Class yii\mongodb\i18n\MongoDbMessageSource

Inheritance	yii\mongodb\i18n\MongoDbMessageSource » yii\i18n\MessageSource » yii\base\Component » yii\base\Object
Implements	yii\base\Configurable
Available since version	2.0.5
Source Code	https://github.com/yiisoft/yii2-mongodb/blob/master/i18n/MongoDbMessageSource.php

MongoDbMessageSource extends yii\i18n\MessageSource and represents a message source that stores translated messages in MongoDB collection.

This message source uses single collection for the message translations storage, defined via $collection. each entry in this collection should have 3 fields:

• language: string, translation language
• category: string, name translation category
• messages: array, list of actual message translations, in each element: the key is raw message name value - message translation.

For example:

{
    "category": "app",
    "language": "de",
    "messages": {
        "Hello world!": "Hallo Welt!",
        "The dog runs fast.": "Der Hund rennt schnell.",
        ...
    },
}

Property Details

$cache public property

The cache object or the application component ID of the cache object. The messages data will be cached using this cache object. Note, that to enable caching you have to set $enableCaching to true, otherwise setting this property has no effect.

After the MongoDbMessageSource object is created, if you want to change this property, you should only assign it with a cache object.

This can also be a configuration array for creating the object.

See also:

• $cachingDuration
• $enableCaching

public yii\caching\Cache|array|string $cache = 'cache'

$cachingDuration public property

The time in seconds that the messages can remain valid in cache. Use 0 to indicate that the cached data will never expire.

See also $enableCaching.

public integer $cachingDuration = 0

$collection public property

The name of the MongoDB collection, which stores translated messages. This collection is better to be pre-created with fields 'category' and 'language' indexed.

public string|array $collection = 'message'

$db public property

The MongoDB connection object or the application component ID of the MongoDB connection.

After the MongoDbMessageSource object is created, if you want to change this property, you should only assign it with a MongoDB connection object.

This can also be a configuration array for creating the object.

public yii\mongodb\Connection|array|string $db = 'mongodb'

$enableCaching public property

Whether to enable caching translated messages

public boolean $enableCaching = false
