    "require": {
       "qeti/simple-podata": ">=0.9.1"
    }

Run composer update afterwards.

Usage

In your basic Yii2 project

Add the following to the configuration file web.php:

    'components' => [
        'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
                ['class' => 'qeti\Yii2PODataAdapter\ODataUrlRule'],
            ],
        ],
    ],
    'controllerMap' => [
        'o-data' => 'qeti\Yii2PODataAdapter\implementation\ODataController',
    ],

Set up class map for MetaProvider:

yii::$classMap['qeti\Yii2PODataAdapter\implementation\MetadataProvider'] = '@app/models/OData/MetadataProvider.php';

Create classes, what describe entities, for example:

namespace app\models\OData\Entities;

use yii\db\ActiveRecord;
use qeti\SimplePOData\EntityTrait;

class Request extends ActiveRecord {

    use EntityTrait;

    public $id;
    public $type_code;
    public $status_code;
}

Create MetaProvider class, what describe all entities for POData, for example:

namespace qeti\Yii2PODataAdapter\implementation;

use POData\Providers\Metadata\Type\EdmPrimitiveType;
use POData\Providers\Metadata\SimpleMetadataProvider;

class MetadataProvider
{
    const MetaNamespace = "Data";

    /**
     * @return IMetadataProvider
     */
    public static function create()
    {
        $metadata = new SimpleMetadataProvider('Data', self::MetaNamespace);

        $requestEntityType = self::createRequestEntityType($metadata);
        $requestResourceSet = $metadata->addResourceSet('Requests', $requestEntityType);

        return $metadata;
    }

    private static function createRequestEntityType(SimpleMetadataProvider $metadata)
    {
        $et = $metadata->addEntityType(new \ReflectionClass('app\models\OData\Entities\Request'), 'Requests', self::MetaNamespace);
        $metadata->addKeyProperty($et, 'id', EdmPrimitiveType::INT64); 
        $metadata->addPrimitiveProperty($et, 'type_code', EdmPrimitiveType::STRING);
        $metadata->addPrimitiveProperty($et, 'status_code', EdmPrimitiveType::STRING);
        return $et;
    }

}

Try to open links:

• http:///odata.svc/$metadata

• http:///odata.svc/Requests?$format=json&$skip=1&$top=14&$inlinecount=allpages&$filter=status_code eq 'held'

• http:///odata.svc/Requests/$count?&$filter=status_code eq 'held'

• http:///odata.svc/Requests(2465)

For more details about URL format, see OData documentation.
