在注册 allauth Django 时处理 IntegrityError

如何解决在注册 allauth Django 时处理 IntegrityError

我正在使用 Django allauth 进行 google 用户注册和登录。现在，我想为每个尝试注册的用户提供唯一的电子邮件地址，无论是通过 google 还是普通的 django 注册。

对于独特的电子邮件，我在 models.py

中编写了以下内容

User._Meta.get_field('email')._unique = True

这工作得很好，但通过谷歌登录注册时出现问题。

settings.py

    'django.contrib.admin','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles','django.contrib.humanize','django_filters','django.contrib.sites','allauth','allauth.account','allauth.socialaccount','allauth.socialaccount.providers.google','crispy_forms',]

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware','django.contrib.sessions.middleware.SessionMiddleware','django.middleware.common.CommonMiddleware','django.middleware.csrf.CsrfViewMiddleware','django.contrib.auth.middleware.AuthenticationMiddleware','django.contrib.messages.middleware.MessageMiddleware','django.middleware.clickjacking.XFrameOptionsMiddleware',]

AUTHENTICATION_BACKENDS = [

    # Needed to login by username in Django admin,regardless of `allauth`
    'django.contrib.auth.backends.ModelBackend',# `allauth` specific authentication methods,such as login by e-mail
    'allauth.account.auth_backends.AuthenticationBackend',]

我只想处理异常。提前致谢
