Scope
What is Scope?
- Scoping allows you to specify commonly-used queries which can be referenced as method calls on models or association objects
- With these scopes, you can use every method previously covered such as where, joins and includes
- All scope methods will return an ActiveRecord::Relation object which will allow for chaining further methods (such as other scopes)
