我一直在接受 'Options'对象没有属性'get_all_related_objects'错误。我研究过,人们说使用旧版django经常是一个问题,但我使用的是1.11.6
当我导航到url:app / employees时,我收到此错误。
我做错了什么?
Django Version: 1.11.6
Exception Type: AttributeError
Exception Value:
'Options' object has no attribute 'get_all_related_objects'
其他版本号:
应用/型号:
class Employee(models.Model):
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)
supervisor = models.ForeignKey('self', blank=True, null=True)
is_active = models.BooleanField(default=True)
is_supervisor = models.BooleanField(default=False)
class Meta:
ordering = ('last_name',)
def __str__(self):
return "{}".format(self.first_name + ' ' + self.last_name)
应用程序/串行化器:
class EmployeeSerializer(serializers.ModelSerializer):
class Meta:
model = Employee
应用程序/ api.py:
class EmployeeApi(ListAPIView):
queryset = Employee.objects.all()
serializer_class = EmployeeSerializer
应用程序/ url.py
urlpatterns = [
...
url(r'^employees$', EmployeeApi.as_view()),
]

Django v1.11 support is not added for django-rest-framework
until version 3.7。升级django-rest-framework
应该可以解决问题。
升级django-rest-framework,pip install -U djangorestframework
