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.

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
_configDelete() protected

Delete a single config key
_configRead() protected

Read a config variable
_configWrite() protected

Write a config variable

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.

Setting a specific value:

$this->config('key', $value);

Setting a nested value:

$this->config('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->config(['one' => 'value', 'another' => 'value']);

findTranslations() ¶ public

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

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.

Parameters

Cake\ORM\Query $query: The original query to modify
array $options: Options

Returns

Cake\ORM\Query

groupTranslations() ¶ public

groupTranslations(Cake\Datasource\ResultSetInterface $results): Cake\Collection\Collection

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

Parameters

Cake\Datasource\ResultSetInterface $results: Results to modify.

Returns

Cake\Collection\Collection

implementedEvents() ¶ public

implementedEvents(): array

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

implementedFinders() ¶ public

implementedFinders(): array

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() ¶ public

implementedMethods(): array

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()

Returns

array

initialize() ¶ public

initialize(array $config): void

Initialize hook

Implement this method to avoid having to overwrite the constructor and call parent.

Parameters

array $config: The config for this behavior.

Returns

void

locale() ¶ public

locale(string|null $locale = null): string

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

Parameters

string|null $locale optional: The locale to use for fetching translated records

Returns

string

setupFieldAssociations() ¶ public

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

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

Additionally it creates a i18n HasMany association that will be used for fetching all translations for each record in the bound table

Parameters

array $fields: list of fields to create associations for
string $table: the table name to use for storing each field translation
string $model: the model field value
string $strategy: the strategy used in the _i18n association

Returns

void
