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
end

  
  
  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 category.name, :controller=>"recipe", :action=>"list", :category=>category.name %></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...
