NAME

DBIx::Class::Relationship::Predicate - Predicates for relationship accessors

VERSION

version 0.07

SYNOPSIS

package My::Schema::Result::Foo;

__PACKAGE__->load_components(qw( Relationship::Predicate ... Core ));

...

__PACKAGE__->belongs_to('baz' => 'My::Schema::Result::Baz',  'baz_id');

__PACKAGE__->might_have(
    'buzz' => 'My::Schema::Result::Buzz',
    { 'foreign.foo_id' => 'self.id' },
    { 'predicate' => 'got_a_buzz' },
);

__PACKAGE__->has_many(
    'foo_baz' => 'My::Schema::Result::FooBaz',
    { 'foreign.foo_id' => 'self.id' },
    { 'predicate' => undef },
);

__PACKAGE__->has_many('bars' => 'My::Schema::Result::Bar', 'foo_id');

1;

DESCRIPTION

DBIx::Class component to automatically create predicates for relationship accessors in a result class. By default, it creates "has_${rel_accessor_name}" methods and injects into the class, thus for that case we would have 'has_baz', 'has_buzz' and 'has_bars' methods on $foo row object. You can define the name for each one (or also disable its creation using undef as value) by setting 'predicate' key in the relationship's attrs hashref.

__PACKAGEE_->might_have(
    'buzz' => 'My::Schema::Result::Buzz', 'foo_id',
    { 'predicate' => 'got_a_buzz' }
);

or

__PACKAGEE_->might_have(
    'buzz' => 'My::Schema::Result::Buzz', 'foo_id',
    { 'predicate' => undef }
);
