Hi,
I am using DRF with no Django models, the reason is a legacy database that
has limited connection options (pyodbc only). I was hoping somebody could
help me figure out how to get the browsable API HTML controls for
pagination working.
What I have now is a subclassed GenericViewSet implementing list, along
with a custom serializer, custom database layer, and custom paginator:
class MyPaginator(LimitOffsetPagination):
def paginate_queryset(self, queryset, request, view=None):
self.limit = self.get_limit(request)
if self.limit is None:
return None
self.offset = self.get_offset(request)
self.count = queryset.count()
self.request = request
if self.count > self.limit and self.template is not None:
self.display_page_controls = True
if self.count == 0 or self.offset > self.count:
return []
#Add the limit/offset to the query
if self.limit:
queryset = queryset.limit(self.limit)
if self.offset:
queryset = queryset.offset(self.offset)
return list(queryset.execute())
from project.pagination import MyPaginator
from project.serializers import MySerializer
class MyViewSet(GenericViewSet):
serializer_class = MySerializer
pagination_class = MyPaginator
def get_queryset(self):
#Get the objects from the legacy DB
return Database().table("customers").all()
def list(self, request):
#Get the queryset (not a django queryset)
queryset = self.get_queryset()
#Run it through the paginator
paginator = pagination_class()
objects = paginator.paginate_queryset(queryset , request)
#Serialize the list of objects
serializer = self.serializer_class(objects, many=True)
#return Response(serializer.data)
return paginator.get_paginated_response(serializer.data)
This actually works well and the browsable API shows paginated data with
links to the next page. What I don't get is the HTMl pagination controls.
The docs say to set display_page_controls as True, but it is and no luck.
Anybody ever tried this, or have any ideas where I should look?
Thanks,
Angus
