Oops, it seems I accidentally overwrote my original question, instead of replying to it. Sorry. Anyway, the question was how to determine the number of rows in a DBIx::Class::ResultSet object from within TT2.

I have found the solution myself:

[%# set the variable objects to an array of 0 or more objects, taken f
+rom user.objects, which is a DBIx::Class::ResultSet %]
[% IF user.objects %]
  [% IF user.objects.0 %]
    [% SET objects = user.objects %]
  [% ELSE %]
    [% SET objects = [ user.objects ] %]
  [% END %]
[% ELSE %]
  [% SET objects = [] %]
[% END %]

Number of objects: [% objects.size %]

Unfortunately, it is not possible to write a macro for this, because TT macros can't return results...
