(Yii2) What's the best way to deal with user avatars?

Question

Yii

1) Should the methods for working with the avatar be separated from the User Model ?
2) Where should the methods be located?
3) How can the User Model access them, and should it even have access to them?

Answer 1

1) Desirable.
2) In a separate class.
3) You can do it in different ways. For convenience, I would do something like this:

class AvatarManager
{
}

class User
{
    private $avatarManager;

    protected function getAvatarManager()
    {
        // здесь можно устроить и честный dependency injection, если планируется писать
        // честные модульные тесты или есть подозрения, что менеджеров будет не один
        return $this->avatarManager === null ? new AvatarManager($this) : $this->avatarManager;
    }

    public function getAvatarUrl($width, $height)
    {
         return $this->getAvatarManager()->getUrl($width, $height);
    }
}
