I needed to annotate something to a queryset and found a solution that
looked like this:
{{{
queryset = MyModel.objects.annotate(
created_less_than_hour_ago=Q(time_of_creation__gt=(now() -
timedelta(hours=1)))
)
}}}
It worked fine and "created_less_than_hour_ago" was set to True if the
object was created less than an hour ago and to False otherwise. I found
another way to achieve this though because I didn't find any documentation
about the use of Q objects inside of the annotate method, so I couldn't
understand why and how it worked.
So, here I am asking for documentation about it.
