How to Russify validation messages, etc. in Yii2?

Question

Yii

Created an application in Yii2. Read the documentation about localization. However, to understand the process, you need to see the localization with an example.
Does anyone have an example of localizing an application into Russian.
It is required to translate, for example, validation error messages.

Answer 1

Specify the Russian language in the application config.

Answer 2

If the labels - then the models have an attributeLabels field - you write names there using Yii::t
Validation messages - then each validator has a message field (configured in the rules of the model for each validator separately), where you also write a message using Yii:: t. Some validators have many fields for different cases (for example, for StringValidator - tooShort, tooLong, notEqual) - they must also be specified when configuring the validator (if you use these validation features, for example, checking for the minimum string length).
Well, of course, in the application config, register the Russian language

Answer 3

OK. This is clear.
How to translate the activeform field into Russian?

Answer 4

As answered above, use Yii::t
in config

'language' => 'ru-RU',

'components' => [
'i18n' => [
            'translations' => [
                '*' => [
                    'sourceLanguage' => 'ru-RU',
                    'class' => 'yii\i18n\PhpMessageSource',
                    'basePath' => '@app/messages',
                    'fileMap' => [
                        'app' => 'app.php',
                        'app/error' => 'error.php',
                    ],
                ],
            ],
        ],
]

messages/ru-RU/app.php

<?php
return [
  'Create' => 'Добавить',
  'Update' => 'Обновить',
  'Delete' => 'Удалить',
  'Create {modelClass}' => 'Добавить {modelClass}',
  'Update {modelClass}' => 'Обновить {modelClass}',
]
