Yii 2的ArangoDB扩展

此扩展为Yii2框架提供了ArangoDB的集成。

安装

此扩展需要ArangoDB PHP扩展

安装此扩展的首选方式是通过composer

运行以下命令之一:

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

或者

"explosivebit/yii2-arangodb": "*"

将以下内容添加到您的composer.json文件的require部分。

通用用法

要使用此扩展,只需在您的应用程序配置中添加以下代码

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 => '',
            ],
        ],
    ],
];

使用连接实例,您可以访问数据库、集合和文档。

要执行"查找"查询,应使用[[\explosivebit\arangodb\Query]]

use explosivebit\arangodb\Query;

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

使用ArangoDB ActiveRecord

此扩展提供了与[[\yii\db\ActiveRecord]]相似的ActiveRecord解决方案。要声明ActiveRecord类,您需要扩展[[\explosivebit\arangodb\ActiveRecord]]并实现collectionName和'attributes'方法

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'];
    }
}

注意:集合主键名称('_key')应始终明确设置为属性。

您可以使用[[\yii\data\ActiveDataProvider]]与[[\explosivebit\arangodb\Query]]和[[\explosivebit\arangodb\ActiveQuery]]一起使用

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

$query = new Query;
$query->from('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();

使用迁移

ArangoDB迁移通过[[explosivebit\arangodb\console\controllers\MigrateController]]管理,它是常规[[\yii\console\controllers\MigrateController]]的类似物。

为了启用此命令,您应调整控制台应用程序的配置

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

以下是此命令的一些常见用法

# 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

创建迁移后,您可以配置迁移

在以下示例中启动迁移时,您将创建一个名为迁移名称的正常文档集合,您需要添加一个额外的参数Type => 3以创建边集合。此类查询的示例:$this-> createCollection ('services', ['Type' => 3] );如果您想创建文档集合,则删除'Type' => 3或将其数字3替换为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');
    }
}

使用调试面板

将ArangoDb面板添加到您的yii\debug\Module配置中

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