Force a field to not be required
提问by ElPiter
I am using Symfony2 and FOSUserBundle.
我正在使用 Symfony2 和 FOSUserBundle。
Just as detailed in the documentation, I have overridden and created a "name" property in the User entity.
正如文档中所详述的那样，我在用户实体中覆盖并创建了一个“名称”属性。
I do all necessary and finally get that field to be shown in the form view.
我做了所有必要的事情，最后让该字段显示在表单视图中。
The thing is: when I go form_widget(form.name)and the input html tag is generated, a required="required" property is generated within it. And that causes the engine to red the input when the field is not filled in.
问题是：当我去form_widget(form.name)并生成输入 html 标签时，会在其中生成一个 required="required" 属性。这会导致引擎在未填写该字段时将输入变为红色。
How do I do to tell the Symfony2 not to make that field mandatory? I guess that it has to be here:
我该如何告诉 Symfony2 不要将该字段设为必填项？我想它必须在这里：
parent::buildForm($builder, $options);
// add your custom field
$builder->add('name', 'text', array('label' => 'form.name'));
$builder->remove('username');
or here:
或在这里：
/**
* @ORM\Column(type="string", length="255")
*
* @Assert\MinLength(limit="0", message="The name is too short.", groups={"Registration", "Profile"})
* @Assert\MaxLength(limit="255", message="The name is too long.", groups={"Registration", "Profile"})
*/
private $name;

Try to use:
尝试使用：
use Symfony\Component\Validator\Constraints\NotNull;
$builder->add('name', 'text', array('label' => 'form.name',
'constraints' => new NotNull()));
