“AnonymousUser”对象在登录期间没有属性“_meta”

Question

我在Django 1.11中有一个应用程序，我的问题是一个错误：

'AnonymousUser' object has no attribute '_meta'

它出现在登录时。以前用户是使用自定义注册表单创建的（我使用的是email地址而不是username）。用户已创建，因为我可以登录/admin/的管理面板。

以下是我的登录表格：

class LoginForm(AuthenticationForm):
    email = forms.CharField(label='Email',
                               max_length=50,
                               widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Email',
                                                             'type': 'text', 'id': 'email'}))
    password = forms.CharField(label='Password',
                               max_length=50,
                               widget=forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Password',
                                                             'type': 'password', 'id': 'password'}))

    field_order = ['email', 'password']

    def __init__(self, *args, **kwargs):
        super(LoginForm, self).__init__(*args, **kwargs)
        self.fields.pop('username')

要在记录时使用email，请在模型USERNAME_FIELD = 'email'中添加它，然后重试。
