Django error with User form: AttributeError: 'tuple' object has no attribute '_meta'

Question

我按照课程使用 Django 进行用户注册，他编写了这段代码，就像我所做的那样：

class CustomUserForm(UserChangeForm):
    username = forms.CharField(
        widget=forms.TextInput(attrs={'class': 'form-control my-2', 'placeholder': 'Enter Username'}))
    email = forms.CharField(
        widget=forms.TextInput(attrs={'class': 'form-control my-2', 'placeholder': 'Enter The Email'}))
    password1 = forms.CharField(
        widget=forms.PasswordInput(attrs={'class': 'form-control my-2', 'placeholder': 'Enter The Password'}))
    password2 = forms.CharField(
        widget=forms.PasswordInput(attrs={'class': 'form-control my-2', 'placeholder': 'Confirm Password'}))

    class Meta:
        model = User,
        fields = ['username', 'email', 'password1', 'password2']

当运行服务器显示此错误时：

PS E:\osamaStartup> py manage.py runserver

class CustomUserForm(UserChangeForm):
    username = forms.CharField(
        widget=forms.TextInput(attrs={'class': 'form-control my-2', 'placeholder': 'Enter Username'}))
    email = forms.CharField(

    password1 = forms.CharField(

    password2 = forms.CharField(
        widget=forms.PasswordInput(attrs={'class': 'form-control my-2', 'placeholder': 'Confirm Password'}))

    class Meta:
        model = User,  # Remove this comma because its treating it as a tuple
        fields = ['username', 'email', 'password1', 'password2']
