NAME

Mongoose - MongoDB document to Moose object mapper

VERSION

version 0.05

SYNOPSIS

package Person;
use Moose;
with 'Mongoose::Document';
has 'name' => ( is => 'rw', isa => 'Str' );

package main;
use Mongoose;

Mongoose->db('mydb');
my $person = Person->new( name => 'Jack' );
$person->save;

my $person = Person->find_one( { name => 'Jack' } );
say $person->name;    # Jack

my $cursor = Person->find( { name => 'Jack' } );
die "Not found" unless defined $cursor;
while ( my $person = $cursor->next ) {
    say "You're " . $person->name;
}

$person->delete;

DESCRIPTION

This is a MongoDB to Moose object mapper. This module allows you to use the full power of MongoDB within your Moose classes, without sacrificing MongoDB's power, flexibility and speed.

It's loosely inspired by Ruby's MongoMapper, which is in turn loosely based on the ActiveRecord pattern.

Start by reading the introduction Mongoose::Intro.

Or proceed directly to the Mongoose::Cookbook for many day-to-day recipes.

METHODS

db

Sets the current MongoDB connection and/or db name.

Mongoose->db( 'myappdb' );

The connection defaults to whatever MongoDB defaults are (typically localhost:27017).

For more control over the connection, db takes the same parameters as MongoDB::Connection, plus db_name.

my $db = Mongoose->db(
    host          => 'mongodb://localhost:27017',
    query_timeout => 60,
    db_name       => 'myapp'
);

This will, in turn, instantiate a MongoDB::Connection instance with all given parameters and return a MongoDB::Database object.

load_schema

Uses Module::Pluggable to require all modules under a given search path or search dir.

All arguments will be sent to Module::Pluggable's import, except for Mongoose specific ones.

package main;
use Mongoose;

# to load a schema from a namespace path:
Mongoose->load_schema( search_path=>'MyApp::Schema' );

This method can be used to shorten class names, aliasing them for convenience if you wish:

Mongoose->load_schema( search_path=>'MyApp::Schema', shorten=>1 );

Will shorten the module name to it's last bit:

MyApp::Schema::Author->new( ... );

# becomes

Author->new( ... );

naming

By default, Mongoose composes the Mongo collection name from your package name by replacing double-colon :: with underscores _, separating camel-case, such as aB with a_b and uppercase with lowercase letters.

This method let's you change this behaviour, by setting setting the collection naming default sub.

The closure receives the package name as first parameter and should return the collection name.

# let me change the naming strategy
#  for my mongo collections
#  to plain lowercase

Mongoose->naming( sub { lc(shift) } );

connection

Sets/returns the current connection object, of class MongoDB::Connection.

Defaults to whatever MongoDB defaults.

BUGS

This is a WIP, barely *beta* quality software.

Report bugs via RT. Send me test cases.

TODO

* Better error control

* Finish-up multiple database support

* Allow query->fields to control which fields get expanded into the object.

* Cleanup internals.

* More tests and use cases.

* Better documentation.
