Question

当我使用Django REST框架时，使用Use OneToOneField和RetrieveUpdateDestroyAPIView不能通过pk获取; 我的代码如下：

models.py

class UserAccount(models.Model):
    username = models.CharField(null=False, max_length=45) 
    password = models.CharField(null=False, max_length=16) 

class UserContactInfo(models.Model):
    userAccount = models.OneToOneField(UserAccount, primary_key=True)
    phone_number = models.CharField(null=True, blank=True)
    email = models.CharField(null=True, blank=True, max_length=45)

serializers.py

class UserAccountSerializer(serializers.ModelSerializer):
    class Meta:
        model = UserAccount
        fields = ('id', 'username', 'password')


class UserContactInfoSerializer(serializers.ModelSerializer):
    class Meta:
        model = UserContactInfo
        fields = ('userAccount', 'phone_number', 'email')

views.py

class UserContactInfoDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = UserAccount.objects.all()
    serializer_class = UserContactInfoSerializer

urls.py

urlpatterns = [
    ...
    url(r'^ContactInfo/(?P<pk>[0-9]+)/$',    views.UserContactInfoDetail.as_view()),
    ]

好的，当我尝试获取UserContactInfo数据时：

GET http://127.0.0.1:8000/ContactInfo/1/

出错了：

AttributeError at /ContactInfo/1/
'UserAccount' object has no attribute 'userAccount_id'

Request Method: GET
Request URL: http://127.0.0.1:8000/ContactInfo/1/
.....

谁能帮我解决问题。谢谢！

我认为你在查询集中有拼写错误：
queryset = UserAccount.objects.all()代替UserContactInfo.objects.all()

Django REST框架：使用OneToOneField无法获取
