Signals from AdminUser and Role Models

The lback.admin.models.AdminUser and lback.admin.models.Role models emit signals during key operations related to administrative user permissions and role management. These signals provide critical hooks for auditing administrative actions, implementing fine-grained logging, and integrating with external systems for security monitoring or compliance purposes.

Signal Name	Description	Arguments (kwargs)
admin_user_permission_checked	Emitted after checking whether an AdminUser has a specific permission. This signal provides insight into permission evaluation outcomes.	sender (AdminUser): The instance of the AdminUser model.<br>``admin_user`` (AdminUser): The AdminUser object whose permission was checked.<br>``permission_name`` (str): The name of the permission that was checked.<br>``has_permission`` (bool): True if the user has the permission, False otherwise.<br>``reason`` (str): A string indicating why the permission was granted or denied (e.g., “is_superuser”, “found_in_role_permissions”, “not_found_in_role_permissions”, “no_role_or_permissions”).
role_permission_added	Emitted successfully after a new Permission has been added to a Role.	sender (Role): The instance of the Role model to which the permission was added.<br>``role`` (Role): The Role object itself.<br>``permission`` (Permission): The Permission object that was added.
role_permission_removed	Emitted successfully after a Permission has been removed from a Role.	sender (Role): The instance of the Role model from which the permission was removed.<br>``role`` (Role): The Role object itself.<br>``permission`` (Permission): The Permission object that was removed.
role_permission_operation_failed	Emitted if an attempt to add or remove a permission from a role fails (e.g., due to invalid type, permission already existing, or permission not found).	sender (Role): The instance of the Role model on which the operation failed.<br>``role`` (Role): The Role object itself.<br>``operation`` (str): The attempted operation (“add” or “remove”).<br>``permission`` (Permission): The Permission object involved in the failed operation (can be of any type if invalid_type).<br>``error_type`` (str): Describes the type of failure (e.g., “invalid_type”, “already_exists”, “not_found”).
