NAME ^

Asynapse::Record - Asynapse REST Model Client with API similar to ActiveRecord

VERSION ^

This document describes Asynapse::Record version 0.0.1

SYNOPSIS ^

    # Define Your own AsynapseRecord Class.
    package Person;
    use Moose;
    extends 'Asynapse::Record';
    has url_root => ( default => "http://localhost:3001" );
    has model => ( default => "person" );

    # Use it
    my $p = Person->find(1)

DESCRIPTION ^

This module uses similar interface as ActiveRecord to access your data. So far it has only 4 useful class methods: find, update, create, delete. The major difference between AsynapseRecord and other DBI abstraction layers are, in fact, AsynapseRecord isn't a DBD. It manipulate data on an http server using REST requests. It's a REST client that is specialized for manipulating data.

To use this module, define your own record class like this:

    package Person;
    use Moose;
    extends 'Asynapse::Record';
    has url_root => ( default => "http://localhost:3001" );
    has model => ( default => "person" );

You need to supply the default value of "url_root" and "model" in there. At this moment, the value of url_root should point to a Jifty instance with REST plugin installed. And the value of "model" should be the same name as one of those models in that Jifty instance.

The usage looks like this:

    my $p = Person->find(1)

At this moment, all methods listed below are class methods.

INTERFACE ^

new()

Object constructor. But so far it's not useful to you. So don't call it.

find( $id )

Retrieve a record from this model with primary key $id.

create( $attr )

Create a new with attributes specified in $attr hash ref.

update( $id, $attr )

Update the record with primary key $id with new sets of attributes specified in $attr hash ref.

delete( $id )

Remove the record with primary key $id.

url_root ( $url )

Get / set your Jifty instance's URL. You should set this in your own model class with this:

  has url_root => ( default => '...' );
model ( $model_name )

Get / set your associated model name in the Jifty instance. You should set this in your own model class with this:

  has model => ( default => '...' );

CONFIGURATION AND ENVIRONMENT ^

Asynapse requires no configuration files or environment variables. However, you need a Jifty instance with REST plugin (which is given by default now.)

DEPENDENCIES ^

Moose, LWP::UserAgent, JSON::Syck, and a Jifty instance that installs Jifty::Plugin::REST

INCOMPATIBILITIES ^

None reported.
