在 django 中编辑 allauth 帐户

Question

我正在使用 django 构建一个应用程序，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以包括 Bios、Last_name、first_name 和 thingx 之类的，并且可能包括一张显示图片，但我实施了一些代码，我得到了一个错误，我已经存放了很长时间了。错误是

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

        if commit:
            user.save()

        return user

这是我上面的错误代码，我只是想不通问题是什么 is.Any 将不胜感激。

Answer 1

删除属性

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

在模型元中你只能使用 models options

如果您想扩展默认的 django 用户模型，请阅读 auth customizing

Answer 2

这个代码

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

不属于您的模型。因此，model 和 fields 都是模型的 Meta class.

的无效关键字参数

编辑以回复评论：

如果您想添加更多字段，您可以将它们添加到您的模型中：

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，除非您想做一些超出您的模型所提供的事情，否则您只需将其添加到字段的 tuple 中。换句话说，您不需要添加：

my_new_field = forms.IntegerField()

ModelForm 为您神奇地处理了这个问题，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之类的优势。它通过重新使用模型的架构、推断字段和字段类型来保持代码干爽。

我希望事情已经解决了。

对于你的最后一个错误需要替换

class UpdateProfile(forms.ModelForm):
    # your code ...
    def save(self, commit=True):
        user = super(RegistrationForm, self).save(commit=False)
        #           ^^^^^^^^^^^^^^^^^

到

class UpdateProfile(forms.ModelForm):
    # your code ...
    def save(self, commit=True):
        user = super(UpdateProfile, self).save(commit=False)
        #           ^^^^^^^^^^^^^^^^^
