問題描述

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’`

我已經(jīng)添加permission進(jìn)數(shù)據(jù)庫了，為什么程序還是提示這個(gè)問題？ 有沒有已經(jīng)完成flasky這個(gè)項(xiàng)目的前輩。指導(dǎo)一下唄，謝謝

問題解答

self.role為None,flasky完整項(xiàng)目https://github.com/miguelgrin...可以參考
