NAME

Fey::Meta::HasOne::ViaFK - A parent for has-one metaclasses based on a Fey::FK object

VERSION

version 0.47

DESCRIPTION

This class implements a has-one relationship for a class, based on a provided (or deduced) Fey::FK object.

CONSTRUCTOR OPTIONS

This class accepts the following constructor options:

  • fk

    If you don't provide this, the class looks for foreign keys between $self->table() and and $self->foreign_table(). If it finds exactly one, it uses that one.

  • allows_undef

    This defaults to true if any of the columns in the local table are NULLable, otherwise it defaults to false.

METHODS

Besides the methods provided by Fey::Meta::Role::Relationship::HasOne and Fey::Meta::Role::Relationship::ViaFK, this class also provides the following methods:

$ho->fk()

Corresponds to the value passed to the constructor, or the calculated default.
