Rails add link to edit attribute from another model

If I have a model Product and a model Category.

I have a table in products index showing products with columns like:

 <td><%= product.ID %></td>
 <td><%= product.NAME %></td>
 <td><%= product.category.NAME %></td>

It shows values like:

1,salad, vegetable

2,apple,fruit

I want to be able to click on vegetable or fruit to edit them.

I tried:

<td><%= link_to product.category.NAME, [:edit, product.category] %>

This takes me to a page

categories/1/edit

which returns

Couldn't find Product with 'ID'=

Instead it should go to

categories/edit/1

In my routes I have:

 match ':controller(/:action(/:ID))', :via => [:get, :post]
 resources :categories

What is the correct syntax to use in this case?

To invoke the edit action on the category controller with your modified route specify the controller, action and id values like so:

<%= link_to product.category.NAME, { controller: :categories, action: :edit, ID: product.category.id } %>

The link_to helper will build the path correctly to match the category/edit/1 path and route to the edit action of the category controller instead of the product controller (assuming category.id == 1)
