Yii 2 Models add functionality for load with relation (loadAll($POST)), & transactional save with relation (saveAll())

Installation

The preferred way to install this extension is through composer.

Either run

$ composer require 'mootensai/yii2-relation-trait:dev-master'

or add

"mootensai/yii2-relation-trait": "*"

to the require section of your composer.json file.

Usage At Model

class MyModel extends ActiveRecord{
    use \mootensai\relation\RelationTrait;
}

Array Input & Usage At Controller

It takes a normal array of POST. This is the example

// sample at controller
//$_POST['ParentClass'] = ['attr1' => 'value1','attr2' => 'value2'];
//$_POST['RelatedClass'][0] = ['attr1' => 'value1','attr2' => 'value2'];      
if($model->loadAll(Yii:$app->request->post()) && $model->saveAll()){
    return $this->redirect(['view', 'id' => $model->id, 'created' => $model->created]);
}

#Features

Array Output

// I use this to send model & related through JSON / Serialize
print_r($model->getAttributesWithRelatedAsPost());

Array
(
    [MainClass] => Array
        (
            [attr1] => value1
            [attr2] => value2
        )

    [RelatedClass] => Array
        (
            [0] => Array
                (
                    [attr1] => value1
                    [attr2] => value2
                )
        )

)

print_r($model->getAttributesWithRelated());

Array
(
    [attr1] => value1
    [attr2] => value2
    [relationName] => Array
        (
            [0] => Array
                (
                    [attr1] => value1
                    [attr2] => value2
                )
        )
)

Use Transaction

So your data will be atomic (see : http://en.wikipedia.org/wiki/ACID)

Use Normal Save

So your behaviors still works

Add Validation At Main Model

$form->errorSummary($model);

will give you

<<Related Class Name>> #<<index + 1>> : <<error message>>
My Related Model #1 : Attribute is required

It Works On Auto Incremental PK Or Not (I Have Tried Use UUID)

See here if you want to use my behavior : https://github.com/mootensai/yii2-uuid-behavior

#To Do Test it on another DB. I only test it on MySQL.

I'm open for any improvement
