Django REST框架：使用OneToOneField不能GET

Question

当我使用Django REST框架，并使用Use OneToOneField和RetrieveUpdateDestroyAPIView无法通过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()), 
    ] 

好吧，当我试图让UserContactInfo数据：

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

和出错：

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

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

谁能帮我解决它。谢谢！

我想你在视图中有错字，在查询集：中
queryset = UserAccount.objects.all()代替UserContactInfo.objects.all()
