I have a few of these and generally use a variant of Simon's method where I
wrap everything in a custom class. I stash all the requirements/options in
the custom class instance, then invoke a `count()` or `paginated()` method
that builds/stashes the core query and runs `count()` or `all()` on it.
class CustomQuery():
_core_query = None
@property
def core_query(self):
if self._core_query is None:
# simon's code
self._core_query = XXX
return self._core_query
def count(self):
return self.core_query.count()
def paginated(self, offset=0, limit=None):
return self.core_query.offset(offset).limit(limit).
all()
