    <p>I have two tables:</p> <p>Branches:</p> <pre><code>+-------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | name | varchar(255) | NO | | NULL | | +-------------+--------------+------+-----+---------+----------------+ </code></pre> <p>BranchMeta:</p> <pre><code>+------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | branch_id | int(11) | YES | MUL | NULL | | | metaname | varchar(255) | NO | | NULL | | | metavalue | varchar(255) | NO | | NULL | | +------------+--------------+------+-----+---------+----------------+ </code></pre> <p>I want to have different meta fields, like "phone", "email", etc. that may be multiple as well.</p> <p>Currently I have this code (setters/getters are omitted):</p> <p>// Entity/Branch.php</p> <pre><code>&lt;?php namespace Acme\Bundle\ConsysBundle\Entity; use Doctrine\ORM\Mapping as ORM; use Doctrine\Common\Collections\ArrayCollection; /** * Branch * * @ORM\Entity(repositoryClass="Acme\Bundle\ConsysBundle\Entity\BranchRepository") * @ORM\Table(name="branch") */ class Branch { /** * @var integer * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @var string * * @ORM\Column(name="name", type="string", length=255) */ private $name; /** * * @ORM\OneToMany(targetEntity="BranchMeta", mappedBy="branch") */ private $metadata; public function __construct() { $this-&gt;metadata = new ArrayCollection(); } } ?&gt; </code></pre> <p>// Entity/BranchMeta.php</p> <pre><code>&lt;?php namespace Acme\Bundle\ConsysBundle\Entity; use Doctrine\ORM\Mapping as ORM; /** * BranchMeta * * @ORM\Entity(repositoryClass="Acme\Bundle\ConsysBundle\Entity\BranchMetaRepository") * @ORM\Table(name="branchmeta") */ class BranchMeta { /** * @var integer * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @ORM\ManyToOne(targetEntity="Branch", inversedBy="metadata") * @ORM\JoinColumn(name="branch_id", referencedColumnName="id") */ private $branch; /** * @var string * * @ORM\Column(name="metaname", type="string", length=255) */ private $name; /** * @var string * * @ORM\Column(name="metavalue", type="string", length=255) */ private $value; ?&gt; </code></pre> <p>And then I need to build a form to add a Branch like this:</p> <pre><code>Branch Name: [_________] Branch Phone: [_________] [-] Branch Phone: [_________] [+] Branch Email: [_________] [-] Branch Email: [_________] [+] [Submit] </code></pre> <p>Where "Branch Phone" fields point to branchmeta table with meta name "phone" and correspondent values, and "Branch Email" fields point to branchmeta table with meta name "email". Both can be dynamically added/deleted.</p> <p>How can I build this using Symfony2's FormBuilder? I created BranchType like this:</p> <pre><code>class BranchType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder-&gt;add('name'); } public function getName() { return 'branch'; } } </code></pre> <p>And BranchMetaType:</p> <pre><code>class BranchMetaType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder-&gt;add('name'); $builder-&gt;add('value'); } public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver-&gt;setDefaults(array( 'data_class' =&gt; 'Acme\Bundle\ConsysBundle\Entity\BranchMeta', )); } public function getName() { return 'branch_meta'; } } </code></pre> <p>But then I got stuck... How to properly use BranchMetaType to build the desired form in my case? Maybe I'm missing something in data mapping?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
