Checking for empty queryset in Django

Question

What is the recommended idiom for checking whether a query returned any results?
Example:

orgs = Organisation.objects.filter(name__iexact = \'Fjuk inc\')         


        

Answer 1

I disagree with the predicate

if not orgs:

It should be

if not orgs.count():

I was having the same issue with a fairly large result set (~150k results). The operator is not overloaded in QuerySet, so the result is actually unpacked as a list before the check is made. In my case execution time went down by three orders.
