Django 4.0重置密码链接指向旧表单，如何改为allauth表单地址？

近期将项目升级至Django 4.0，同时升级了django-allauth与dj-rest-auth。当用户在http://localhost:8000/api/dj-rest-auth/password/reset/提交密码重置表单后，控制台生成的链接为http://localhost:8000/users/reset/2n/bxggn2-05019c81f9d6dfda6a10b7cfec09e839/，该链接指向旧版Django内置的密码重置表单。希望控制台输出的链接指向django-allauth的密码重置表单地址accounts/password/reset/key/1-set-password/。

以下是当前的配置文件：

settings.py #

INSTALLED_APPS = [
    # Local,
    'api.apps.ApiConfig',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.humanize',
    'django.contrib.sessions',
    'django.contrib.messages',
    'whitenoise.runserver_nostatic',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'users',

    # 3rd Party
    'rest_framework',
    'rest_framework.authtoken',
    'allauth',
    'allauth.account',
    'allauth.socialaccount',
    'dj_rest_auth',
    'dj_rest_auth.registration',
    'corsheaders',
    'drf_yasg',
]

AUTHENTICATION_BACKENDS = [
    'django.contrib.auth.backends.ModelBackend',
    'allauth.account.auth_backends.AuthenticationBackend',
]


REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAdminUser',
        'rest_framework.permissions.IsAuthenticated',
    ],
    'DEFAULT_AUTHENTICATION_CLASSES': [
       'rest_framework.authentication.SessionAuthentication',
       'rest_framework.authentication.TokenAuthentication', 
    ],
      'DEFAULT_SCHEMA_CLASS': 'rest_framework.schemas.coreapi.AutoSchema'
}

urls.py #

from django.urls import path, include
from allauth.account.views import ConfirmEmailView, EmailVerificationSentView 

urlpatterns = [
    path('accounts/', include('allauth.urls')),
    path('', include('users.urls')),

    path('api/', include('api.urls')),
    path('api-auth/', include('rest_framework.urls')),

    path('api/dj-rest-auth/registration/account-confirm-email/<str:key>/',
         ConfirmEmailView.as_view()), # Needs to be defined before the registration path

    path('api/dj-rest-auth/', include('dj_rest_auth.urls')),
    path('api/dj-rest-auth/registration/', include('dj_rest_auth.registration.urls')),

    path('api/rest-auth/registration/account-confirm-email/', 
         EmailVerificationSentView.as_view(), name='account_email_verification_sent'),

    path('', include('django.contrib.auth.urls')),    
    path('users/', include('users.urls')),
    path('users/', include('django.contrib.auth.urls')),

]

dj-rest-auth默认使用Django内置的密码重置流程生成链接，要替换为allauth的表单地址，需要自定义密码重置序列化器并调整配置：

• 创建自定义序列化器
  在users应用下新建serializers.py，添加以下代码：

from dj_rest_auth.serializers import PasswordResetSerializer
from allauth.account.forms import ResetPasswordForm
from django.conf import settings

class AllauthPasswordResetSerializer(PasswordResetSerializer):
    password_reset_form_class = ResetPasswordForm

    def get_email_options(self):
        return {
            'domain_override': settings.SITE_DOMAIN,
            'html_email_template_name': 'account/email/password_reset_key.html',
            'email_template_name': 'account/email/password_reset_key.txt',
        }

• 配置使用自定义序列化器
  在settings.py中添加以下配置：

REST_AUTH = {
    'PASSWORD_RESET_SERIALIZER': 'users.serializers.AllauthPasswordResetSerializer',
}

# 确保站点配置正确
SITE_ID = 1
SITE_DOMAIN = 'localhost:8000'

• 清理冲突路由
  移除urls.py中引用旧版Django auth路由的代码，避免路由冲突：

# 删除这两行：
# path('', include('django.contrib.auth.urls')),
# path('users/', include('django.contrib.auth.urls')),

• 验证效果
  重启服务后再次提交密码重置请求，控制台生成的链接将指向allauth的密码重置表单地址http://localhost:8000/accounts/password/reset/key/.../。

原理说明：通过替换dj-rest-auth的密码重置序列化器，使用allauth的ResetPasswordForm生成重置链接，该表单默认会调用allauth的路由地址，同时正确的站点配置能保证链接域名无误。
