How can I use advanced collections in Ruby on Rails?

In Ruby on Rails, advanced collections can be managed using ActiveRecord's query interface. You can use methods like where, joins, and includes to manipulate and retrieve data efficiently.

Can you give me an example of using includes?

Sure! If you have a Post model that belongs to a User, you can fetch posts with their associated users like this: Post.includes(:user).all.

What about using scopes with collections?

You can define scopes in your model to encapsulate common queries. For example, in your Post model, you could have scope :published, -> { where(published: true) } and then call Post.published to get all published posts.

You can use the kaminari or will_paginate gem for pagination. For example, with kaminari, you can call Post.page(params[:page]).per(10) to paginate your posts.
