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.

implementedEvents() ¶ public
implementedEvents(): array
Gets the Model callbacks this behavior is interested in.

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

$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.

When trying to set a key that is invalid.
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
