Symfony 2 form validation - extending request - php

Question

Im using FOSRestBundle to build a REST API in Symfony.
In my tax Controller i have:
private function processForm(Request $request, Tax $tax )
{
$form = $this->createForm(new TaxType(),$tax);
$req = $request->request->all();
$form->submit($req['tax']);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($tax);
$em->flush();
return $this->getTaxAction($tax->getId());
}
return array(
'form' => $form,
'request' => $request->request->all()
);
}
This function called from the POST and PUT functions.
TaxType
class TaxType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('createDate')
->add('writeDate')
->add('name')
->add('amount')
->add('active')
->add('createUid')
->add('writeUid')
->add('company')
;
}
...
It worked fine so far, but now i added some extra column to the table (and proprty to the Tax Entity) like: to which company belongs the record, date of creation. This wont come from the client but set on server side.
How do i add eg createData?
I have tried
$req['tax']['createDate'] = new \DateTime("now");
but im getting:
{"code":400,
"message":"Validation Failed",
"errors":{"children":{"createDate":{"errors":["This value is not valid."],
"children":{"date":{"children":{"year":[],"month":[],"day":[]}},
"time":{"children":{"hour":[],"minute":[]}}}},
"writeDate":{"children":{"date":{"children":{"year":[],"month":[],"day":[]}},
"time":{"children":{"hour":[],"minute":[]}}}},"name":[],"amount":[],"active":[],"createUid":[],"writeUid":[],"company":[]}}}
from entity Tax.php
/**
* #var \DateTime
*/
private $createDate;
I guess im extending the request with the correct data type, but im getting validation error.

Answer 1

If I understand the question correctly you don't have to take the request but just change the property on the $tax-object.
You can also do this after the form validation if you want.

Answer 2

You can Remove add('createDate') from your form builder.
$builder
->add('createDate')
->add('writeDate')
->add('name')
->add('amount')
->add('active')
->add('createUid')
->add('writeUid')
->add('company')
Then set the createdDate value on your $tex object before persist.
if ($form->isValid()) {
$tax->setCreateDate(new \DateTime("now"));
$em = $this->getDoctrine()->getManager();
$em->persist($tax);
$em->flush();
return $this->getTaxAction($tax->getId());
}
Alternative Method
Or you can use Doctrine's Lifecycle Callbacks to achieve this.
Happy coding!!
