Response to: Better way of filtering Recipes by Category

I completely agree that the best way to do this through the proper database queries within a method in the Recipe model.


Obviously, this article was not about best practices. :-)

    I'm not sure that this is any better but here is what I ended up with:

    Adding this method to RecipeController

    def list_category
    @recipes = Recipe.find_all_by_category_id(@params['id'])
    render_action "list"
    end


    And changing list.rhtml to make the category a link


    <td><%= link_to recipe.category.name, :action => "list_category", :id => recipe.category.id %></td>


    This could be HUGELY wrong since I've only spent about 45 minutes with rails and no time with ruby before that.

    Just like to say I thought the article was great. I also picked up that the view was not necessarily the best place to filter the categories and also that the category.id was probably a better attribute to search on.

    However, like you said the article was not about best practices. It gave me the chance to think on my own and see if I had learn't enough to write some of my own code. To my complete (albeit undeserved) surprise, I had picked up enough from your two tutorials (and a quick glance at the API docs) to make the changes I felt necessary.
