Is this the best way to setup your relationships if you want the
ability to check if there is one there? I have a 'one to one'
relationship, which i guess in my case is more a 'one to maybe one or
maybe none' relationship. So if I do:
$foo->bar
Just to check if the relation exists, it gives a fatal error by
default. If I do soft => 1 then i can stop it croaking. But this sort
of tells Rose (and people looking at my code) that I haven't bothered
to setup referential_integrity. Even though I have.
create table foo (
id serial not null,
foo text,
primary key (id)
);
create table bar (
foo_id int references foo(id),
bar text,
primary key (foo_id)
);
create table baz (
foo_id int references foo(id),
baz text,
primary key (foo_id)
);
So if I load() foo object, there may be a bar object linking back to
it, but there might not.
$foo = Foo->new(id => 1);
$foo->load;
if ($foo->bar) {
print $foo->bar->bar;
}
if ($foo->baz) {
print $foo->baz->baz;
}
As I said above, soft => 1 fixes it just fine. I'm just checking to
make sure that's the best approach, or am I sort of lying to Rose by
telling it these are 'one to one' relationships and i am not usinf
ref integ.
