我正在尝试使 Django 组织的自定义邀请工作。但它抛出了一个错误。我找不到原因。下面是我的代码：

我的urls.py档案

from django.urls import path, include
from organizations.backends import invitation_backend

urlpatterns = [
    path('accounts/', include('organizations.urls')),
    path('invitations/', include(invitation_backend().get_urls())),
]

在我的settings.py文件中，我在已安装的应用程序部分添加了“组织”应用程序和我的自定义应用程序“集成”。需要在以下链接中为自定义邀请添加后端：https ://django-organizations.readthedocs.io/en/latest/custom_usage.html#creating-the-backend

这是指定的后端。

INVITATION_BACKEND = 'integration.backends.CustomInvitations'

我的backends.py档案

from organizations.backends.defaults import InvitationBackend


class CustomInvitations(InvitationBackend):
    def invite_by_email(self, email, sender=None, request=None, **kwargs):
      try:
          user = self.user_model.objects.get(email=email)
      except self.user_model.DoesNotExist:
          user = self.user_model.objects.create(email=email,
                  password=self.user_model.objects.make_random_password())
          user.is_active = False
          user.save()
      self.send_invitation(user, sender, **kwargs)
      return user

这是发生的错误：

几分钟前，我自己刚刚遇到了这个错误。该错误告诉您它正在尝试使用配置的 SMTP 服务器发送电子邮件，但机器拒绝连接。短版 - 您需要指向一个正在运行的 SMTP 服务器。

我无法找到指向远程 SMTP 服务器的正确设置，但我能够做的是运行本地假 SMTP 服务器以消除错误并至少让该过程运行完成。

我通过安装和运行nullsmtpd做到了这一点。

使用以下命令安装包：

pip install nullsmtpd

创建一个文件夹来存储电子邮件和日志：

mkdir email

在 Windows 上启动该过程并将其指向您的输出文件夹：

nullsmtpd --mail-dir email --no-fork

侦听器默认为端口 25 上的 localhost，这与您的 Django 应用程序应使用的默认 SMTP 设置一致。
