Is it a ok to create object in DAO

I have a DAO, for example, for accessing database of tokens. Is it OK to use it co create and immediately persist new entities, like in the example below? (sample in PHP)

class TokenDao {
    ...
    public function createToken($code) {
        $token = new Token($code);
        $this->entityManager->persist($token);
        $this->entityManager->flush();
        return $token;
    }
}

It combines an object factory with DAO a bit. I think making separate object factory and dao (and probably wrapping into facade) is unnecessary overhead, but I'd like to hear from others if this isn't a bad practice.

I haven't found any positive or negative clues over articles about DAO pattern if this is ok or not.

Thanks for opinions/answers.
