Next will be considered the most important changes.

Forced Resource Conversion

Through asset bundle you can convert resources automatically. For example, LESS in CSS. However, tracking all changes in the source files is quite expensive. Especially when importing one resource into another is done. In such cases, you can convert resources forcibly. To do this, the assetManager component assetManager configured as follows:

 [ 'components' => [ 'assetManager' => [ 'converter' => [ 'forceConvert' => true, ] ] ] ]; 

Selection of subqueries

The query builder supports subqueries in many places. Now in SELECT :

 $subQuery = (new Query)->select('COUNT(*)')->from('user'); $query = (new Query)->select(['id', 'count' => $subQuery])->from('post'); // $query represents the following SQL: // SELECT `id`, (SELECT COUNT(*) FROM `user`) AS `count` FROM `post` 

Preventing CSS reloading with AJAX requests

In Yii, there were already tools to prevent re-loading JavaScript with AJAX requests. Now there is also for CSS. To use this feature, YiiAsset registration is YiiAsset as shown below:

 yii\web\YiiAsset::register($view); 

Clearing the database schema cache

We have added a new command to clear the database schema cache. It will be useful for putting the code on the working servers. The command runs as follows:

 yii cache/flush-schema 

Helper Improvements

The Html::cssFile() method now supports the noscript option, intended to wrap the generated link tag into a noscript tag. This option can also be used when setting AssetBundle::cssOptions . For example:

 use yii\helpers\Html; echo Html::cssFile('/css/jquery.fileupload-noscript.css', ['noscript' => true]); 

Previously, StringHelper::truncate() supported trimming a simple string to a specified number of characters or words. HTML is now supported, which remains completely valid when trimming.

The class Inflector acquired a new method, sentence() , which gathers an array of words into a sentence. For example:

 use yii\helpers\Inflector; $words = ['Spain', 'France']; echo Inflector::sentence($words); // output: Spain and France $words = ['Spain', 'France', 'Italy']; echo Inflector::sentence($words); // output: Spain, France and Italy $words = ['Spain', 'France', 'Italy']; echo Inflector::sentence($words, ' & '); // output: Spain, France & Italy 

Bootstrap enhancements

CSS framework Bootstrap updated to version 3.3.x. If you want to use the old version, you can specify it explicitly in the project composer.json .

New properties have been added to the Bootstrap widgets, described in detail in the API documentation .

• yii\bootstrap\ButtonDropdown::$containerOptions .
• yii\bootstrap\Modal::$headerOptions .
• yii\bootstrap\Modal::$footerOptions .
• yii\bootstrap\Tabs::renderTabContent .
• yii\bootstrap\ButtonDropdown::$containerOptions .

MongoDB support improvements

The findAndModify operation findAndModify now supported by both yii\mongodb\Query and yii\mongodb\ActiveQuery . For example:

 User::find()->where(['status' => 'new'])->modify(['status' => 'processing']); 

MongoDB requests are now displayed on the debug pane. To use it, follow the debugger settings as follows:

 [ 'class' => 'yii\debug\Module', 'panels' => [ 'mongodb' => [ 'class' => 'yii\mongodb\debug\MongoDbPanel', ] ], ] 

Redis enhancements

The Redis extension now supports working through UNIX sockets, which is often 50% faster than working via TCP. The connection is configured as follows:

 [ 'class' => 'yii\redis\Connection', 'unixSocket' => '/var/run/redis/redis.sock', ]
