<flask web 开发>项目permission问题

问题作者 : Jewison2017-06-06发布

AttributeError: 'NoneType' object has no attribute 'permission'
---------------------------------------------------------------`
{% if current_user.can(Permission.MODERATE_COMMENTS) %}

File "/home/centos/Desktop/workspace/flasky_163/app/models.py", line 207, in can

    def generate_email_change_token(self, new_email, expiration=3600):

        s = Serializer(current_app.config['SECRET_KEY'], expiration)

        return s.dumps({'change_email': self.id, 'new_email': new_email})

 

    def can(self, permission):

        return (self.role.permission & permission) == permission

 

    def is_administrator(self):

        return self.can(Permission.ADMINISTER)

 

    def ping(self):

AttributeError: 'NoneType' object has no attribute 'permission'`


我已经添加permission进数据库了,为什么程序还是提示这个问题? 有没有已经完成flasky这个项目的前辈。指导一下呗,谢谢
