Response to: "Showing recipes in a category" code

I also think that using the recipe.category.id field is better - after all the recipe.category.name might not be unique.
And the code simplifies, so you can write the whole RecipeController.list method as:
def list
@recipes = Recipe.find_all(@params["category_id"] ? ("category_id = " + @params["category_id"]) : nil)
end
The code above passes to Recipe.find_all a category_id, if @params["category_id"] is not empty or nil otherwise.
Of course, the statement from list.rhtml that renders the category needs to be changed as:
<td><%= link_to recipe.category.name, :action => "list", :category_id => recipe.category.id %></td>
