如何使用我自己的自定义表单覆盖 django-rest-auth 中的表单？

我正在使用 django-rest-auth，并尝试通过覆盖表单的方法之一来修复密码重置视图中的错误。尽管我已经使用不同的 django-rest-auth 表单成功完成了类似的操作，但我无法让它在这个表单上工作。无论我做什么，都会使用旧的形式。

api/urls.py

from django.urls import include, path
from django.contrib.auth import views
from django.conf.urls import include, url
from django.views.generic.base import RedirectView
from .forms import SetPasswordFormCustom
from .forms import PasswordResetFormCustom

urlpatterns = [
    path('password/reset/',
        views.PasswordResetView.as_view(form_class=PasswordResetFormCustom),
        name='rest_password_reset'),
    path('rest-auth/', include('rest_auth.urls')),
    path('rest-auth/registration/', include('rest_auth.registration.urls')),
    path('users/', include('users.urls')),
    path('reset/<uidb64>/<token>/',
        views.PasswordResetConfirmView.as_view(template_name='account/password_reset_confirm.html', form_class=SetPasswordFormCustom),
        name='password_reset_confirm'),
    path('reset/done/', views.PasswordResetCompleteView.as_view(template_name='account/password_reset_complete.html'),
        name='password_reset_complete'),
    path('content/', include('lists.endpoints')),
    # content is a path for lists, items etc found in the lists app
]

forms.py

from django import forms
from django.contrib.auth.forms import SetPasswordForm
from django.contrib.auth import (
    authenticate, get_user_model, password_validation,
)
from django.utils.translation import gettext, gettext_lazy as _
#from django.contrib.auth import password_validation

from django.contrib.auth.forms import PasswordResetForm
UserModel = get_user_model()

class SetPasswordFormCustom(SetPasswordForm):
    new_password1 = forms.CharField(
        label=_("New password"),
        widget=forms.PasswordInput(attrs={'class':'form-control','placeholder':'Password'}),
        strip=False,
    )
    new_password2 = forms.CharField(
        label=_("Confirm new password"),
        strip=False,
        widget=forms.PasswordInput(attrs={'class':'form-control','placeholder':'Confirm password'}),
        help_text=password_validation.password_validators_help_text_html(),
    )

class PasswordResetFormCustom(PasswordResetForm):
    def get_users(self, email):
        print('using custom form');
        """Given an email, return matching user(s) who should receive a reset.

        This allows subclasses to more easily customize the default policies
        that prevent inactive users and users with unusable passwords from
        resetting their password.
        """
        active_users = UserModel._default_manager.filter(**{
            '%s__iexact' % UserModel.get_email_field_name(): email,
            'is_active': True,
        })

        if not active_users:
            raise forms.ValidationError(_("The e-mail address is not assigned to any user account"),
                code='invalid')
        return (u for u in active_users if u.has_usable_password())

所以，我不明白的是，没有使用 PasswordResetFormCustom 及其对 active_users 的检查。当我请求密码重置电子邮件时，“使用自定义表单”行不会打印在服务器日志中，并且不会执行检查。

我的其他自定义表单PasswordResetConfirmView 工作正常。

没有错误，因此并不是导入不正确。

知道如何自定义 get_users 方法而无需编辑 django-rest-auth 文件吗？

谢谢你的帮助！

编辑：我将 yofee 的代码放入文件 serializers.py 中，而且我还必须修复 urls.py 中 url 路径的顺序。现在可以了！

url 模式 = [ ... 路径（'rest-auth /密码/重置/'，PasswordResetView.as_view（））， 路径('rest-auth/', include('rest_auth.urls')), ... ]

重置路径必须位于包含之前。

解决方案应该是

1. not set PasswordResetFormCustom在你看来但在你的序列化器中
2. use the rest_auth's PasswordResetView（不是姜戈的）

Example:

from django.contrib.auth.forms import PasswordResetForm as DjangoPasswordResetForm
from rest_auth.serializers import (
    PasswordResetSerializer as RestAuthPasswordResetSerializer
)
from rest_auth.views import PasswordResetView as RestAuthPasswordResetView
from django.utils.translation import ugettext_lazy as _
from rest_framework.exceptions import ValidationError

class PasswordResetForm(DjangoPasswordResetForm):
    def get_users(self, email):
        users = tuple(super().get_users(email))
        if users:
            return users
        msg = _('"{email}" was not found in our system.')
        raise ValidationError({'email': msg.format(email=email)})


class PasswordResetSerializer(RestAuthPasswordResetSerializer):
    password_reset_form_class = PasswordResetForm


class PasswordResetView(RestAuthPasswordResetView):
    serializer_class = PasswordResetSerializer

    def __init__(self, *args, **kwargs):
        """Prints the name of the class if it is used."""
        print(self.__class__.__name__)
        super().__init__(*args, **kwargs)
