python - 无法保存到具有多个表的 Django 中的外键字段中

问题描述

我正在开发一个项目人力资源管理系统。我有一个模型，其中包含办公室和员工的外键字段。我正在尝试使用外键办公室名称明智地将员工保存在用户和员工角色中。我的观点

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()

解决方案

此代码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')
