ActiveRecord::DynamicScopeMatch

Active Record Dynamic Scope Match

Provides dynamic attribute-based scopes such as scoped_by_price(4.99) if, for example, the Product has an attribute with that name. You can chain more scoped_by_* methods after the other. It acts like a named scope except that it’s dynamic.
