Symfony 3 - Using ManyToOne and OneToMany and retrieving the data - doctrine

Question

I have a User table and a Job Title table in my database.
I have setup a User entity and a JobTitle entity.
In my User entity I have:
/**
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\JobTitle", inversedBy="users")
* #ORM\JoinColumn(name="job_title_id", referencedColumnName="id")
*/
public $jobTitle;
In my JobTitle entity I have:
/**
* #ORM\OneToMany(targetEntity="AppBundle\Entity\User", mappedBy="jobTitle")
*/
private $users;
Here is an example setup in User Table:
job_title_id | Username
1 | jdoe
Here is an example setup in job Title Table:
id | job_title
1 | Owner
When I create the user everything is entered into the database as expected.
My issue is displaying the actual job title in my users list page.
Here is my Controller:
/**
* #Route("/users", name="users")
*/
public function listAction()
{
$loggedInUser = $this->getUser();
$users = $this->get('fos_user.user_manager')->findUsers();
if (!is_object($user) || !$user instanceof UserInterface) {
throw new AccessDeniedException('This user does not have access to this section.');
}
return $this->render('users/users.html.twig', array(
'user' => $loggedInUser,
'users' => $users,
));
}
In my twig template I was trying to use {{ user.jobTitle }}, but I get a conversion to string error which makes sense, but I have not idea how to get the actual job title name to display in the twig page.
If you need more info please let me know.
How do I retrieve the job title name using the job_title_id in the users table?

You haven't shown all your entities, so I'll have to 'guess' based on what I see above.
Looks like this: {{ user.jobTitle }} returns you a JobTitle object. You can confirm by doing a dump.
Since it's an object, I suspect you'll need to do something like this:
{{ user.jobTitle.job_title }}
Or possibly use the JobTitle's object methods (don't know what they are):
{{ user.jobTitle.getJobTitle }}
Or something like that. Try it out.
