/**
|
||||
* Migrates the old Translatable datamodel introduced in SilverStripe 2.1 to the new schema
|
||||
* introduced in SilverStripe 2.3.2.
|
||||
* Just works for {@link SiteTree} records and subclasses. If you have used the Translatable
|
||||
* extension on other {@link DataObject} subclasses before, this script won't migrate them automatically.
|
||||
*
|
||||
* <h2>Limitations</h2>
|
||||
*
|
||||
* - Information from the {@link Versioned} extension (e.g. in "SiteTree_versions" table)
|
||||
* will be discarded for translated records.
|
||||
* - Custom translatable fields on your own {@link Page} class or subclasses thereof won't
|
||||
* be migrated into the translation.
|
||||
* - 2.1-style subtags of a language (e.g. "en") will be automatically disambiguated to their full
|
||||
* locale value (e.g. "en_US"), by the lookup defined in {@link i18n::get_locale_from_lang()}.
|
||||
* - Doesn't detect published translations when the script is run twice on the same data set
|
||||
*
|
||||
* <h2>Usage</h2>
|
||||
*
|
||||
* PLEASE BACK UP YOUR DATABASE BEFORE RUNNING THIS SCRIPT.
|
||||
*
|
||||
* Warning: Please run dev/build on your 2.2 database to update the schema before running this task.
|
||||
* The dev/build command will rename tables like "SiteTree_lang" to "_obsolete_SiteTree_lang".
|
||||
*
|
||||
* <h3>Commandline</h3>
|
||||
* Requires "sake" tool (see http://doc.silverstripe.com/?id=sake)
|
||||
* <example>
|
||||
* sake dev/tasks/MigrateTranslatableTask
|
||||
* </example>
