Doctrine2 one to many relation not showing in admin form - symfony

Question

So I (think I have done it correctly) mapped a one to many relation between two table.
The SQL to create foreign key was generated but able.the field on my admin class show form fields method is not outputting a field from the other table.
My Main Entity:
/**
* Suppliers
*
* #ORM\Table(
* name="suppliers",
* indexes={
* #Index(
* name="supplier_name", columns={"name"}
* )
* })
* #ORM\Entity
* #ORM\HasLifecycleCallbacks()
*/
class Suppliers
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer", nullable=false, options={"unsigned":true})

So when Sonata goes to show form I would like it to run the below query behind the scenes:
SELECT
*
FROM
supplier_regions sr
JOIN suppliers s ON s.id = sr.supplier_id
Here is my Supplier admin class:
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Form\FormMapper;

return $supplier;
}

I want my show form to display all the postcode entries for the a particular supplier but at the moment it's blank...
Can anyone spot what it is I need to do?
Thanks in advance :)
