Django Password Reset Confirm 错误（自定义用户模型）；更新

Question

我没有编写 Python/后端的经验，但正在努力改进。在开发/本地服务器中，我正在尝试创建密码重置表单...但是从忘记密码的电子邮件中访问链接时出现以下错误-在此之前密码未保存：

init() 缺少 1 个必需的位置参数：'user'

forms.py（几乎从 Django 的表单中复制/粘贴；微小的变化）

class ResetPasswordForm(SetPasswordForm):
    error_messages = {
        'password_mismatch': static_textLanguage['page_user_passwordReset_alert_passwordNotMatch'],
        'password_empty': static_textLanguage['global_alert_mandatoryField'],
        'minimum_length': static_textLanguage['global_alert_minCharacters_password'],
    }
    new_password1 = forms.CharField(
        required=False,
        widget=forms.PasswordInput(attrs={
            'id': 'page_userPasswordReset_content_form_input_passwordA',
            'maxlength': '25',
            'class': 'global_component_input_box'
        }),
    )
    new_password2 = forms.CharField(
        required = False,
        widget=forms.PasswordInput(attrs={
            'id': 'page_userPasswordReset_content_form_input_passwordB',
            'maxlength': '25',
            'class': 'global_component_input_box'
        }),
    )
    
    def __init__(self, user, *args, **kwargs):
        self.user = user
        super(ResetPasswordForm, self).__init__(user, *args, **kwargs)

    def clean_new_password1(self):
        password1 = self.cleaned_data.get('new_password1')
        if password1 == '' or password1 is None:
            raise forms.ValidationError(self.error_messages['password_empty'], code='password_field_empty')
        elif len(password1) < 8:
            raise forms.ValidationError(self.error_messages['minimum_length'], code='password_too_short')
        return password1

    def clean_new_password2(self):
        password1 = self.cleaned_data.get('new_password1')
        password2 = self.cleaned_data.get('new_password2')
        if password2 == '' or password2 is None:
            raise forms.ValidationError(self.error_messages['password_empty'], code='password_field_empty')
        if password1 and password2:
            if password1 != password2:
                raise ValidationError(self.error_messages['password_mismatch'], code='password_mismatch')
        password_validation.validate_password(password2, self.user)
        return password2

    def save(self, commit=True):
        password = self.cleaned_data["new_password1"]
        self.user.set_password(password)
        if commit:
            self.user.save()
        return self.user

class UserPasswordResetView(auth_views.PasswordResetConfirmView):
    template_name = '../frontend/templates/frontend/templates.user/template.page_passwordReset.html'
    form_class = ResetPasswordForm
    post_reset_login = True
    success_url = reverse_lazy('page_userLoginPrivate')

    def get_form_kwargs(self):
        kwargs = super().get_form_kwargs()
        kwargs['user'] = self.user
        return kwargs

    def get_context_data(self, *args, **kwargs):
        context = super().get_context_data(*args, **kwargs)
        if self.validlink:
            context.update({
                'validlink': True,
                'form': self.form_class(),

该错误很可能发生，因为您将 user 定义为位置参数 (def __init__(self, user, *args, **kwargs):)，但您将变量作为关键字参数 (kwargs['user'] = self.user) 传递。

代替你的代码：

class ResetPasswordForm(SetPasswordForm):
    ...

    def __init__(self, user, *args, **kwargs):
        self.user = user
        ...

尝试将其更改为此（以便ResetPasswordForm 在kwargs 中查找user）：

class ResetPasswordForm(SetPasswordForm):
    ...

    def __init__(self, *args, **kwargs):
        self.user = kwargs['user']
        ...
