    <p>I'm running a Symfony 2.4 project with Doctrine 2.4 and having some issues with form creation/validation.</p> <p>I have an entity "Person" with a <strong>OneToOne-Relation</strong> to an "Address" entity (unidirectional) - so the person can have one or none addresses.</p> <pre><code>/** * @var Address * @ORM\OneToOne(targetEntity="Koala\AddressBundle\Entity\Address", cascade={"all"}) * @Assert\Valid */ private $address; public function setAddress(Address $address = null) { $this-&gt;address = $address; } </code></pre> <p>In my PersonType class for the form rendering I have added the code as follows:</p> <pre><code>$builder-&gt;add('address', AddressType::SERVICE_NAME, array( 'label' =&gt; 'address._label', 'required' =&gt; false ) ); </code></pre> <p>Loading/Displaying a Person-entity that doesn't have an Address works fine - i.e. no fields are shown for the address because in my Twig-template I have: </p> <pre><code>{% if form.address.vars.value|default is not empty %} {# address form here #} {% endif %} </code></pre> <p>Also loading the edit form works fine, i.e. no address form is shown, as I don't want to have an address in that place of the App (but in general Person could have an address).</p> <p>The problem now is, as soon as I change something in the persons form and submit the changes to the server, form validation fails because Symfony creates a new empty Address object for which the validation fails because there are some mandatory fields in an Address. But here I explicitly don't want an address. I thought that having the if-condition (see above) should solve this. Because using two different twig-templates that quite look the same - just one not having an address seemed ugly to me and would violate the <a href="http://en.wikipedia.org/wiki/DRY_principle" rel="nofollow">DRY-Principle</a>.</p> <p>What am I doing wrong?<br> How can I stop Symfony from creating an empty Address-object for a person?</p> <p><strong>EDIT:</strong><br> For better clarification, here the code of the controller method handling edit:</p> <pre><code>public function editAction($id, $version, Request $request) { try { $company = $this-&gt;companyRepository-&gt;find($id, LockMode::PESSIMISTIC_WRITE, $version); $routeId = array('id' =&gt; $id, 'version' =&gt; $company-&gt;getVersion()); $form = $this-&gt;createForm(CompanyType::SERVICE_NAME, $company, array( 'action' =&gt; $this-&gt;router-&gt;generate('replaced_for_stackoverflow', $routeId), 'method' =&gt; 'POST') ); if ($request-&gt;isMethod('POST')) { $form-&gt;handleRequest($request); if ($form-&gt;isValid()) { // If isValid() were true, entity changes would get saved. } // But: isValid() is false, because there is an Address-Entity in one of the Person-entities attached to the company-entity. And this is because Symfony creates an Address-Instance by itself. And I don't know how to turn this behavior off. } } // Rest of method left out as irrelevant to the problem. } </code></pre>

    1. COIt might help if you posted the error message. Have you tried `entity->setAddress()` before persist in your controller updateAction?

    2. COThe error message is that validation of Address-Entity fails because two fields in the Address-Entity are empty. But I don't want any Address-Entity at all - unless I create one explicitly. I don't want Symfony to create an empty Address-Entity for me. I'm not persisting yet - the error is before. I updated the question above with some controller code - hope that clarifies the problem.

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).
