Python Django角色权限-可用的#u权限为'；t自动分配给组

我正在尝试使用

django角色权限

，但它不会将

available\u权限

分配给组或用户

from rolepermissions.roles import AbstractUserRole

class PERMISSIONS:
    CAN_SEE_ALL_INVOICES = 'can_see_all_invoices'
    CAN_SEE_OWN_INVOICES = 'can_see_own_invoices'

class Admin(AbstractUserRole):
    verbose_name = 'Admin'
    available_permissions = {
        PERMISSIONS.CAN_SEE_ALL_INVOICES:True,
    }

class Broker(AbstractUserRole):
    verbose_name = 'Maklér'
    available_permissions = {
        PERMISSIONS.CAN_SEE_ALL_INVOICES: False,
        PERMISSIONS.CAN_SEE_OWN_INVOICES: True,
    }

在

sync\u roles

之后，我检查了管理员，并尝试以编程方式检查拥有

Broker

角色但没有权限的用户的权限

这怎么可能
