通过ID得到的是在Django /夹层产生错误

Question

def check(request): 
     if request.user.is_authenticated: 
     uid = request.user.id 
     if AllUsers.objects.get(FK_id = uid): 
      return True 
     else: 
      return False 

错误：在DoesNotExist /用户/ AllUsers的匹配查询不存在的。

如何解决这个错误？

from django.db import models 
from django.contrib.auth.models import User 
from mezzanine.pages.models import Page 
# The members of Page will be inherited by the Author model, such 
# as title, slug, etc. For authors we can use the title field to 
# store the author's name. For our model definition, we just add 
# any extra fields that aren't part of the Page model, in this 
# case, date of birth. 

GENDER = (('male','Male'), ('female','Female')) 
class AllUsers(models.Model): 
    FullName = models.CharField(max_length=300) 
    DOB = models.DateField() 
    Gender = models.CharField(max_length=7, choices = GENDER) 
    HomeAddress = models.TextField() 
    Contact = models.CharField(max_length=300) 
    Email = models.EmailField() 
    FK = models.ForeignKey(User)

你不应该;吨使用_id属性检索通过外键连接模型。 而是执行此操作：

user = models.ForeignKey(User) 

而且，在你看来：

object_AllUsers = AllUsers.objects.get(user = request.user) 

此外，您可能需要使用一个OneToOneField，而不是ForeignKey的。 查看更多关于这里：https://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.ForeignKey
