Hello Alex,
the simple hashref-type defintion expects a pair of column names.
I did the same thing using the coderef-type definition. For an example
see
https://github.com/dboehmer/coocook/blob/c9b3503f3df44a6817c5402225913815849e4aaa/lib/Coocook/Schema/Result/Unit.pm#L38
Beware that with a coderef you cannot simply write the name of
the column to be equal but now you actually need to say the
column should be equal to the value of a given column (-ident).
You'll need something like this:
sub {
my $args = shift;
return {
"$args->{foreign_alias}.agreement" => { -ident =>
"$args->{self_alias}.id" },
"$args->{foreign_alias}.bill" => undef,
};
}
Does that work?
Kind regards
Daniel

Hello
I'm trying to make left join with extra condition
agreements a left join bill_mails bm on a.id = bm.agreement and
bm.bill is null
However,
{ "foreign.agreement" => "self.id",
"foreign.bill" => undef
},
yields error
Could not load Schema Class (Billing::Schema).
DBIx::Class::ResultSource::add_relationship(): Malformed relationship
condition value '': must be prefixed with 'self.'
Is it possible to make such a clause without extra view?
