ArangoDb Extension for Yii 2

This extension provides the ArangoDB integration for the Yii2 framework.

Installation

This extension requires ArangoDB PHP Extension

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist explosivebit/yii2-arangodb "*"

or add

"explosivebit/yii2-arangodb": "*"

to the require section of your composer.json.

General Usage

To use this extension, simply add the following code in your application configuration:

return [
    //....
    'components' => [
        'arangodb' => [
            'class' => '\explosivebit\arangodb\Connection',
            'connectionOptions' => [
                ArangoDBClient\ConnectionOptions::OPTION_DATABASE => "mydatabase",
                ArangoDBClient\ConnectionOptions::OPTION_ENDPOINT => 'tcp://127.0.0.1:8529',
                ArangoDBClient\ConnectionOptions::OPTION_AUTH_TYPE => 'Basic',
                //ArangoDBClient\ConnectionOptions::OPTION_AUTH_USER   => '',
                //ArangoDBClient\ConnectionOptions::OPTION_AUTH_PASSWD => '',
            ],
        ],
    ],
];

Using the connection instance you may access databases, collections and documents.

To perform "find" queries, you should use [[\explosivebit\arangodb\Query]]:

use explosivebit\arangodb\Query;

$query = new Query;
// compose the query
$query->select(['name', 'status'])
    ->collection('customer')
    ->limit(10);
// execute the query
$rows = $query->all();

Using the ArangoDB ActiveRecord

This extension provides ActiveRecord solution similar ot the [[\yii\db\ActiveRecord]]. To declare an ActiveRecord class you need to extend [[\explosivebit\arangodb\ActiveRecord]] and implement the collectionName and 'attributes' methods:

use explosivebit\arangodb\ActiveRecord;

class Customer extends ActiveRecord
{
    /**
     * @return string the name of the index associated with this ActiveRecord class.
     */
    public static function collectionName()
    {
        return 'customer';
    }

    /**
     * @return array list of attribute names.
     */
    public function attributes()
    {
        return ['_key', 'name', 'email', 'address', 'status'];
    }
}

Note: collection primary key name ('_key') should be always explicitly setup as an attribute.

You can use [[\yii\data\ActiveDataProvider]] with [[\explosivebit\arangodb\Query]] and [[\explosivebit\arangodb\ActiveQuery]]:

use yii\data\ActiveDataProvider;
use explosivebit\arangodb\Query;

$query = new Query;
$query->collection('customer')->where(['status' => 2]);
$provider = new ActiveDataProvider([
    'query' => $query,
    'pagination' => [
        'pageSize' => 10,
    ]
]);
$models = $provider->getModels();
use yii\data\ActiveDataProvider;
use app\models\Customer;

$provider = new ActiveDataProvider([
    'query' => Customer::find(),
    'pagination' => [
        'pageSize' => 10,
    ]
]);
$models = $provider->getModels();

Using Migrations

ArangoDB migrations are managed via [[explosivebit\arangodb\console\controllers\MigrateController]], which is an analog of regular [[\yii\console\controllers\MigrateController]].

In order to enable this command you should adjust the configuration of your console application:

return [
    // ...
    'controllerMap' => [
        'arangodb-migrate' => 'explosivebit\arangodb\console\controllers\MigrateController'
    ],
];

Below are some common usages of this command:

# creates a new migration named 'create_user_collection'
yii arangodb-migrate/create create_user_collection

# applies ALL new migrations
yii arangodb-migrate

# Apply 1 migration
yii arangodb-migrate/up 1

# reverts the last applied migration
yii arangodb-migrate/down

# Rollback 1 migration
yii arangodb-migrate/down 1

Once migration created, you can configure the migration:

When you start the migration as in the example below, you create a normal document collection with the migration name, you need to add an additional parameter Type => 3 to create the edge collection. Example of such a query: $this-> createCollection ('services', ['Type' => 3] ); If you want to create a document collection, then delete the 'Type' => 3 or replace the number 3 with 2.

class m170413_210957_create_services_collection extends \explosivebit\arangodb\Migration
{
    public function up()
    {
        # When you start the migration, a collection of "services" with the edge type is created
        $this->createCollection('services',['Type' => 3]);
    }

    public function down()
    {
        # When the migration rollback starts, the collection "services"
        $this->dropCollection('services');
    }
}

Using Debug Panel

Add ArangoDb panel to your yii\debug\Module configuration

return [
    'bootstrap' => ['debug'],
    'modules' => [
        'debug' => 'yii\debug\Module',
        'panels' => [
            'arango' => [
                'class' => 'explosivebit\arangodb\panels\arangodb\ArangoDbPanel',
            ],
        ],
        ...
    ],
    ...
];
