無法保存到具有多個表的 Django 中的外鍵字段

Question

我正在開發一個項目人力資源管理系統。 我有一個 model 與辦公室和員工的外鍵字段。 我正在嘗試使用外鍵辦公室名稱明智地將員工保存在用戶和員工角色中。 我的觀點

def post(self, request):
    if request.method != "POST":
        messages.error(request, "Invalid Method ")
    else:
        first_name = request.POST.get('first_name')
        last_name = request.POST.get('last_name')
        username = request.POST.get('username')
        email = request.POST.get('email')
        password = request.POST.get('password')
        address = request.POST.get('address')
        phone = request.POST.get('phone')
        image = "image"
        office_id=request.POST.get("office")
        office=Office.objects.get(id=office_id)
    try:
        user = CustomUser.objects.create_user(username=username, password=password, email=email, first_name=first_name, last_name=last_name, user_type=2)
        user.staffs.address=address
        user.staffs.phone=phone
        user.staffs.image=image
        user.staffs.office_id=office
        user.save()
        messages.success(request, "Staff Added Successfully!")
        return render(request, 'admin_template/add_staff.html')

我的模型

class Staffs(models.Model):
    id = models.AutoField(primary_key=True)
    admin = models.OneToOneField(CustomUser, on_delete = models.CASCADE)
    address  = models.CharField(max_length=255, blank=True)
    phone = models.CharField(blank=True,max_length=20)
    image = models.ImageField(upload_to='uploads/user/',blank=True)
    office_id = models.ForeignKey(Office,on_delete=models.DO_NOTHING)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    objects = models.Manager()

@receiver(post_save,sender=CustomUser)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        if instance.user_type == 1:
            AdminHOD.objects.create(admin=instance)
        if instance.user_type == 2:
            Staffs.objects.create(admin=instance)
@receiver(post_save, sender=CustomUser)
def save_user_profile(sender, instance,**kwargs):
    if instance.user_type == 1:
        instance.adminhod.save()
    if instance.user_type == 2:
        instance.staffs.save()

此代碼在我的其他添加分支中工作

def post(self, request):
        if request.method != "POST":
            messages.error(request, "Invalid Method ")
        else:
            office_id = request.POST.get('company_name')
            office=Office.objects.get(id=office_id)
            branchName = request.POST.get('branch_name')
            phone = request.POST.get('phone')
            address = request.POST.get('address')
            email = request.POST.get('email')
            registrationNo = request.POST.get('registrationNo')
        try:
            branch = Branch(office_id=office, branchName=branchName, address=address, phone=phone, email=email)
            branch.save()
            messages.success(request, "Staff Added Successfully!")
            return render(request, 'admin_template/add_branch.html')

        except:
            messages.error(request, "Failed to Add Staff!")
            return render(request, 'admin_template/add_branch.html')

1. 我們可以從模型中刪除 (id)，因為它是自動實現的
2. office = models.ForeignKey(Office,on_delete=models.DO_NOTHING)
3. 像這樣將用戶員工辦公室分配到辦公室

user.staffs.office = office
