I'm currently having trouble with writing Django Rest Framework filtering data by url. For some reason the problem seems to be when I import my views. The error points to the models which was working fine before I added the url filter in urls.py

File "/home/jd_dhang/drf-demo/project/urls.py", line 5, in <module>

    from apps.core.views import SurgeryView

  File "/home/jd_dhang/drf-demo/project/apps/core/views.py", line 2, in <module>

    from .models import University, Student, SurgeryType

  File "/home/jd_dhang/drf-demo/project/apps/core/models.py", line 3, in <module>

    class University(models.Model):

  File "/home/jd_dhang/drf-demo/venv/lib/python3.5/site-packages/django/db/models/base.py", line 102, in __new__

    "INSTALLED_APPS." % (module, name)

RuntimeError: Model class apps.core.models.University doesn't declare an explicit app_label and isn't in an applica

tion in INSTALLED_APPS.

Django==1.9.13, djangorestframework==3.6.0

project/urls.py

**from apps.core.views import SurgeryView**



urlpatterns = [

    **url(r'^api/surgery/(?P<surgery_type>.+)/$', SurgeryView.as_view())**,

    ...

]

project/apps/core/views.py

from rest_framework import viewsets

from .models import University, Student, SurgeryType

from .serializers import UniversitySerializer, StudentSerializer, SurgeryTypeSerializer



class StudentViewSet(viewsets.ModelViewSet):

...

class UniversityViewSet(viewsets.ModelViewSet):

...



class SurgeryView(viewsets.ModelViewSet): #(APIView):

    queryset = SurgeryType.objects.all()

    serializer_class = SurgeryTypeSerializer

    def get_queryset(self):

        queryset = SurgeryType.objects.all()

        surgery_type = self.kwargs['surgery_type']

        return SurgeryType.objects.filter(surgery_type=surgery_type)

Here are my models if it helps

project/apps/core/models.py

from django.db import models



class University(models.Model):

    name = models.CharField(max_length=50)



    class Meta:

        verbose_name = "University"

        verbose_name_plural = "Universities"



    def __str__(self):

        return self.name



class Student(models.Model):

    first_name = models.CharField(max_length=50)

    last_name = models.CharField(max_length=50)

    university = models.ForeignKey(University)



    class Meta:

        verbose_name = "Student"

        verbose_name_plural = "Students"



    def __str__(self):

        return '%s %s' % (self.first_name, self.last_name)



class SurgeryType(models.Model):

    surgery_type = models.CharField("surgery_type", max_length=200)

    sub_type = models.IntegerField(default=1)

    available = models.BooleanField()

    url = models.URLField(max_length=200, default='https://www.google.com')



    def __str__(self):

        return 'Type: ' + self.surgery_type + ' SubType : ' + str(self.sub_type)

Thank you

Fix the import in your urls.py.

It should be from core.views import SurgeryView instead of from apps.core.views import SurgeryView
