Django-Rest-Framework 3.0 Field name '<field>' is not valid for model `ModelBase`

Question

Error message

I just tried out the Django-Rest-Framework 3.0 quick start guide (an excellent introduction by the way) and ran into this error when implementing it on my own system / table.

ImproperlyConfigured at /calls/ Field name `Datecreated` is not valid for model `ModelBase`. 

I quickly disassembled it and could not find anything, so I wanted to save this solution if someone else (who is also completely new) is faced with the same problem. I pasted the full code, since if you are stuck with this problem, you are probably a beginner and maybe you can use this to see how it all fits.

Table 'CallTraceAttempts'

  CallTraceAttemptId DateCreated ... 1 95352 2009-04-10 04:23:58.0000 2 95353 2009-04-10 04:24:08.0000 

the code

 ### models.py in the 'lifeline' app from __future__ import unicode_literals from django.db import models class CallTraceAttempts(models.Model): # Change these fields to your own table columns calltraceattemptid = models.FloatField(db_column='CallTraceAttemptId', blank=True, null=True, primary_key=True) # Field name made lowercase. datecreated = models.DateTimeField(db_column='DateCreated', blank=True, null=True) # Field name made lowercase. class Meta: managed = False # I don't want to create or delete tables db_table = 'CallTraceAttempts' # Change to your own table ### urls.py from django.conf.urls import patterns, include, url from lifeline.models import CallTraceAttempts # Change to your app instead of 'lifeline' from rest_framework import routers, serializers, viewsets # Serializers define the API representation class CallTraceAttemptsSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = CallTraceAttempts fields = ('calltraceattemptid', 'Datecreated') # ViewSets define the view behavior class CallTraceAttemptsViewSet(viewsets.ModelViewSet): queryset = CallTraceAttempts.objects.all() serializer_class = CallTraceAttemptsSerializer # Routers provide an easy way of automatically determining the URL conf router = routers.DefaultRouter() router.register(r'calls', CallTraceAttemptsViewSet) urlpatterns = patterns('', url(r'^', include(router.urls)), url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')) )

Explanation

So the problem arises here under the urls.py fields. Make sure that the fields in your serializer exactly match (case sensitive) with the field on your models.py.

 ### urls.py #... # Serializers define the API representation class CallTraceAttemptsSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = CallTraceAttempts fields = ('calltraceattemptid', 'datecreated') ### Issue was right here, earlier version had 'Datecreated'
