/**
|
|
* The Translatable decorator allows your DataObjects to have versions in different languages,
|
|
* defining which fields are can be translated. Translatable can be applied
|
|
* to any {@link DataObject} subclass, but is mostly used with {@link SiteTree}.
|
|
* Translatable is compatible with the {@link Versioned} extension.
|
|
* To avoid cluttering up the database-schema of the 99% of sites without multiple languages,
|
|
* the translation-feature is disabled by default.
|
|
*
|
|
* Locales (e.g. 'en_US') are used in Translatable for identifying a record by language,
|
|
* see section "Locales and Language Tags".
|
|
*
|
|
* <h2>Configuration</h2>
|
|
*
|
|
* <h3>Through Object::add_extension()</h3>
|
|
* Enabling Translatable through {@link Object::add_extension()} in your _config.php:
|
|
* <code>
|
|
* Object::add_extension('MyClass', 'Translatable');
|
|
* </code>
|
|
* This is the recommended approach for enabling Translatable.
|
|
*
|
|
* <h3>Through $extensions</h3>
|
|
* <code>
|
|
* class MyClass extends DataObject {
|
|
* static $extensions = array(
|
|
* "Translatable"
|
|
* );
|
|
* }
|
|
* </code>
|
|
*
|
|
* Make sure to rebuild the database through /dev/build after enabling translatable.
|
|
* Use the correct {@link set_default_locale()} before building the database
|
|
* for the first time, as this locale will be written on all new records.
|
|
*
|
|
* <h3>"Default" locales</h3>
|
|
*
|
|
* Important: If the "default language" of your site is not US-English (en_US),
|
|
* please ensure to set the appropriate default language for
|
|
* your content before building the database with Translatable enabled:
|
|
* <code>
|
|
* Translatable::set_default_locale(<locale>); // e.g. 'de_DE' or 'fr_FR'
|
|
* </code>
|
|
*
|
|
* For the Translatable class, a "locale" consists of a language code plus a region code separated by an underscore,
|
|
* for example "de_AT" for German language ("de") in the region Austria ("AT").
|
|
* See http://www.w3.org/International/articles/language-tags/ for a detailed description.
|
|
*
|
|
* <h2>Usage</h2>
|
|
*
|
|
* Getting a translation for an existing instance:
|
|
* <code>
|
|
* $translatedObj = Translatable::get_one_by_locale('MyObject', 'de_DE');
|
|
* </code>
|
|
*
|
|
* Getting a translation for an existing instance:
|
|
* <code>
|
|
* $obj = DataObject::get_by_id('MyObject', 99); // original language
|
|
* $translatedObj = $obj->getTranslation('de_DE');
|
|
* </code>
|
|
*
|
|
* Getting translations through {@link Translatable::set_current_locale()}.
|
|
* This is *not* a recommended approach, but sometimes inavoidable (e.g. for {@link Versioned} methods).
|
|
* <code>
|
|
* $origLocale = Translatable::get_current_locale();
|
|
* Translatable::set_current_locale('de_DE');
|
|
* $obj = Versioned::get_one_by_stage('MyObject', "ID = 99");
|
|
* Translatable::set_current_locale($origLocale);
|
|
* </code>
|
|
*
|
|
* Creating a translation:
|
|
* <code>
|
|
* $obj = new MyObject();
|
|
* $translatedObj = $obj->createTranslation('de_DE');
|
|
* </code>
|
|
*
|
|
* <h2>Usage for SiteTree</h2>
|
|
*
|
|
* Translatable can be used for subclasses of {@link SiteTree} as well.
|
|
*
|
|
* <code>
|
|
* Object::add_extension('SiteTree', 'Translatable');
|
|
* Object::add_extension('SiteConig', 'Translatable');
|
|
* </code>
|
|
*
|
|
* If a child page translation is requested without the parent
|
|
* page already having a translation in this language, the extension
|
|
* will recursively create translations up the tree.
|
|
* Caution: The "URLSegment" property is enforced to be unique across
|
|
* languages by auto-appending the language code at the end.
|
|
* You'll need to ensure that the appropriate "reading language" is set
|
|
* before showing links to other pages on a website through $_GET['locale'].
|
|
* Pages in different languages can have different publication states
|
|
* through the {@link Versioned} extension.
|
|
*
|
|
* Note: You can't get Children() for a parent page in a different language
|
|
* through set_current_locale(). Get the translated parent first.
|
|
*
|
|
* <code>
|
|
* // wrong
|
|
* Translatable::set_current_locale('de_DE');
|
|
* $englishParent->Children();
|
|
* // right
|
|
* $germanParent = $englishParent->getTranslation('de_DE');
|
|
* $germanParent->Children();
|
|
* </code>
|
|
*
|
|
* <h2>Translation groups</h2>
|
|
*
|
|
* Each translation can have one or more related pages in other languages.
|
|
* This relation is optional, meaning you can
|
|
* create translations which have no representation in the "default language".
|
|
* This means you can have a french translation with a german original,
|
|
* without either of them having a representation
|
|
* in the default english language tree.
|
|
* Caution: There is no versioning for translation groups,
|
|
* meaning associating an object with a group will affect both stage and live records.

* SiteTree database table (abbreviated)

* | 199 | 3 |
|
|
*
|
|
* <h2>Character Sets</h2>
|
|
*
|
|
* Caution: Does not apply any character-set conversion, it is assumed that all content
|
|
* is stored and represented in UTF-8 (Unicode). Please make sure your database and
|
|
* HTML-templates adjust to this.
|
|
*
|
|
* <h2>Permissions</h2>
|
|
*
|
|
* Authors without administrative access need special permissions to edit locales other than
|
|
* the default locale.
|
|
*
|
|
* - TRANSLATE_ALL: Translate into all locales
|
|
* - Translate_<locale>: Translate a specific locale. Only available for all locales set in
|
|
* `Translatable::set_allowed_locales()`.
|
|
*
|
|
* Note: If user-specific view permissions are required, please overload `SiteTree->canView()`.
|
|
*
|
|
* <h2>Uninstalling/Disabling</h2>
|
|
*
|
|
* Disabling Translatable after creating translations will lead to all
|
|
* pages being shown in the default sitetree regardless of their language.
|
|
* It is advised to start with a new database after uninstalling Translatable,
|
|
* or manually filter out translated objects through their "Locale" property
|
|
* in the database.
