you better use bool(user.groups.filter(name=EX_GROUP_NAME)), count is unnecessary here ( nonzero is overloaded for querysets) and count is slow on transactional storages.

buriy (on September 7, 2009):

or just "if user.groups.filter(name=EX_GROUP_NAME)" :)

david_bgk (on September 8, 2009):

".count()" is faster but I agree that it can be tested directly in the "if" ;)

I edited it to do the test in the "if" directly. Slightly less obvious code to me, now, but shrug.
