Consul

Allows defining powers as ActiveRecord scopes or boolean checks, enabling precise access control from simple role-based scenarios to complex, context-dependent rules, as demonstrated with notes and users.

Integrates directly with Rails controllers via current_power and power directives, making it easy to protect actions and map powers to RESTful endpoints without boilerplate code.

Supports querying powers dynamically by name, model, or record, facilitating generic helper methods and flexible logic, as detailed in the dynamic power access section with examples like include_record?.

Leverages the assignable_values gem to restrict attribute assignments based on user context, adding an optional authorization layer to models for fields like states or associations.
