Class TranslateBehavior
This behavior provides a way to translate dynamic data by keeping translations in a separate table linked to the original record from another one. Translated fields can be configured to override those in the main table when fetched or put aside into another property for the same entity.
If you wish to override fields, you need to call the locale
method in this
behavior for setting the language you want to fetch from the translations table.
If you want to bring all or certain languages for each of the fetched records,
you can use the custom translations
finders that is exposed to the table.

key
in the options array.
Translated values will be found for each entity under the property _translations
,
containing an array indexed by locale name.
Example:
$article = $articles->find('translations', ['locales' => ['eng', 'deu'])->first(); $englishTranslatedFields = $article->get('_translations')['eng'];
If the locales
array is not passed, it will bring all translations found
for each record.
Parameters

$query - The original query to modify
- array $options
- Options
Returns
getLocale() public ¶
getLocale( )
Returns the current locale.
If no locale has been explicitly set via setLocale()
, this method will return
the currently configured global locale.
Returns

\Cake\ORM\Behavior\TranslateBehavior::setLocale()

Initialize hook
Parameters
- array $config

Overrides
locale() public ¶
locale( string|null $locale null )
Sets all future finds for the bound table to also fetch translated fields for the passed locale. If no value is passed, it returns the currently configured locale
Deprecated
Parameters
- string|null $locale optional null
- The locale to use for fetching translated records
Returns
setLocale() public ¶
setLocale( string|null $locale )
Sets the locale that should be used for all future find and save operations on the table where this behavior is attached to.
When fetching records, the behavior will include the content for the locale set via this method, and likewise when saving data, it will save the data in that locale.
Note that in case an entity has a _locale
property set, that locale will win
over the locale set via this method (and over the globally configured one for
that matter)!
Parameters
- string|null $locale
The locale to use for fetching and saving records. Pass
null
in order to unset the current locale, and to make the behavior fall back to using the globally configured locale.
Returns
$this

implementedFinders() public ¶
implementedFinders( )
implementedFinders
Provides an alias->methodname map of which finders a behavior implements. Example:
[ 'this' => 'findThis', 'alias' => 'findMethodName' ]
With the above example, a call to $Table->find('this')
will call $Behavior->findThis()
and a call to $Table->find('alias')
will call $Behavior->findMethodName()
It is recommended, though not required, to define implementedFinders in the config property of child classes such that it is not necessary to use reflections to derive the available method list. See core behaviors for examples
Returns
Throws
implementedMethods() public ¶
implementedMethods( )
implementedMethods
Provides an alias->methodname map of which methods a behavior implements. Example:
[ 'method' => 'method', 'aliasedmethod' => 'somethingElse' ]
With the above example, a call to $Table->method()
will call $Behavior->method()
and a call to $Table->aliasedmethod()
will call $Behavior->somethingElse()
It is recommended, though not required, to define implementedFinders in the config property of child classes such that it is not necessary to use reflections to derive the available method list. See core behaviors for examples
