An arrayref containing a list of accessors in the foreign class to proxy in
the main class. If, for example, you do the following:
-
+
CD->might_have(liner_notes => 'LinerNotes', undef, {
proxy => [ qw/notes/ ],
});
-
+
Then, assuming LinerNotes has an accessor named notes, you can do:
my $cd = CD->find(1);
=item accessor
Specifies the type of accessor that should be created for the
-relationship. Valid values are C<single> (for when there is only a single
-related object), C<multi> (when there can be many), and C<filter> (for
-when there is a single related object, but you also want the relationship
-accessor to double as a column accessor). For C<multi> accessors, an
-add_to_* method is also created, which calls C<create_related> for the
+relationship. Valid values are C<single> (for when there is only a single
+related object), C<multi> (when there can be many), and C<filter> (for
