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：/ users /中的DoesNotExist 匹配查询的AllUsers不存在。

如何解决此错误？

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)

Answer 1

您不应该使用_id属性来检索通过外键连接的模型。这样做：

user = models.ForeignKey(User)

并且，在您看来：

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

此外，您可能希望使用OneToOneField而不是ForeignKey。点击此处了解详情：https://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.ForeignKey
