a) You don't need to use getattr when you know what attr you are
trying to get, those getattr calls can be changed to mgr.filter
b) filter works using kwargs, kwargs work like dictionaries so you can
just create a dictionary and then in the method call do
**dictionary_var to have it called with that dict as the kwargs, for
example:
In [2]: filter = {'title__icontains': 'test'}
In [3]: Page.objects.filter(**filter)
Out[3]: [<Page: This is a test page: I have some content here to
appropriately fill up a test page quite a bit, just need a little
more, >]
In [4]: var = 'title__icontains'
In [5]: filter = {var: 'test'}
In [6]: Page.objects.filter(**filter)
Out[6]: [<Page: This is a test page: I have some content here to
appropriately fill up a test page quite a bit, just need a little
more, >]
