NAME

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

VERSION

version 0.45

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.

• order_by

  This will be appended to the SQL which is generated to select the foreign rows. It should be an arrayref which can be passed to Fey::SQL::Select->order_by().

• 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 inherited from Fey::Meta::HasMany, it also provides the following methods:

$ho->fk()

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

$ho->order_by()

Corresponds to the value passed to the constructor.
