MongoDB

Lodata supports read, update, create, delete, and query operations, and has extensive support for filters on an attached MongoDB collection.

Discovery

A MongoDB Collection can be discovered using Lodata::discover($collection);.

For example this code will generate a MongoEntitySet with an associated MongoEntityType and register them with the model. The EntityType and EntitySet will be automatically created singular/plural respectively.

class LodataServiceProvider extends ServiceProvider
{
    public function boot()
    {
        $client = new \MongoDB\Client;
        \Lodata::discover($client->db->users);
    }
}

Type extension

The MongoEntityType provides an entity type starting point, with the key property _id set to an Edm.String key.

This entity type is an open type by default, which means you do not have to declare any additional properties on the type to use it with Lodata. However, adding declared properties will make your data model more discoverable, so this is recommended if possible. This can be performed either after discovery, or when manually defining your type.

This is an example of manually creating the type and set:

class LodataServiceProvider extends ServiceProvider
{
    public function boot()
    {
        $entityType = new \Flat3\Lodata\Drivers\MongoEntityType('User');
        $entityType->addDeclaredProperty('name', \Flat3\Lodata\Type::string());

        $entitySet = new \Flat3\Lodata\Drivers\MongoEntitySet('Users', $entityType);

        $client = new \MongoDB\Client;
        $entitySet->setCollection($client->db->users);

        \Lodata:add($entitySet);
    }
}
