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 Detail

__call() ¶ public

__call(string $method, array $args): mixed

Proxy method calls to strategy class instance.

Parameters

string $method: Method name.
array $args: Method arguments.

Returns

mixed

__construct() ¶ public

__construct(Cake\ORM\Table $table, array<string, mixed> $config = [])

Constructor

Options

fields: List of fields which need to be translated. Providing this fields list is mandatory when using EavStrategy. If the fields list is empty when using ShadowTableStrategy then the list will be auto generated based on shadow table schema.
defaultLocale: The locale which is treated as default by the behavior. Fields values for defaut locale will be stored in the primary table itself and the rest in translation table. If not explicitly set the value of I18n::getDefaultLocale() will be used to get default locale. If you do not want any default locale and want translated fields for all locales to be stored in translation table then set this config to empty string ''.
allowEmptyTranslations: By default if a record has been translated and stored as an empty string the translate behavior will take and use this value to overwrite the original field value. If you don't want this behavior then set this option to false.
validator: The validator that should be used when translation records are created/modified. Default null.

Parameters

Cake\ORM\Table $table: The table this behavior is attached to.
array<string, mixed> $config optional: The config for this behavior.

Merge provided config with existing config. Unlike config() which does a recursive merge for nested keys, this method does a simple merge.

Setting a specific value:

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

Setting a nested value:

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

Updating multiple config settings at the same time:

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

Cake\ORM\Behavior\Translate\TranslateStrategyInterface

findTranslations() ¶ public

findTranslations(Cake\ORM\Query $query, array<string, mixed> $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<string, mixed> $options: Options

Returns

Cake\ORM\Query

getConfig() ¶ public

getConfig(string|null $key = null, mixed $default = null): mixed

Returns the config.

Usage

Reading the whole config:

$this->getConfig();

Reading a specific value:

$this->getConfig('key');

Reading a nested value:

$this->getConfig('some.nested.key');

Reading with default value:

$this->getConfig('some-key', 'default-value');

Parameters

string|null $key optional: The key to get or null for the whole config.
mixed $default optional: The return value when the key does not exist.

Returns

mixed

Configuration data at the named key or null if the key does not exist.

getConfigOrFail() ¶ public

getConfigOrFail(string $key): mixed

Returns the config for this specific key.

The config value for this key must exist, it can never be null.

Parameters

string $key: The key to get.

Returns

mixed

Configuration data at the named key

Throws

InvalidArgumentException

getDefaultStrategyClass() ¶ public static

getDefaultStrategyClass(): string

Get default strategy class name.

Returns

string

getLocale() ¶ public

getLocale(): string

Returns the current locale.

If no locale has been explicitly set via setLocale(), this method will return the currently configured global locale.

Returns

string

getStrategy() ¶ public

getStrategy(): Cake\ORM\Behavior\Translate\TranslateStrategyInterface

Get strategy class instance.

Returns

Cake\ORM\Behavior\Translate\TranslateStrategyInterface

getTable() ¶ public

getTable(): Cake\ORM\Table

Get the table instance this behavior is bound to.

Returns

Cake\ORM\Table

The bound table instance.

implementedEvents() ¶ public

implementedEvents(): array<string, mixed>

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<string, mixed>

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

Throws

ReflectionException

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

Throws

ReflectionException

initialize() ¶ public

initialize(array<string, mixed> $config): void

Initialize hook

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

Parameters

array<string, mixed> $config: The config for this behavior.

Returns

void

referenceName() ¶ protected

referenceName(Cake\ORM\Table $table): string

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

Cake\ORM\Table $table: The table class to get a reference name for.

Returns

string

setConfig() ¶ public

setConfig(array<string, mixed>|string $key, mixed|null $value = null, bool $merge = true): $this

Sets the config.

Usage

Setting a specific value:

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

Setting a nested value:

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

Updating multiple config settings at the same time:

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

Parameters

array<string, mixed>|string $key: The key to set, or a complete array of configs.
mixed|null $value optional: The value to set.
bool $merge optional: Whether to recursively merge or overwrite existing config, defaults to true.

Returns

$this

Throws

Cake\Core\Exception\CakeException
When trying to set a key that is invalid.

setDefaultStrategyClass() ¶ public static

setDefaultStrategyClass(string $class): void

Set default strategy class name.

Parameters

string $class: Class name.

Returns

void

setLocale() ¶ public

setLocale(string|null $locale): $this

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
