Comments on: Rails: Nested resource scaffold

By: Santiago GL

I am using Rails 1.2.4.
When recipes_controller.rb does NOT exist, the mapping to /recipes/1/ingredients does show the ingredients that belong to recipe 1.
That’s ok!
But when recipes_controller.rb DOES exist, the nested resource (/recipes/1/ingredients) outputs

Unknown action \ No action responded to 1

If I call /recipes/1.xml/ingredients it outputs a routing error, that is, there is no route to that resource.
What am I doing wrong?
Thanks

@Brian: Just like you nested ingredients into recipes, you can nest recipes in books. Note that this means that you’ll have to use books_recipe_ingredients_url(@book, @recipe, @ingredient))

You can do this. But if you stuff the same recipies in different books, I wouldn’t nest ‘em.

Good luck with your app.

What if recipes where in books. so you wanted book/:id/recipe/:id/ingredients
How would the route.rb look then - can you double nest or should you just not do this? We have a lot of these situations.

oops the code in my comment should be:
url_for([@matter.client, @matter]) do |f|

The form has: matters_path(@client, @matter)) do |f| %> which builds the url /matters/ rather than /clients/1/matters/ which is what I need for the proper save. Any advice?

I have been working on this same issue today the solution I found was
url_for([@cient.matter, @matter]) do |f| -%>
This generates the expected post URL /client/:client_id/matters so the controller can user the params[client_id] to scope the new matter to the correct client!

hope this helps

I guess the new stuff in trunk is to address problems like joost was having. that way it separates the calls to all recipes ingredients_path & recipe_ingredients_path(@recipe).

Just wanted to mention that in the latest Rails trunk, you have to prefix a nested resource with its parent. So ingredient_path(@recipe, @ingredient) will become recipe_ingredient_path(@recipe, @ingredient).

@joost: Just add map.resoureces :ingredients to your config/routes.rb

You’ll have ingredients twice there, but that’s no problem at all. I was amazed by this too when I found out, but it works perfectly.

I agree that nested routes are a thing of beauty, but once nested it seems impossible to ‘un-nest’ a resource.

What I am getting at is that I would like to

a) show the ingredients for one recipe. this works fine.

b) show a list of ingredients covering all recipies.

This latter doesn’t seem possible. Logically, the url would become /ingredients but these can only exist inside recipes (giving /recipes/2/ingredients).

Do you know a way to have both? List all ingredients for one recipe AND list them all for all recipes?
