Rails calling deleted Controller - ruby-on-rails

Question

Basic Rails problem here:
I have a controller method named fetch_headlines that I've been trying to debug. I make changes to the controller and they are not reflected in the output. This has made me think that Rails is not properly calling fetch_headlines. Observe the console below.

Additionally, Rails is presenting the same behavior if I request methods that don't exist such as: qwertyqwerty. I'd expect Rails to throw an error.

Here is my routes.rb
get 'fetch_headlines', to: 'entries#fetch_headlines'
resources :entries
resources :keywords
resources :networks
Thanks.

You put get 'fetch_headlines', to: 'entries#fetch_headlines', it creates /fetch_headlines instead of /entries/fetch_headlines route. What you need is rather something like this:
get 'entries/fetch_headlines', to 'entries#fetch_headlines'
or even better
resources :entries do
collection do
get :fetch_headlines
end
end
