I'm using Django 2.0, Django REST Framework and Django Filters to filter the queryset.
I have installed django-filters and added to INSTALLED_APPS as django_filters.
The settings file has
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': (
'oauth2_provider.contrib.rest_framework.OAuth2Authentication'
),
'DEFAULT_PERMISSION_CLASSES': [
'rest_framework.permissions.IsAuthenticated'
],
'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
'PAGE_SIZE': 10,
'DEFAULT_FILTER_BACKENDS': ('django_filters.rest_framework.DjangoFilterBackend',)
}
and the view class is like
class AmountGivenViewSet(viewsets.ModelViewSet):
serializer_class = AmountGivenSerializer
permission_classes = (IsAuthenticated,)
filterset_fields = ('contact__id',)
def get_queryset(self):
queryset = AmountGiven.objects.filter(
contact__user=self.request.user
)
query = self.request.query_params.get('q', None)
if query:
queryset = queryset.filter(
Q(transaction_number=query) |
Q(comment__contains=query) |
Q(amountreturned__transaction_number=query) |
Q(amountreturned__comment__contains=query)
)
return queryset
AmountGiven model has a foreign key to contact and thus want to filter based on contact_id.
Now when I try the following URL
https://example.com/api/amount-given/?contact__id=3634de36-181c-4414-93fc-f08e3d70f1e3
It does not filter the result and returns all AmountGiven records.
