NAME

PONAPI::DAO::Repository - Interface role for PONAPI::DAO repositories

VERSION

version 0.001005

SYNOPSIS

package My::PONAPI::Repository {
    use Moose;
    with 'PONAPI::DAO::Repository';

    sub has_type { ... }

    ...
}

Clases implementing repositories for PONAPI::DAO must consume the PONAPI::DAO::Repository role; this ensures that the methods required by the DAO to fullfil the implementation are all present.

The arguments that each method can receive are expanded on in PONAPI::DAO; some differences are explained below. Keep in mind that, with the exceptions of the has_* methods, all methods will receive a document argument, which is always an instance of PONAPI::Builder::Document, but not necessarily a new instance.

$obj->has_type( $type )

Must return true if the repository handles $type

$obj->has_relationship( $type1, $type2 )

Must return true if $type1 has a relationship to $type2.

# Do articles have comments?
$obj->has_relationship('articles', 'comments');

$obj->has_one_to_many_relationship($type1, $type2)

Must return true if $type1 has a relationship to $type2, and that relationship is one-to-many.

retrieve

retrieve_all

retrieve_relationships

retrieve_by_relationship

create

data will be an arrayref of resources.

delete

update

Return value MUST be one of the PONAPI_UPDATE_* constants provided by PONAPI::DAO::Constants, like PONAPI_UPDATED_EXTENDED.

If the update operation updated more than what was requested (for example, an updated column in the table, and that column is part of the resource), then it must return PONAPI_UPDATED_EXTENDED; if the update on the primary resource did nothing, then it must return PONAPI_UPDATED_NOTHING. In all other non-error situations, it must return PONAPI_UPDATED_NORMAL instead.

update_relationships

See "update".

data will be either undef, a hashref, or an arrayref, depending on what sort of relationship the request is trying to update.

delete_relationships

See "update".

data will be an arrayref of resources.

create_relationships

See "update".

data will be an arrayref of resources.
