Django1.9：'function' 對象沒有屬性 '_meta'

Question

Django 給出錯誤信息

表格.py：

from django import forms
from django.contrib.auth import authenticate, get_user_model, login, logout
from django.contrib.auth.forms import UserCreationForm

User = get_user_model


class UserLoginForm(forms.Form):
    username = forms.CharField()
    password = forms.CharField(widget=forms.PasswordInput)

    def clean(self, *args, **kwargs):
        username = self.cleaned_data.get("username")
        password = self.cleaned_data.get("password")
        user = authenticate(username=username, password=password)
        #user_qs = User.objects.filter(username=username)
        #if user_qs.count() == 1:
        #   user = user_qs.first()
        if username and password:
            user = authenticate(username=username, password=password)
            if not user:
                raise forms.ValidationError("This user does not exist.")
            if not user.check_password(password):
                raise forms.ValidationError("Incorrect password.")
            if not user.is_active:
                raise forms.ValidationError("User is not active.")
        return super(UserLoginForm, self).clean(*args, **kwargs)


class InceptionForm(forms.ModelForm):
    email2 = forms.EmailField(label='Confirm Email')
    class Meta:
        model = User
        fields = ('username', 'email', 'password1', 'password2')

由於類 InceptionForm() 發生錯誤。

錯誤：

AttributeError: 'function' 對象沒有屬性 '_meta'

Answer 1

您已將 User 設置為等於函數get_user_model 。 您需要將其設置為調用該函數的結果：

User = get_user_model()

Answer 2

該庫生成用戶模型表單：

from django.cotrib.auth import get_user_model

將 auth 用戶連接到 user_model_form：

User = get_user_model()
