Yii2 User storage

Simple storage of user settings, options & etc., _(*1)

Installation

The preferred way to install this extension is through composer., _(*2)

Either run, _(*3)

php composer.phar require --prefer-dist hunter-kaan/yii2-user-storage "^1.0"

or add, _(*4)

"hunter-kaan/yii2-user-storage": "^1.0"

to the require section of your composer.json file., _(*5)

Configuration

To use this extension, you have to configure the Storage class in your application configuration:, _(*6)

return [
    //....
    'components' => [
        'userStorage' => [
            'class' => HunterKaan\UserStorage\Storage::class,
            'keyPrefix' => '',
            'userStorageTable' => '{{%user_storage}}',
            'userTable' => '{{%user}}',
        ],
    ]
    //....
];

Before you can go on you need to create those tables in the database. To do this, you can use the migration stored in @vendor/hunter-kaan/yii2-user-storage/migrations:, _(*7)

php yii migrate/up --migrationPath=@vendor/hunter-kaan/yii2-user-storage/migrations

The component extends the yii\caching\Cache class., _(*8)

A typical usage is like the following:, _(*9)

    // To get default form values.
    $formDefaultValues = Yii::$app->userStorage->get('myForm-default-values');

    // To store user choose as default form values.
    $formDefaultValues = ['city_id' => 3];
    Yii::$app->userStorage->set('myForm-options', $formDefaultValues);

Examples

Model service

Store and load model data:, _(*10)

In your controller:, _(*11)

    $model = new Post();
    $model->loadDefaultValues();

    // Create model service
    $storageService = Yii::$app->userStorage->buildModelService($model);

    // Load data from user storage to model
    $storageService->load();

    // ...
    if ($model->load(Yii::$app->getRequest()->getBodyParam()) && $model->save()) {
        // Save user data to storage
        $storageService->save();
        // ...
    }

The model must implement interface HunterKaan\UserStorage\UserStorageModelInterface:, _(*12)

class Post extends ActiveRecord implements UserStorageModelInterface
{
    // ...

    /**
     * Storage safe attributes.
     *
     * @return array
     */
    public function userStorageAttributes()
    {
        return ['pinned'];
    }
    // ...

or you must specify safe attributes when loading(saving):, _(*13)

    // Create model service
    $storageService = Yii::$app->userStorage->buildModelService($model);

    // Load data from user storage to model
    $storageService->load(null, ['pinned']);
    // ...
    if ($model->load(Yii::$app->getRequest()->getBodyParam()) && $model->save()) {
        // Save user data to storage
        $storageService->save(null, ['pinned']);
        // ...
    }

By default model storage key is YourModel::class, but it can be redefined:, _(*14)

    // Create model service
    $storageService = Yii::$app->userStorage->buildModelService($model);

    // Load data from user storage to model
    $storageService->load(CommonModel::class);
    // ...
    if ($model->load(Yii::$app->getRequest()->getBodyParam()) && $model->save()) {
        // Save user data to storage
        $storageService->save(CommonModel::class);
        // ...
    }

Note

Only secure attributes can be saved. See models guide.
If the model does not implement the UserStorageModelInterface interface and when loading(saving) does not specify attributes, all safe attributes will be saved.
At the moment, only storage in the database is supported.
