from your_app.serializers import YourModelSerializer
from rest_framework.permissions import IsAuthenticated

class YourView(DjeasyListCreateView):
    model = YourModel
    list_serializer_class = YourModelSerializer
    create_serializer_class = YourModelSerializer
    serializer_class = YourModelSerializer
    queryset = YourModel
    select_related = ['key1' , 'key2']
    prefetch_related = ['key1' , 'key2']
    permission_classes = [IsAuthenticated]
    enable_cache = True
    cache_duration = 60
    query_params = {
        "name": "name",
        "related_field__id": "related_id",
        "related_field__name": "related_name",
    }
    pagination = True

DjeasyModelSerializer.options(

    queryset=UserModel.objects.all(),
    fields="__all__",
    many=True,
    display_fields={"id","name","email","password","profile"},
