我有一个如下所示的模型：
class StaffProfile(models.Model):
user = models.ForeignKey(User)
maas = models.FloatField()
maas_gunu = models.CharField(max_length=5)
当我尝试使用如下代码插入数据时：
staffprofilesay = StaffProfile.objects.filter(user = user_id).count()
if staffprofilesay > 0:
staffprofile = StaffProfile.objects.get(user = user_id)
else:
staffprofile = StaffProfile()
staffprofile.user = user_id
staffprofile.maas = calisan_formu.cleaned_data["maas"]
staffprofile.maas_gunu = calisan_formu.cleaned_data["maas_gunu"]
staffprofile.save()
我得到如下错误：
Cannot assign "u'1'": "StaffProfile.user" must be a "User" instance.
我应该做些什么？
PS：我正在使用Django的用户模型
解决方法
您需要分配一个User对象,例如
from django.contrib.auth.models import User user = User.objects.get(id=user_id) staffprofile.user = user
