How do I implement nested resources in Rails?

To implement nested resources in Rails, you need to define them in your routes file. For example, if you have a posts resource and a comments resource, you can nest comments under posts like this: resources :posts do resources :comments end.

What are the benefits of using nested resources?

Nested resources help to establish a clear relationship between models, making it easier to manage related data. They also improve the organization of your routes.

Can you give me an example of how to create a comment for a specific post?

Sure! In your CommentsController, you can create a comment for a specific post by using the post's ID. For example: @post = Post.find(params[:post_id]) and then @comment = @post.comments.new(comment_params).

What if I want to add more levels of nesting?

You can add more levels of nesting by continuing to define resources within the block. For example, if you have likes for comments, you can do: resources :posts do resources :comments do resources :likes end end.
