In the tutorial was explaned how you can show the recipes related to a specific category. This was done from the recipes list page. This works fine!!!

Now I want to show my Recipes from my Category list page. Can somebody tell me how to do that?
I've been struggling for quite a while now..

  • How to?? : Showing related Recipes from the Category list

    Step 1:

    Create a list method for Category controller:

    def list
    @categories = Category.find_all

    Step 2:

    Since we changed the controller, we now have to create a custom view for the list method as app\controller\list.rhtml. You do the same as you did for recipe, but where you have the category name column, you'll use the code:

    <td><%= link_to, :controller=>"recipe", :action=>"list", :category=> %></td>

    This way, you're turning the category name into a link that will invoke the /recipe/list link while setting the @category to the selected category name.

    I just did that, and it worked for me...
