Data Permissions

Casbin provides two approaches for implementing data-level permission filtering: querying implicit assignments or using batch enforcement.

1. Querying Implicit Roles and Permissions

When users inherit roles or permissions through an RBAC hierarchy rather than through direct policy assignments, these are called "implicit" assignments. To retrieve these relationships, use GetImplicitRolesForUser() and GetImplicitPermissionsForUser() instead of the standard GetRolesForUser() and GetPermissionsForUser() methods. Additional details are available in this GitHub issue.

2. Using BatchEnforce()

BatchEnforce() evaluates multiple access requests simultaneously and returns their results as a boolean array.

Zum Beispiel:

boolArray, err := e.BatchEnforce(requests)

const boolArray = await e.batchEnforce(requests);

List<Boolean> boolArray = e.batchEnforce(requests);
