Active Record MultiTenant Extension

This extension provides support for ActiveRecord MultiTenant.

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist solutosoft/yii-multitenant

or add

"solutosoft/yii-multitenant": "*"

Usage

1. Creates table with tenant_id column:

class m191023_101232_create_post extends Migration
{
    /**
     * {@inheritdoc}
     */
    public function up()
    {
        $this->createTable('post', [
            'id' =>  $this->primaryKey(),
            'title' => $this->string()->notNull(),
            'category_id' => $this->integer(),
            'content' => $this->string()            
            'tenant_id' => $this->integer(),
        ]);
        
        $this->createTable('category', [
            'id' =>  $this->primaryKey(),
            'name' => $this->string()->notNull(),            
            'tenant_id' => $this->integer(),
        ]);
    }
}

2. Adds TenantInterface to user model:

use solutosoft\multitenant\MultiTenantRecord;

class User extends MultiTenantRecord implements IdentityInterface, TenantInterface    
{
    /**
     * {@inheritdoc}
     */
    public function getTenantId()
    {
        return // logic to determine tenant from current user
    }
    
    /**
     * Finds user by username attribute
     * This is an example where tenant filter is disabled
     */
    public static function findByUsername($username)
    {
        return static::find()->withoutTenant()->where(['username' => $username]);
    }
    
    ...
    
}

3. Extends models with tenant_id attribute from MultiTenantRecord intead of ActiveRecord:

use solutosoft\multitenant\MultiTenantRecord;

class Post extends MultiTenantRecord
{    
    ...   
}

class Category extends MultiTenantRecord
{    
    ...   
}

Now when you save or execute some query the tenant_id column will be used. Example:

// It's necessary the user will be logged in

$posts = \app\models\Post::find()->where(['category_id' => 1])->all();
// SELECT * FROM `post` WHERE `category_id` = 1 and `tenant_id` = 1;

$category = \app\models\Category([
  'name' => 'framework'
]);
$category->save();
// INSERT INTO `category` (`name`, `tenant_id`) values ('framework', 1);
