django.template.base.VariableDoesNotExist: Failed lookup for key [name] in RegexURLResolver

使用django自带的authenticate()进行登录认证的时候,post传的数据为username:XXXX,password:XXXX,需要与数据库中保存的字段名称一致,使用默认的AbstractUser作为模型类时,默认的字段米子为username,如果post传回的json对象中不是username时候,就会有以下错误:


mismissing attribute django.template.base.VariableDoesNotExist: Failed lookup for key [name] in '<RegexURLResolver <RegexURLPattern list> (admin:admin) admin/>

源码:

class ModelBackend(object):
    def authenticate(self, request, username=None, password=None, **kwargs):
        if username is None:
            username = kwargs.get(UserModel.USERNAME_FIELD)
        try:
            user = UserModel._default_manager.get_by_natural_key(username)
        except UserModel.DoesNotExist:
            # Run the default password hasher once to reduce the timing
            # difference between an existing and a non-existing user (#20760).
            UserModel().set_password(password)
        else:
            if user.check_password(password) and self.user_can_authenticate(user):
                return user```
