Oh, and this will work, almost. You don't need the "->all". The
has_many('bars') relation creates a 'bars' method on each Foo Result object:
foreach my $r_bar (map { $_->bars } $rs_foo->all) {
$r_bar->some_method;
}
For speed, prefetch bars.

If I was developing the schema, in addition to the relation you show, in
Result::Bar I'd have:
__PACKAGE__->belongs_to('foo', 'MyApp::Schema::Result::Foo', { ... });
Then search for all the bars with a particular foo (you use the name of the
relation, not the table) property:
foreach my $r
Hello,
And one more question, if anyone doesn't mind. :-)
Is there an elegant way to apply a Result's method to the whole ResultSet?
In other words, here's what I have to do:
# MyApp::Schema::Result::Foo->has_many('bars',
'MyApp::Schema::Result::Bar', { ... });
my $rs_foo = $sch

Thank you very much, it's exactly what I've been looking for!

Hello,
Is that possible to merge multiple ResultSets into one? For example, I’ve got 3
different ResultSets (as the yields of 3 different SQL-queries), but I’m pretty
sure that they are based on the same class. Yes, I can work with their Results
as with elements of a list, but sometimes it woul
