/**
|
|
* The {Translatable} decorator allows your DataObjects to have versions in different languages,
|
|
* defining which fields are can be translated.
|
|
*
|
|
* Common language names (e.g. 'en') are used in {Translatable} for
|
|
* database-entities. On the other hand, the file-based i18n-translations
|
|
* always have a "locale" (e.g. 'en_US').
|
|
*
|
|
* You can enable {Translatabe} for any DataObject-subclass:
|
|
* <example>
|
|
* static $extensions = array(
|
|
* "Translatable('MyTranslatableVarchar', 'OtherTranslatableText')"
|
|
* );
|
|
* </example>
|
|
*
|
|
* 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.
|
|
*
|
|
* Caution: Further decorations of DataObject might conflict with this implementation,
|
|
* e.g. when overriding the get_one()-calls (which are already extended by {Translatable}).
