Symfony2从提交的表单数据中删除id字段

My Symfony2 form has a text field containing the entity's ID.

I used the following to achieve this:

$formBuilder->add('id', TextType::class, ['attr' => ['readonly' => true]])

When submitting the form, which represents an existing entity, the ID is passed and Doctrine searches for an accessor method to modify the ID. At this point, an exception is thrown, as the entity doesn't allow to change the ID.

What is the common way in Symfony2 to provide a read-only field, which is not meant to be saved?
