Activerecord Behaviors for Yii2
===============================
Installation
------------
The preferred way to install this extension is through [composer](http://getcomposer.org/download/).
Either run
```
php composer.phar require mdmsoft/yii2-ar-behaviors "~1.0"
```
or add
```
"mdmsoft/yii2-ar-behaviors": "~1.0"
```
to the require section of your `composer.json` file.
Query Scope
----------
`QueryScopeBehavior` will automatically attached to `ActiveQuery` via `Yii::$container`. You can use this behavior to
create query scope from `ActiveRecord`.
```php
class Sales extends ActiveRecord
{
...
public static function defaultScope($query)
{
$query->andWhere(['status' => self::STATUS_OPEN]);
}
public static function bigOrder($query, $ammount=100)
{
$query->andWhere(['>','ammount',$ammount]);
}
}
----
// get all opened sales
Sales::find()->all(); // apply defaultScope
// opened sales and order bigger than 200
Sales::find()->bigOrder(200)->all();
```
ExtendedBehavior
----------------
Extend `Activerecord` with out inheriting :grinning: .
This behavior use to merge two table and treated as one ActiveRecord.
Example:
We have model `CustomerDetail`
```php
/**
* @property integer $id
* @property string $full_name
* @property string $organisation
* @property string $address1
* @property string $address2
*/
class CustomerDetail extends ActiveRecord
{
}
```
and model `Customer`
```php
/**
* @property integer $id
* @property string $name
* @property string $email
*/
class Customer extends ActiveRecord
{
public function behaviors()
{
return [
[
'class' => 'mdm\behaviors\ar\ExtendedBehavior',
'relationClass' => CustomerDetail::className(),
'relationKey' => ['id' => 'id'],
],
];
}
}
```
After that, we can access `CustomerDetail` property from `Customer` as their own property
```php
$model = new Customer();
$model-name = 'Doflamingo';
$model->organisation = 'Donquixote Family';
$model->address = 'North Blue';
$model->save(); // it will save this model and related model
```
RelationBehavior
----------------
Use to save model and its relation.
```php
class Order extends ActiveRecord
{
public function getItems()
{
return $this->hasMany(Item::className(),['order_id'=>'id']);
}
public function behaviors()
{
return [
[
'class' => 'mdm\behaviors\ar\RelationBehavior',
'beforeRSave' => function($item){
return $item->qty != 0;
}
],
];
}
}
```
usage
```php
$model = new Order();
if($model->load(Yii::$app->request->post()){
$model->items = Yii::$app->request->post('Item',[]);
$model->save();
}
```
RelationTrait
-------------
Similar with RelationBehavior
```php
class Order extends ActiveRecord
{
use \mdm\behavior\ar\RelationTrait;
public function getItems()
{
return $this->hasMany(Item::className(),['order_id'=>'id']);
}
public function setItems($value)
{
$this->loadRelated('items', $value);
}
public function beforeRSave($item)
{
return $item->qty != 0;
}
}
```
usage
```php
$model = new Order();
if($model->load(Yii::$app->request->post()){
$model->items = Yii::$app->request->post('Item',[]);
$model->save();
}
```
