How do I use scopes in Active Record?

Scopes in Active Record are custom queries that you can define in your models. They allow you to encapsulate common queries and reuse them easily.

Can you give me an example of a scope?

Sure! You can define a scope like this: scope :active, -> { where(active: true) }. This will return all records where the active attribute is true.

How do I use this scope in a query?

You can use the scope in your queries like this: User.active to get all active users.

Can I chain scopes together?

Yes, you can chain scopes! For example, if you have another scope scope :recent, -> { order(created_at: :desc) }, you can do User.active.recent to get active users sorted by creation date.
