Persist link in One-to-many / many-to-many - Doctrine and Symfony2 - php

Question

I had a many-to-many using a User and Account entity. I needed to add an isOwner field to the association table so I changed it to a one-to-many / many-to-one relation. Below are my 3 entities (user, account, useraccount).
When I persist the user, the user record and account record are both added, but the association record is not. I am also unsure as to how I can set the isOwner field whilst persisting the user.
Does anyone know how the association record can be persisted? Should the association record be added automatically?

Controller:
$account = new Account();
$account->setName('Test account');
$user = new User();
$user->setFirstName('John');
$user->addAccount($account);
$manager->persist($user);
$manager->flush();

Answer 1

You are trying to persist an account as UserAccount entity. Try this:
$account = new Account();
$account->setName('Test account');
$user = new User();
$user->setFirstName('John');
$user_account = new UserAccount();
$user_account->setAccount($account);
$user_account->setUser($user);
$manager->persist($user);
$manager->flush();
