Yii2 RMDB Classes

Library with migrations and models to easily create RMDB tables and models.

Instalation

You can use composer to install the library tecnocen/yii2-rmdb by running the command;

composer require tecnocen/yii2-rmdb

or edit the composer.json file

require: {
    "tecnocen/yii2-rmdb": "*",
}

Usage

Create Migrations

There are 3 migration classes for each type of RMDB tables.

tecnocen\rmdb\migrations\CreatePivot

Uses the properties $createdByColumn, $createdAtColumn and methods createdByDefinition(), createdAtDefinition() to store the user and datetime a record was created.

class m170101_000001_product_sale extends \tecnocen\rmdb\migrations\CreatePivot
{
    public $createdByColumn = 'creation_user';
    public $createdAtColumn = 'creation_date';

    public function getTableName()
    {
        return 'product_sale';
    }

    public function columns()
    {
        return [
            'product_id' => ...,
            'sale_id' => ...,
        ];
    }

    public function compositePrimaryKeys()
    {
        return ['product_id', 'sale_id'];
    }
}

tecnocen\rmdb\migrations\CreateEntity

Extends the previous class adding the properties $updatedByColumn, $updatedAtColumn and methods updatedByDefinition(), updatedAtDefinition() to store the user and datetime a record was updated.

class m170101_000001_product extends \tecnocen\rmdb\migrations\CreateEntity
{
    public $createdByColumn = 'creation_user';
    public $createdAtColumn = 'creation_date';
    public $updatedByColumn = 'edition_user';
    public $updatedAtColumn = 'edition_date';

    public function getTableName()
    {
        return 'product';
    }

    public function columns()
    {
        return [
            'id' => $this->prymariKey()->...,
            'name' => ...,
        ];
    }
}

tecnocen\rmdb\migrations\CreatePersistentEntity

A persistent entity remains stored in the database after the user deletes it.

The library yii2tech/ar-softdelete provides support for this functionality.

CreateEntity extends the previous class adding the properties $deletedByColumn, $deletedAtColumn and methods deletedByDefinition(), deletedAtDefinition() to store the user and datetime a record was deleted.

class m170101_000001_sale extends \tecnocen\rmdb\migrations\CreateEntity
{
    public $createdByColumn = 'creation_user';
    public $createdAtColumn = 'creation_date';
    public $updatedByColumn = 'edition_user';
    public $updatedAtColumn = 'edition_date';
    public $deletedByColumn = 'deletion_user';
    public $deletedAtColumn = 'deletion_date';

    public function getTableName()
    {
        return 'product';
    }

    public function columns()
    {
        return [
            'id' => $this->prymariKey()->...,
            'store_id' => ...,
        ];
    }
}

RMDB Module

This library uses a custom module to help configure all the extended models in an unified way.

configure it in your common\config\main.php in yii-app-advanced and common\config.php in yii-app-basic.

use tecnocen\rmdb\Module as RmdbModule;

return [
    // ...
    'modules' => [
        'rmdb' => [
            'class' => RmdbModule::class,
            'timestampClass' => ..., // optional
            'blameableClass' => ..., // optional
            'softDeleteClass' => ..., // optional
            'timestampValue' => time(), // optional by default uses `now()`
            'defaultUserId' => 5, // optional
        ],
    ],
];

Models

Like the migrations there are 3 classes for models.

tecnocen\rmdb\models\Pivot

Adds protected properties $createdByAttribute and $createdAtAttribute to configure the names of the attributes. The class will automatically load the needed behaviors and configure them to use the attributes as provided by this properties.

class ProductSale extends \tecnocen\rmdb\models\Pivot
{
    protected $createdByAttribute = 'creation_user';
    protected $createdAtAttribute = 'creation_date';

    // rest of model methods and logic
}

tecnocen\rmdb\models\Entity

Extends the previos class and adds protected properties $updatedByAttribute and $updatedAtAttribute to configure the names of the attributes. The class will automatically load the needed behaviors and configure them to use the attributes as provided by this properties.

class Product extends \tecnocen\rmdb\models\Entity
{
    protected $createdByAttribute = 'creation_user';
    protected $createdAtAttribute = 'creation_date';
    protected $updatedByAttribute = 'edition_user';
    protected $updatedAtAttribute = 'edition_date';

    // rest of model methods and logic
}

tecnocen\rmdb\models\PersistentEntity

Extends the previos class and adds protected properties $deletedByAttribute and $deletedAtAttribute to configure the names of the attributes. The class will automatically load the needed behaviors and configure them to use the attributes as provided by this properties.

class Product extends \tecnocen\rmdb\models\PersistentEntity
{
    protected $createdByAttribute = 'creation_user';
    protected $createdAtAttribute = 'creation_date';
    protected $updatedByAttribute = 'edition_user';
    protected $updatedAtAttribute = 'edition_date';
    protected $deletedAtAttribute = 'deletion_user';
    protected $deletedAtAttribute = 'deletion_date';

    // rest of model methods and logic
}
