Symfony, how get current user (FOS) in entity, unused __construct()?

I have an entity Book. Title of this Book is stored in different languages ​​(the entity Book is associated with BookTranslates as OneToMane).

The entity Book is used as a form field in several places (like select). For this, I need to set __toString () for the Book entity, which will return the title of the Book in the user's language.

I tried to get the user inside the entity by passing TokenStorageInterface in the __construct () method of the Book class, but the doctrine never calls the __construct () method in that case.

Brief statement of the problem: __toString () in entity must return a field of one of the related entities. Which specifically related entities - depends on the current user. How to implement it correctly?

Solution

  • This is one of the possible solutions:

    Please leave entity __construct alone.

    I assume you have entity with translations. You entity can (should) have method like setCurrentLocale to be aware of current locale. Method can be called manually or in e.g. Doctrine2 postLoad event:

    public function setCurrentLocale(string $locale)
{
    $this->locale - $locale;
}

    Now in __toString while translating e.g. title your entity can fetch proper translation.
