The following upgrading instructions are cumulative. That is, if you want to upgrade from version A to version C and there is version B between A and C, you need to following the instructions for both A and B.
If you are using Composer to upgrade Yii, you should run the following command first (once for all) to install the composer-asset-plugin, before you update your project:
php composer.phar global require "fxp/composer-asset-plugin:~1.0.0"
You also need to add the following code to your project's composer.json file:
"extra": {
"asset-installer-paths": {
"npm-asset-library": "vendor/npm",
"bower-asset-library": "vendor/bower"
}
}
It is also a good idea to upgrade composer itself to the latest version if you see any problems:
php composer.phar self-update
If you used clearAll() or clearAllAssignments() of yii\rbac\DbManager, you should replace them withremoveAll() and removeAllAssignments() respectively.
If you created RBAC rule classes, you should modify their execute() method by adding $user as the first parameter: execute($user, $item, $params). The $user parameter represents the ID of the user currently being access checked. Previously, this is passed via $params['user'].
If you override yii\grid\DataColumn::getDataCellValue() with visibility protected you have to change visibility topublic as visibility of the base method has changed.
If you have classes implementing yii\web\IdentityInterface (very common), you should modify the signature offindIdentityByAccessToken() as public static function findIdentityByAccessToken($token, $type = null). The new $type parameter will contain the type information about the access token. For example, if you useyii\filters\auth\HttpBearerAuth authentication method, the value of this parameter will beyii\filters\auth\HttpBearerAuth. This allows you to differentiate access tokens taken by different authentication methods.
If you are sharing the same cache across different applications, you should configure the keyPrefix property of the cache component to use some unique string. Previously, this property was automatically assigned with a unique string.
If you are using dropDownList(), listBox(), activeDropDownList(), or activeListBox() of yii\helpers\Html, and your list options use multiple blank spaces to format and align option label texts, you need to specify the optionencodeSpaces to be true.
If you are using yii\grid\GridView and have configured a data column to use a PHP callable to return cell values (via yii\grid\DataColumn::value), you may need to adjust the signature of the callable to be function ($model, $key, $index, $widget). The $key parameter was newly added in this release.
yii\console\controllers\AssetController is now using hashes instead of timestamps. Replace all {ts} with{hash}.
The database table of the yii\log\DbTarget now needs a prefix column to store context information. You can add it with ALTER TABLE log ADD COLUMN prefix TEXT AFTER log_time;.
The
fileinfo PHP extension is now required by Yii. If you use
yii\helpers\FileHelper::getMimeType(), make sure you have enabled this extension. This extension is
builtin in php above
5.3.
Please update your main layout file by adding this line in the <head> section: <?= Html::csrfMetaTags() ?>. This change is needed because yii\web\View no longer automatically generates CSRF meta tags due to issue #3358.
If your model code is using the file validation rule, you should rename its types option to extensions.
MailEvent class has been moved to the yii\mail namespace. You have to adjust all references that may exist in your code.
The behavior and signature of ActiveRecord::afterSave() has changed. ActiveRecord::$isNewRecord will now always be false in afterSave and also dirty attributes are not available. This change has been made to have a more consistent and expected behavior. The changed attributes are now available in the new parameter of afterSave()$changedAttributes. $changedAttributes contains the old values of attributes that had changed and were saved.
ActiveRecord::updateAttributes() has been changed to not trigger events and not respect optimistic locking anymore to differentiate it more from calling update(false) and to ensure it can be used in afterSave() without triggering infinite loops.
If you are developing RESTful APIs and using an authentication method such as yii\filters\auth\HttpBasicAuth, you should explicitly configure yii\web\User::enableSession in the application configuration to be false to avoid starting a session when authentication is performed. Previously this was done automatically by authentication method.
mail component was renamed to mailer, yii\log\EmailTarget::$mail was renamed toyii\log\EmailTarget::$mailer. Please update all references in the code and config files.
yii\caching\GroupDependency was renamed to TagDependency. You should create such a dependency using the code new \yii\caching\TagDependency(['tags' => 'TagName']), where TagName is similar to the group name that you previously used.
If you are using the constant YII_PATH in your code, you should rename it to YII2_PATH now.
You must explicitly configure yii\web\Request::cookieValidationKey with a secret key. Previously this is done automatically. To do so, modify your application configuration like the following:
return [
// ...
'components' => [
'request' => [
'cookieValidationKey' => 'your secret key here',
],
],
];
Note: If you are using the Advanced Project Template you should not add this configuration to common/configor console/config because the console application doesn't have to deal with CSRF and uses its own request that doesn't have cookieValidationKey property.
yii\rbac\PhpManager now stores data in three separate files instead of one. In order to convert old file to new ones save the following code as convert.php that should be placed in the same directory your rbac.php is in:
<?php
$oldFile = 'rbac.php';
$itemsFile = 'items.php';
$assignmentsFile = 'assignments.php';
$rulesFile = 'rules.php';
$oldData = include $oldFile;
function saveToFile($data, $fileName) {
$out = var_export($data, true);
$out = "<?php\nreturn " . $out . ";";
$out = str_replace(['array (', ')'], ['[', ']'], $out);
file_put_contents($fileName, $out);
}
$items = [];
$assignments = [];
if (isset($oldData['items'])) {
foreach ($oldData['items'] as $name => $data) {
if (isset($data['assignments'])) {
foreach ($data['assignments'] as $userId => $assignmentData) {
$assignments[$userId][] = $assignmentData['roleName'];
}
unset($data['assignments']);
}
$items[$name] = $data;
}
}
$rules = [];
if (isset($oldData['rules'])) {
$rules = $oldData['rules'];
}
saveToFile($items, $itemsFile);
saveToFile($assignments, $assignmentsFile);
saveToFile($rules, $rulesFile);
echo "Done!\n";
Run it once, delete rbac.php. If you've configured authFile property, remove the line from config and instead configure itemFile, assignmentFile and ruleFile.
Static helper yii\helpers\Security has been converted into an application component. You should change all usage of its methods to a new syntax, for example: instead of yii\helpers\Security::hashData() use Yii::$app->getSecurity()->hashData(). The generateRandomKey() method now produces not an ASCII compatible output. UsegenerateRandomString() instead. Default encryption and hash parameters has been upgraded. If you need to decrypt/validate data that was encrypted/hashed before, use the following configuration of the 'security' component:
return [
'components' => [
'security' => [
'derivationIterations' => 1000,
],
// ...
],
// ...
];
If you are using query caching, you should modify your relevant code as follows, as beginCache() and endCache()are replaced by cache():
$db->cache(function ($db) {
// ... SQL queries that need to use query caching
}, $duration, $dependency);
Due to significant changes to security you need to upgrade your code to use
\yii\base\Security component instead of helper. If you have any data encrypted it should be re-encrypted. In order to do so you can use old security helper
as explained by @docsolver at github.
[[yii\helpers\Url::to()]] will no longer prefix base URL to relative URLs. For example, Url::to('images/logo.png') will return images/logo.png directly. If you want a relative URL to be prefix with base URL, you should make use of the alias @web. For example, Url::to('@web/images/logo.png') will return /BaseUrl/images/logo.png.
The following properties are now taking false instead of null for "don't use" case:
yii\bootstrap\NavBar::$brandLabel.yii\bootstrap\NavBar::$brandUrl.yii\bootstrap\Modal::$closeButton.yii\bootstrap\Modal::$toggleButton.yii\bootstrap\Alert::$closeButton.yii\widgets\LinkPager::$nextPageLabel.yii\widgets\LinkPager::$prevPageLabel.yii\widgets\LinkPager::$firstPageLabel.yii\widgets\LinkPager::$lastPageLabel.
The format of the Faker fixture template is changed. For an example, please refer to the fileapps/advanced/common/tests/templates/fixtures/user.php.
The signature of all file downloading methods in yii\web\Response is changed, as summarized below:
sendFile($filePath, $attachmentName = null, $options = [])sendContentAsFile($content, $attachmentName, $options = [])sendStreamAsFile($handle, $attachmentName, $options = [])xSendFile($filePath, $attachmentName = null, $options = [])
The signature of callbacks used in yii\base\ArrayableTrait::fields() is changed from function ($field, $model) { to function ($model, $field) {.
Html::radio(), Html::checkbox(), Html::radioList(), Html::checkboxList() no longer generate the container tag around each radio/checkbox when you specify labels for them. You should manually render such container tags, or set the item option for Html::radioList(), Html::checkboxList() to generate the container tags.
The formatter class has been refactored to have only one class regardless whether PHP intl extension is installed or not. Functionality of yii\base\Formatter has been merged into yii\i18n\Formatter and yii\base\Formatter has been removed so you have to replace all usage of yii\base\Formatter with yii\i18n\Formatter in your code. Also the API of the Formatter class has changed in many ways. The signature of the following Methods has changed:
asDateasTimeasDatetimeasSize has been split up into asSize and asShortSizeasCurrencyasDecimalasPercentasScientific
The following methods have been removed, this also means that the corresponding format which may be used by a GridView or DetailView is not available anymore:
Also due to these changes some formatting defaults have changes so you have to check all your GridView and DetailView configuration and make sure the formatting is displayed correctly.
The configuration for asSize() has changed. It now uses the configuration for the number formatting from intl and only the base is configured using $sizeFormatBase.
The specification of the date and time formats is now using the ICU pattern format even if PHP intl extension is not installed. You can prefix a date format with php: to use the old format of the PHP date()-function.
The DateValidator has been refactored to use the same format as the Formatter class now (see previous change). When you use the DateValidator and did not specify a format it will now be what is configured in the formatter class instead of 'Y-m-d'. To get the old behavior of the DateValidator you have to set the format explicitly in your validation rule:
['attributeName', 'date', 'format' => 'php:Y-m-d'],
beforeValidate(), beforeValidateAll(), afterValidate(), afterValidateAll(), ajaxBeforeSend() andajaxComplete() are removed from ActiveForm. The same functionality is now achieved via JavaScript event mechanism like the following:
$('#myform').on('beforeValidate', function (event, messages, deferreds) {
// called when the validation is triggered by submitting the form
// return false if you want to cancel the validation for the whole form
}).on('beforeValidateAttribute', function (event, attribute, messages, deferreds) {
// before validating an attribute
// return false if you want to cancel the validation for the attribute
}).on('afterValidateAttribute', function (event, attribute, messages) {
// ...
}).on('afterValidate', function (event, messages) {
// ...
}).on('beforeSubmit', function () {
// after all validations have passed
// you can do ajax form submission here
// return false if you want to stop form submission
});
The signature of View::registerJsFile() and View::registerCssFile() has changed. The $depends and$position paramaters have been merged into $options. The new signatures are as follows:
registerJsFile($url, $options = [], $key = null)registerCssFile($url, $options = [], $key = null)
