Undefined method in controller (Routing)

I'm new at rails and I'm currently working on an already existing application that handles butons like so:

<%= link_to 'Edit', edit_answer_path(ans) %>

That links to the file /answers/edit.html.erb but now I need to make a button that links to the file /answers/comment.html.erb how do I go about doing this?

I already tried with 

<%= link_to 'Comment', comment_answer_path(ans) %>

but I get the error "Undefined method 'comment_answer_path'" even after adding this lines to answers_controller :

def comment
  ans = Answer.find(params[:id])
end

It depends on how you've set up the routes in routes.rb.

You can use rake routes to see the list of all paths and their alias.

You need to add a route to your config/routes.rb and then restart the server. Something like

resources :answers do
  member do
    get 'comment'
  end
end

will create the comment_answer_path helper for you as well.
