# 创建一个新角色并分配权限
def create_role(role_name, permissions):
    role = Role(name=role_name)
    role.permissions = permissions
    role.save()

# 为用户分配角色
def assign_role_to_user(user_id, role_name):
    user = User.get(id=user_id)
    role = Role.get(name=role_name)
    user.role = role
    user.save()

# 记录用户操作日志
def log_user_action(user_id, action, details):

log_user_action(user_id=123, action="login", details="User logged in at 2023-01-01 10:00:00")
