Django更改密码问题,super(type,obj):obj必须是类型的实例或子类型

Question

我在使用changepassword表单时遇到了一些问题,它继续给我同样的错误:super(type,obj):obj必须是类型的实例或子类型

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

有任何想法吗？

您的问题在这一行:

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

它应该是

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

当您从另一个表单复制时,它可能是一个复制粘贴问题.
