Question

I have set up a site that is correctly using basic CRUD functionality succesfully. However, when I try to add a custom method to my controller I cannot seem to hook it up to a link_to call. I keep getting a method not found error.

The Controller method looks like this:

def complete
    return render :text => "Complete"
end

and my call in the View looks like this:

<%= link_to 'Complete', complete_list_task_path(@list,@task) %>

This same call works for my Edit method, so I’m not sure what I’m doing wrong. Do I need to do anything special when the method is not a basic CRUD call?

The only relevant part of my route file looks like this (List and Task are nested resources. List has many tasks, and task belongs to a list):

resources :lists do
    resources :tasks
end

I have also tried adding post "complete" => "lists/:id/tasks/:id#complete", :as => "complete" to my route to see if it would help to implicitly try to call it, but I still got a “method not found error”.

Any help in figuring out how to make this call would be greatly appreciated. Thank you!

Answer 1

You need to declare the method in the router, ‘resources’ refers to the 7 crud actions (index, new, create, edit, update, delete, show).

Off the top of my head, I think you’d need:

resources :lists do
  resources :tasks do
    member do
      post :complete
    end
  end
end

The nesting makes me less confident, but that’s the general thing you need to do.
