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.

Method Summary

  • __construct() public
    Constructor
  • Helper method used to generated multiple translated field entities out of the data found in the _translations property in the passed entity. The result will be put into its _i18n property

  • Returns the ids found for each of the condition arrays passed for the translations table. Each records is indexed by the corresponding position to the conditions array

  • _referenceName() protected
    Determine the reference name to use for a given table
  • _rowMapper() protected

    Modifies the results from a table find in order to merge the translated fields into each entity for a given locale.

  • afterSave() public
    Unsets the temporary _i18n property after the entity has been saved
  • beforeFind() public

    Callback method that listens to the beforeFind event in the bound table. It modifies the passed query by eager loading the translated fields and adding a formatter to copy the values into the main table records.

  • beforeSave() public

    Modifies the entity before it is saved so that translated fields are persisted in the database too.

  • Add in _translations marshalling handlers if translation marshalling is enabled. You need to specifically enable translation marshalling by adding 'translations' => true to the options provided to Table::newEntity() or Table::patchEntity().

  • Custom finder method used to retrieve all translations for the found records. Fetched translations can be filtered by locale by passing the locales key in the options array.

  • Modifies the results from a table find in order to merge full translation records into each entity under the _translations key

  • initialize() public
    Initialize hook
  • locale() public

    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

  • Creates the associations between the bound table and every field passed to this method.

  • Returns a fully aliased field name for translated fields.

__construct( Cake\ORM\Table $table , array $config [] )

Constructor

Parameters

Cake\ORM\Table $table
The table this behavior is attached to.
array $config optional []
The config for this behavior.

Overrides

Cake\ORM\Behavior::__construct()

_bundleTranslatedFields()source protected

_bundleTranslatedFields( Cake\Datasource\EntityInterface $entity )

_referenceName()source protected

_referenceName( Cake\ORM\Table $table )

Determine the reference name to use for a given table

The reference name is usually derived from the class name of the table object (PostsTable -> Posts), however for autotable instances it is derived from the database table the object points at - or as a last resort, the alias of the autotable instance.

Parameters

The table class to get a reference name for.

Returns

string

_rowMapper()source protected

_rowMapper( Cake\Datasource\ResultSetInterface $results , string $locale )

Parameters

Cake\Datasource\ResultSetInterface $results
Results to map.
string $locale
Locale string

Returns

Cake\Collection\CollectionInterface

afterSave()source public

The entity that is going to be saved

beforeFind()source public

beforeFind( Cake\Event\Event $event , Cake\ORM\Query $query , ArrayObject $options )

Callback method that listens to the beforeFind event in the bound table. It modifies the passed query by eager loading the translated fields and adding a formatter to copy the values into the main table records.

The entity that is going to be saved
ArrayObject $options
the options passed to the save method

buildMarshalMap()source public

buildMarshalMap( Cake\ORM\Marshaller $marshaller , array $map , array $options )

Add in _translations marshalling handlers if translation marshalling is enabled. You need to specifically enable translation marshalling by adding 'translations' => true to the options provided to Table::newEntity() or Table::patchEntity().

Implementation of

Cake\ORM\PropertyMarshalInterface::buildMarshalMap()

findTranslations()source public

findTranslations( Cake\ORM\Query $query , array $options )

Custom finder method used to retrieve all translations for the found records. Fetched translations can be filtered by locale by passing the locales 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.

array $options
Options

Returns

Cake\ORM\Query

groupTranslations()source public

The locale to use for fetching translated records

Returns

string

setupFieldAssociations()source public

setupFieldAssociations( array $fields , string $table , string $model , string $strategy )

Field name to be aliased.

Returns

string

Methods inherited from Cake\ORM\Behavior

_reflectionCache()source protected

_reflectionCache( )

Gets the methods implemented by this behavior

Uses the implementedEvents() method to exclude callback methods. Methods starting with _ will be ignored, as will methods declared on Cake\ORM\Behavior

Returns

array

_resolveMethodAliases()source protected

_resolveMethodAliases( string $key , array $defaults , array $config )

Removes aliased methods that would otherwise be duplicated by userland configuration.

Parameters

string $key
The key to filter.
array $defaults
The default method mappings.
array $config
The customized method mappings.

Returns

array
A de-duped list of config data.

getTable()source public

getTable( )

Get the table instance this behavior is bound to.

Returns

Cake\ORM\Table
The bound table instance.

implementedEvents()source public

implementedEvents( )

Gets the Model callbacks this behavior is interested in.

By defining one of the callback methods a behavior is assumed to be interested in the related event.

Override this method if you need to add non-conventional event listeners. Or if you want your behavior to listen to non-standard events.

Returns

array

Implementation of

Cake\Event\EventListenerInterface::implementedEvents()

implementedFinders()source 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

array

implementedMethods()source 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

Returns

array

verifyConfig()source public

verifyConfig( )

verifyConfig

Checks that implemented keys contain values pointing at callable.

Throws

Cake\Core\Exception\Exception
if config are invalid
