Question

我正在使用django构建应用程序，我决定选择allauth身份验证。现在我有一个个人资料页面，我希望用户能够编辑他们的帐户，包括Bios，Last_name，first_name和thingx，并且可能包含一个显示图片，但我添加了一些代码，我收到了一个错误，我已经存放了它很长一段时间。错误是

        email = self.cleaned_data.get('email')

        if email and User.objects.filter(email=email).exclude(username=username).count():
            raise forms.ValidationError('This email address is already in use. Please supply a different email address.')
        return email

    def save(self, commit=True):
        user = super(RegistrationForm, self).save(commit=False)
        user.email = self.cleaned_data['email']

        if commit:
            user.save()

        return user

这是我上面的代码与错误，我只是无法解决问题是什么。任何帮助将不胜感激。

Answer 1

此代码

class Meta:
    model = User
    fields = ('username', 'email', 'first_name', 'last_name')

不属于您的模型。因此，model和fields都是模型Meta类的无效关键字参数。

编辑回复评论：

如果您想添加更多字段，可以在模型中添加它们：

class MyModel(models.Model):
    my_new_field = models.IntegerField()

然后，在您的模型表单中，将my_new_field添加到fields参数中。请注意，除非您想要执行超出模型提供的功能，否则只需将其添加到tuple字段即可。换句话说，您不需要添加：

my_new_field = forms.IntegerField()

ModelForm会为您神奇地处理这个问题，如文档中所示：

https://docs.djangoproject.com/en/1.11/topics/forms/modelforms/#modelform

这是使用模型表单和模型视图集等优点。它通过重用模型的模式，推断字段和字段类型来保持代码DRY。

我希望能够解决问题。

Answer 2

删除attrs

class Profile(models.Model):
    # ... your code here
    class Meta: # And this line need to remove
        model = User # And this line need to remove
        fields = ('username', 'email', 'first_name', 'last_name') # this line need to remove

在Model meta中，您只能使用models options
