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

Method Detail

__call() public 

__call(mixed $method, mixed $args)

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 $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.

configShallow() public 

configShallow(mixed $key, mixed $value)

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']);

string|array $key

The key to set, or a complete array of configs.

mixed|null $value optional

The value to set.

Returns

$this

Returns

\Cake\ORM\Behavior\Translate\TranslateStrategyInterface

findTranslations() 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.

Parameters

\Cake\ORM\Query $query

The original query to modify

array $options

Options

Returns

\Cake\ORM\Query

getConfig() public 

getConfig(?string $key, mixed $default)

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)

Returns the config for this specific key.

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

getStrategy() public 

getStrategy()

Get strategy class instance.

Returns

\Cake\ORM\Behavior\Translate\TranslateStrategyInterface

getTable() public 

getTable()

Get the table instance this behavior is bound to.

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

array

Throws

ReflectionException

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

Returns

array

Throws

ReflectionException

initialize() public 

initialize(array $config)

Initialize hook

Parameters

array $config

The config for this behavior.

referenceName() 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

\Cake\ORM\Table $table

The table class to get a reference name for.

Returns

string

setConfig() public 

setConfig(mixed $key, mixed $value, mixed $merge)

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

string|array $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\Exception
When trying to set a key that is invalid.

setDefaultStrategyClass() public static 

setDefaultStrategyClass(string $class)

Set default strategy class name.

Parameters

string $class

Class name.

setLocale() public 

setLocale(?string $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
