

routes.rb

  devise_for :users

  match "/sounds/sendit/", :controller => "sounds", :action => "sendit"

  resources :users, :sounds

I did this in the route file because of Adding an action to an existing controller (Ruby on Rails)

When i do rake routes , this is the output :

              [...]
           sounds_sendit        /sounds/sendit(.:format)       sounds#sendit 
                   users GET    /users(.:format)               users#index
                         POST   /users(.:format)               users#create
                new_user GET    /users/new(.:format)           users#new
               edit_user GET    /users/:id/edit(.:format)      users#edit
                    user GET    /users/:id(.:format)           users#show
                         PUT    /users/:id(.:format)           users#update
                         DELETE /users/:id(.:format)           users#destroy
                  sounds GET    /sounds(.:format)              sounds#index
                         POST   /sounds(.:format)              sounds#create
               new_sound GET    /sounds/new(.:format)          sounds#new
              edit_sound GET    /sounds/:id/edit(.:format)     sounds#edit
                   sound GET    /sounds/:id(.:format)          sounds#show
                         PUT    /sounds/:id(.:format)          sounds#update
                         DELETE /sounds/:id(.:format)          sounds#destroy
                    root        /                              home#index

(I actually don’t understand the first line, why there is no POST / GET, and why it’s sounds_sendit and no sendit_sound like others default actions? How to fix it? )

Thank you for your help

Answer 1

Instead of this :

match "/sounds/sendit/", :controller => "sounds", :action => "sendit"

Use this:

  resources :sounds do
    member do
      get :sendit
    end
  end

Then you will be able to use the sendit_sound_path helper to link to the action correctly:

link_to "link text", sendit_sound_path(sound_object)

Hope this does it for you,…
