Improved PostgreSQL schemas for Yii2.

Yii 2.0.14 and above supports array and json DB types.

Supports follow types for ActiveRecord models:

• array, Yii 2.0.14 and above supports array DB type
• json, Yii 2.0.14 and above supports json DB type
• composite, https://www.postgresql.org/docs/current/static/rowtypes.html
• domain, https://www.postgresql.org/docs/current/static/sql-createdomain.html
• fixes type bit, issue #7682
• converts Postgres types timestamp, date and time to PHP type \DateTime and vice versa.

Limitation

Since version 1.2.0 requires Yii 2.0.14 and above.
You can use version 1.1.11 if you have Yii 2.0.13 and below.

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist tigrov/yii2-pgsql

or add

"tigrov/yii2-pgsql": "~1.0"

to the require section of your composer.json file.

Configuration

Once the extension is installed, add following code to your application configuration:

return [
    //...
    'components' => [
        'db' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'pgsql:host=localhost;dbname=<database>',
            'username' => 'postgres',
            'password' => '<password>',
            'schemaMap' => [
                'pgsql'=> 'tigrov\pgsql\Schema',
            ],
        ],
    ],
];

Specify the desired types for a table

CREATE TABLE public.model (
    id serial NOT NULL,
    attribute1 text[],
    attribute2 jsonb,
    attribute3 timestamp DEFAULT now(),
    CONSTRAINT model_pkey PRIMARY KEY (id)
);

Configure Model's rules

/**
 * @property string[] $attribute1 array of string
 * @property array $attribute2 associative array or just array
 * @property integer|string|\DateTime $attribute3 for more information about the type see \Yii::$app->formatter->asDatetime()
 */
class Model extends ActiveRecord
{
    //...
    public function rules()
    {
        return [
            [['attribute1'], 'each', 'rule' => ['string']],
            [['attribute2', 'attribute3'], 'safe'],
        ];
    }
}

Usage

You can then save array, json and timestamp types in database as follows:

/**
 * @var ActiveRecord $model
 */
$model->attribute1 = ['some', 'values', 'of', 'array'];
$model->attribute2 = ['some' => 'values', 'of' => 'array'];
$model->attribute3 = new \DateTime('now');
$model->save();

and then use them in your code

/**
 * @var ActiveRecord $model
 */
$model = Model::findOne($pk);
$model->attribute1; // is array
$model->attribute2; // is associative array (decoded json)
$model->attribute3; // is \DateTime

Composite types
