我正在使用 Django、django-allauth 和 django-invitations。我能够成功邀请用户加入该平台，但我想将他们与邀请者的公司关联起来。

我已经阅读了 bee-keeper/django-invitations，但似乎没有有关如何执行此操作的信息。

模型.py

class Company(models.Model):
    name = models.CharField(max_length=100, default=None)

class CustomUser(AbstractUser):
    company = models.ForeignKey(Company, on_delete=models.CASCADE, blank=True, null=True)
    objects = CustomUserManager()

views.py

@login_required
def company_users(request):
    # Get users that are in the company's user database as well as users that have been invited
    company_users = CustomUser.objects.filter(company=request.user.company.id)
    Invitations = get_invitation_model()
    # I'm afraid this is going to get all invited users, not just those that belong to the company
    invited_users = Invitations.objects.filter()

    if request.method == 'POST':
        print(request.POST)
        invitees = request.POST['invitees']
        invitees = re.split(',', invitees)
        for invitee in invitees:
            Invitation = get_invitation_model()
            try:
                invite = Invitation.create(invitee, inviter=request.user)
                invite.send_invitation(request)
            except IntegrityError as e:
                print(type(e))
                print(dir(e))
                return render(request, "company_users.html", {
                    'message': e.args,
                    'company_users' : company_users,
                    'invited_users' : invited_users,
                    })

    
    return render(request, 'company_users.html', {
        'company_users' : company_users,
        'invited_users' : invited_users,
    })

在上面的代码中，用户被成功邀请到平台，但该用户与邀请者的公司没有关联。我还担心受邀请的用户列表不限于用户的公司。

我必须在 django 中实现一个信号。它侦听用户注册，然后查看该用户是否在邀请模型中。如果是这样，它会查找邀请者的公司并将其与注册的用户关联起来。

init.py

default_app_config = "users.apps.UsersConfig"

信号.py

from allauth.account.signals import user_signed_up
from django.dispatch import receiver

from invitations.utils import get_invitation_model

@receiver(user_signed_up)
def user_signed_up(request, user, **kwargs):
    try:
        Invitation = get_invitation_model()
        invite = Invitation.objects.get(email=user.email)
    except Invitation.DoesNotExist:
        print("this was probably not an invited user.")
    else:
        user.company = invite.inviter.company
        user.save()
