Question

I have the class User as the base class then i extended Teacher from user class.

When i try to login i get this error

You cannot refresh a user from the EntityUserProvider that does not
contain an identifier. The user object has to be serialized with its
own identifier mapped by Doctrine.

I have serialize/deserialize function in user.php as i have coped that from FOSUserbundle

public function serialize()
    {
        return serialize(array(
            $this->password,
            $this->salt,
            $this->usernameCanonical,
            $this->username,
            $this->expired,
            $this->locked,
            $this->credentialsExpired,
            $this->enabled,
        ));
    }

I am not able to find where i can check for error. i am stuck. please help

Answer 1

From the code of EntityUserProvider.php it seems that you have to serialize id of the user also.
