One fairly normal solution is to write a method that returns the results
you want (in a format you can use). For example, you're passing in "s"
as an argument to a method on "s", which is usually redundant. So you
can write a method that works on "self" there by default. And that
method could also know that it should work with "Person" (whatever that
is). So, it's a custom method for this case.
Alternatively, if the method is purely presentational and not
particularly related to whatever object "s" is, write a filter function.
Filters can take arguments. So something like:
{% for v in s|getStats:"person" %}
That way, the getStats() function is divorced from s, but it takes "s"
and "person" as two arguments.
