Allow Paginator to Support Non QuerySets

[germish@…]

I write quite a few Custom SQL queries. In addition, I like the built in paginator package that django provides. The problem is that paginator.py asks for a QuerySet, when all it uses a QuerySet for is to query_set.count(). Anyways, my point is... paginator.py should allow for queries returned by cursor.fetchall() (and similar). It's already so generic that this tiny patch provides this enhancement:

/django/core/paginator.py

def _get_hits(self):
    if self._hits is None:
        try:
            self._hits = self.query_set.count()
        except:
            self._hits = len(self.query_set)
    return self._hits

All I added was the try-except block to default to len(self.query_set) if .count() fails

My patch in #2093 fixes this and more! :)

It is still waiting to be applied (or at least critiqued).
