Rounding values can be done with:
{{{
from django.db.models.functions import Round
Round(Count('related_model'))
}}}
But we could also implement the __round__ function on the Expression
class, and thus use Python's round(...) function, then it thus no longer
requires an import:
{{{
round(Count('related_model'))
}}}
A potential problem with this is that people might expect that this will
itself return a number-like object, and not an expression.
