django-rules functions as a modular authorization framework, centered around a Core Rule Engine that manages and evaluates defined rules. The fundamental building blocks are Predicates, which represent individual logical conditions and are managed by the Predicate Definition & Management component. Applications interact with this system primarily through the Permission API Layer, which provides a high-level interface for defining and checking permissions. This API layer then delegates the actual rule evaluation to the Core Rule Engine. For seamless integration into Django applications, dedicated components like Django Admin Integration, Django View Integration, and Django REST Framework Integration leverage the Permission API Layer to enforce authorization logic across various parts of a Django project, ensuring a clear separation between the core rule evaluation logic and its application-specific enforcement.
Predicate Definition & Management [Expand]
The foundational layer responsible for defining, combining, and evaluating individual logical conditions (predicates). It provides the primitives for building complex rules.

Core Rule Engine [Expand]
The central component that stores, manages, and evaluates the defined rules. It acts as the brain of the rule-based system, determining if a rule is satisfied by evaluating its constituent predicates.
Related Classes/Methods:
Serves as the primary public interface for applications to interact with the django-rules system. It provides a high-level API for defining, querying, and managing permissions, abstracting direct interaction with the Core Rule Engine.
Related Classes/Methods:
Provides specific integration points for Django's administrative interface, enabling django-rules to enforce object-level and model-level permissions within the Django admin site.
Related Classes/Methods:
Offers utilities and decorators to seamlessly integrate django-rules permission checks directly into Django views, controlling access based on defined rules.
Related Classes/Methods:
Extends django-rules functionality to Django REST Framework, allowing for fine-grained permission control over API endpoints and resources.
