Installation ¶

The preferred way to install this extension is through composer.

php composer.phar require --prefer-dist mdmsoft/yii2-autonumber "dev-master"

or add

"mdmsoft/yii2-autonumber": "*"

to the require section of your composer.json file.

Usage ¶

Prepare required table by execute yii migrate.

yii migrate --migrationPath=@mdm/autonumber/migrations

if wantn't use db migration. you can create required table manually.

CREATE TABLE auto_number (
    "group" varchar(32) NOT NULL,
    "number" int,
    optimistic_lock int,
    update_time int,
    PRIMARY KEY ("group")
);

Once the extension is installed, simply modify your ActiveRecord class:

public function behaviors()
{
    return [
        [
            'class' => 'mdm\autonumber\Behavior',
            'attribute' => 'sales_num', // required
            'group' => $this->id_branch, // optional
            'value' => 'SA.'.date('Y-m-d').'.?' , // format auto number. '?' will be replaced with generated number
            'digit' => 4 // optional, default to null. 
        ],
        ...
    ];
}

// it will set value $model->sales_num as 'SA.2014-06-25.0001'

Instead of behavior, you can use this extension as validator

public function rules()
{
    return [
        [['sales_num'],'mdm\autonumber\NextValueValidator','format'=>'SA.'.date('Y-m-d').'.?'],
        ...
    ];
}
