you having , after name of bdetail model in bdetailserializer serializer. remove , code work.

suggestion: inherit serializers.modelserializer in bdetailserializer serializer instead of serializers.hyperlinkedmodelserializer i.e. :

class bdetailserializer(serializers.modelserializer):     class meta:         model = bdetail         fields = ('lat', 'lng')
