How to specify different action for link_to helper?

Question

I'm creating a website where users can mark and unmark items as "favorite". I implemented this via Ajax using Rails' form attribute remote: true so whole page does not reloaded, just status of item is changed.

I have two methods in FavouritesController

def create
    Favourite.create!(item_id: params[:favourite][:item_id])    
    respond_to { |format| format.js }
end

def destroy
    Favourite.find(params[:id]).destroy!
    respond_to { |format| format.js }
end

The problem is:

I want to call another action from the same controller to "unmark" item in another view. I use code below but when I click on link - old method destroy is called from controller, instead of desired delete_from_index_list method. I need two separate methods because they returns different javascript (jquery).

<%= link_to "delete", @favourite, method: :delete, remote: true, action: 'delete_from_index_list'  %>

Check out the link_to documentation - I this will describe what you want.

I haven't tested this, but I'm guessing you want:

<%= link_to "delete", controller: 'favourites', action: 'delete_from_index_list', id: @favourite, remote: true %>

If it were my code, I would find the route for the delete_from_index_list method, and call it this way:

<%= link_to "delete", route_for_delete_from_index_list_path(@favourite), method: :delete %>

This way it's more resourceful, whereas the former example is non-resourceful.
