So here you specify 'Asks' as all Ask objects associated with the current user.

Here you paginate all Ask objects, and don't do anything with pagination object.

And here you start using 'Asks' in the template as though it had been
paginated and was not a raw queryset. This is unlikely to work.
When you paginate a queryset, you need to create a paginator object
with that queryset, page the paginator to select an appropriate page,
and then pass the page to the template.
This is covered in mind numbing detail in the Django docs:
https://docs.djangoproject.com/en/1.4/topics/pagination/#using-paginator-in-a-view
