symfony2: Removing username from FOSUserBundle registration form not working

我正试图从FOSUserBundle注册表中删除用户名字段，如本答案中的步骤2所述。

这是我创建的FormType类，用于覆盖默认值：

<?php
// src/UserBundle/Form/Type/RegistrationFormType.php
namespace UserBundle'Form'Type;
use FOS'UserBundle'Form'Type'RegistrationFormType as BaseFormType;
class RegistrationFormType extends BaseFormType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        parent::buildForm($builder, $options);
        $builder->remove('username');
    }
}

但是，用户名字段仍然显示在表单中。我错过了什么？

您没有覆盖捆绑包配置中的表单服务。

这就是FOSUserBundle不使用您的表单类型的原因。

# register your form-type as a service ...
services:
    my_custom_user_registration_form:
        class:  "UserBundle'Form'Type'RegistrationFormType"
# ... then tell FOSUserBundle to use this form-type service instead of the default
fos_user:
    ...
    registration:
        form:
            type: my_custom_user_registration_form
