Rails: URL being processed by incorrect controller action

Question

I have a URL that is being processed by the wrong controller action. In my routes file I have the following

post '/tweets' => 'tweets#create'

Whenever I post to this url it is instead processed by tweets#index.

Started POST "/tweets" for 127.0.0.1 at 2014-03-27 20:04:25 -0700
Processing by TweetsController#index as HTML
  Parameters: {"utf8"=>"✓", "authenticity_token"=>"CCN9rDQiSXkVK0sF/BGU19fIufJTpho/ocySPmu7Lsc=", "tweet"=>{"title"=>"sdfdsafdsa", "description"=>"sdfdsasdadsa", "user_id"=>"1"}, "commit"=>"Create Tweet"}
  Tweet Load (0.4ms)  SELECT `tweets`.* FROM `tweets` 
  Rendered tweets/index.html.erb within layouts/application (0.1ms)
Completed 200 OK in 42ms (Views: 40.6ms | ActiveRecord: 0.4ms)

I have tried restarting my rails server yet it still doesn't work.

Here is the result of rake routes

tweeter: rake routes
        new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
            user_session POST   /users/sign_in(.:format)       devise/sessions#create

                         POST   /tweets(.:format)              tweets#create
                    root        /                              tweets#index

Answer 1

That is because you have post '/tweets' => 'tweets#create' defined after other tweet routes.

Modify your route config by moving this line above other tweet routes:

# config/routes.rb
...
post '/tweets' => 'tweets#create'
resources :tweets, only: [ :index, :new ]
...
