Below we summarize some of most important features/fixes included in this release. A complete list of changes can be found in the CHANGELOG.

Action filter ¶

\yii\base\ActionFilter now supports wildcards for only and except options which is useful when it's attached to the module or application:

return [
    'as filter' => [
        'class' => 'app\filters\SomeFilter',
        'only' => [
            'particular/*', // all actions in controller 'particular'
            '*/captcha', // all 'captcha' actions in all controllers
        ],
    ],
    // ...
];

Performance improvements ¶

• Message translation performance was increased for database backend by examining queries and adding proper indexes.
• Oracle database schema was improved to be read faster.

Schema builder and migrations ¶

Schema builder which is used in migrations got some enhancements.

First of all, there's a new method null() to specify nullability explicitly. Also the column nullability is now set automatically in case default value is null.

$type = $this->string(42)->null();

Moreover, a new method was added to append custom SQL to the end of query generated:

$type = $this->string(15)->notNull()->append('collate ascii_bin')->append('character set ascii');

Migrations syntax for automatic generation of code was adjusted a bit. _table and _column suffixes are now required:

./yii migrate/create create_user_table
./yii migrate/create add_name_column_to_user_table

Data providers and widgets ¶

This release enhancements for grids and providers are all about labels. \yii\data\ArrayDataProvider got a $modelClass property that specifies a model which is used to provide column labels when data array is empty. Additionally \yii\grid\DataColumn, which defines base behavior for all data columns, is now trying to extract attribute label from the filterModel of the grid in case it cannot get it otherwise.

Refactorings ¶

A sub-interface called CheckAccessInterface was extracted from RBAC ManagerInterface which could be useful for custom access checking implementations.

\yii\web\User::loginByCookie() was refactored in order to make it easier to override.

Assets ¶

When listing files in an asset bundle you can set paths to null to tell asset manager not to register them at all. It is useful for registering extra scripts for development environment:

<?php
namespace common\assets;
use yii\web\AssetBundle;

class ReactAsset extends AssetBundle
{
    public $sourcePath = null;

    public $js = [
        YII_ENV_DEV ? "//fb.me/react-15.0.1.js" : "//fb.me/react-15.0.1.min.js",
        YII_ENV_DEV ? "//fb.me/react-dom-15.0.1.js" : "//fb.me/react-dom-15.0.1.min.js",
        YII_ENV_DEV ? "//cdnjs.cloudflare.com/ajax/libs/babel-core/5.6.15/browser.js" : null,
    ];
}

Logging ¶

\yii\log\Target::$logVars now supports fine-grained configurations of what's to be logged:

• _SESSION - log global session variable. That's the same as before.
• _SESSION.id - log only id from session.
• !_SESSION.secret - don't log secret from session.

The logic for such filtering was extracted to \yii\helpers\ArrayHelper::filter() so you can use it if needed.

Markdown ¶

You can now configure default flavor for yii\helpers\Markdown calls via $defaultFlavor.
