Django更改密码问题，super(type, obj): obj must be an instance or subtype of type

Question

我的 changepassword 表单有问题，它继续给我同样的错误：super(type, obj): obj must be an instance or subtype of type

这是我的表格：

class PasswordChangeForm(forms.Form):
    current_password = forms.CharField(label=u'Current Password', widget=forms.PasswordInput(render_value=False))
    new_password = forms.CharField(label=u'New Password', widget=forms.PasswordInput(render_value=False))
    retyped_password = forms.CharField(label=u'Retype New Password', widget=forms.PasswordInput(render_value=False))

    def __init__(self, data=None, user=None, *args, **kwargs):
        self.user = user
        super(UserProfileEditForm, self).__init__(data=data, *args, **kwargs)

    def clean_current_password(self):
        cleaned_data = self.cleaned_data
        current_password = cleaned_data.get('current_password', '')

        if not self.user.check_password(current_password):
            raise ValidationError('Wrong current password.')

        return current_password

    def clean(self):
        cleaned_data = self.cleaned_data
        new_password = cleaned_data.get('new_password', '')
        retyped_password = cleaned_data.get('retyped_password', '')

        if len(new_password) == 0 or len(retyped_password) == 0:
            raise ValidationError('Blank password fields.')

        if new_password != retyped_password:
            raise ValidationError('New password and retyped password do not match.')

        return cleaned_data

    def save(self):
        self.user.set_password(new_password)
        return self.user

有什么想法吗？

您的问题在这一行：

super(UserProfileEditForm, self).__init__(data=data, *args, **kwargs)

应该是

super(PasswordChangeForm, self).__init__(data=data, *args, **kwargs)

当您从其他表单复制时，这可能是复制粘贴问题。
