Symfony2-无法访问字符串变量（“内联”）上的属性（“日期”）

Question

I have create a entity "Fact" width "date" attribute.

/**
 * Fact
 *
 * @ORM\Table(name="fact")
 * @ORM\Entity()
 */
class Fact
{
   .....

    /**
     * @var \DateTime
     *
     * @ORM\Column(name="date", type="datetime")
     */
    private $date;

    /**
     * Get date
     *
     * @return \DateTime 
     */
    public function getDate()
    {
        return $this->date;
    }

    ...
}

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('date', 'date')        
    }

Than i create its CRUD interfaces with symfony command (also i use bootstrapSymfonyBundle):

php app/console generate:doctrine:crud --entity=MlatAdminBundle:Fact --format=annotation

So i got this error:

Impossible to access an attribute ("date") on a string variable ("inline") in ... /vendor/braincrafted/bootstrap-bundle/Bc/Bundle/BootstrapBundle/Resources/views/Form/form_div_layout.html.twig at line 189 

I think that the return type of getDate() function is the problem. I casted it in DateTime Object but nothing change.

Answer 1

/**
 * @ORM\Column(type="datetime", name="date")
 * @Gedmo\Timestampable(on="create")
 */
private $date;

try to change your code with this. Also add use Gedmo\\Mapping\\Annotation as Gedmo; in the top of your code. If you don't have gedmo vendor, install it. After install, you can use that code.
