def become_vendor(request):
    # vendorform = VendorCreationForm()
    vendordetailform = VendorAdminDetailsForm()
    if request.method == 'POST':
        # vendorform = VendorCreationForm(request.POST)
        vendordetailform = VendorAdminDetailsForm(request.POST, request.FILES)

        
        if vendordetailform.is_valid():
        # if vendorform.is_valid():
            # new_user = vendorform.save()      
            print("hello")
            vendordetailform.instance.vendoruser = request.user
            print("hello1")
            request.user=vendordetailform.save()
            print("hello2")
            request.user.is_active = False
            request.user.save()
            user_details = CustomUser.objects.filter(id=request.user.id)
            vendor_details = user_details[0].vendor_details.all()
            return render(request,'vendor/preview.html', {'user_details':user_details, 'vendor_details':vendor_details})
    else:
        # vendorform = VendorCreationForm()
        vendordetailform = VendorAdminDetailsForm()

在这里，我在用户登录后将用户存储详细信息保存在外键相关模型中。在这里，我遇到了问题vendordetailform.instance.vendoruser = request.user。用户实例未存储，并且 user.is_active=False 没有发生。错误是Cannot assign "<SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at 0x00000158FEFB15B0>>": "VendorDetails.vendoruser" must be a "CustomUser" instance.
