Basic Mapping

The mapping is done with the config classes.

Connection

You can define explicitly the connection in the documents. Otherwise the default connection of the mandango will be used:

array(
    'Model\Article' => array(
        // defining explicitly the connection
        'connection' => 'global',
    ),
    'Model\Author' => array(
        // another explicitly connection
        'connection' => 'local',
    ),
    'Model\Category' => array(
        // nothing, default connection
    ),
);

Collection

You can also define explicitly the collection where the documents are saved in, and if you don’t, the CamelCase name of the documents class will be used for that:

array(
    'Model\Article' => array(
        // defining explicitly the connection
        'collection' => 'articles',
        'fields' => array(
            'title' => 'string',
        ),
    ),
);

Types

Mandango has types to allow map data between PHP and Mongo.

• bin_data
• boolean
• date
• float
• integer
• raw
• serialized
• string

You can also define custom types. We’ll see how later.

Fields

The fields are the data of the documents, the same as in Mongo.

To define the fields you have to indicate the type:

array(
    'Model\Article' => array(
        'fields' => array(
            // as string
            'title' => 'string',
            // as array
            'content' => array('type' => 'string'),
        ),
    ),
);

You can define also options in the fields.

Default Value

If you want you can use default values:

array(
    'Model\Article' => array(
        'fields' => array(
            'is_active' => array('type' => 'boolean', 'default' => true),
        ),
    ),
);

Database Field

You can change the field in which the data is saved in the database. Thus you can use a different field name in PHP and Mongo:

array(
    'Model\Article' => array(
        'fields' => array(
            'php_field_name' => array('type' => 'string', 'db_name' => 'mongo_field_name'),
        ),
    ),
);

These are the options the Mandango’s Core extension accepts, but you can use more options depending on the extensions you use.

Note

You can define as fields as you want to take advantage of the Mongo free schema. Mandango has been designed thinking in that, and to define lots of fields is not a performance problem.
