Question

我目前正在使用select2 v4，因为现在需要选择而不是输入我在验证选项时遇到问题，因为我通过ajax加载这些选项。

我安装了tetranz / select2entity-bundle（https://github.com/tetranz/select2entity-bundle）。我完全按照说明操作，我现在在安装后收到此错误：

 The option "multiple" does not exist. Known options are: "action", "attr", 
"auto_initialize", "block_name", "by_reference", "cascade_validation", 
"compound", "constraints", "csrf_field_name", "csrf_message", 
"csrf_protection", "csrf_provider", "csrf_token_id", "csrf_token_manager", 
"data", "data_class", "disabled", "empty_data", "error_bubbling", 
"error_mapping", "extra_fields_message", "inherit_data", "intention", 
"invalid_message", "invalid_message_parameters", "label", "label_attr", 
"mapped", "max_length", "method", "pattern", "post_max_size_message", 
"property_path", "read_only", "required", "translation_domain", "trim", 
"validation_groups", "virtual"

500 Internal Server Error - InvalidOptionsException

除了安装我的表单构建器 - ＆gt;添加如下所示：

       ->add('receiver_physician', 'tetranz_select2entity', array(
           'multiple' => false,
           'remote_route' => 'ajax_physician_search_by_term',
           'class' => '\HospitalBundle\Entity\Physician',
           'text_property' => 'name',
           'minimum_input_length' => 2,
           'page_limit' => 10,
           'placeholder' => 'Select a Physician',
       ))

其他人有这个问题吗？

与tetranz_select2entity相关联的类具有configureOptions（）方法。它是在Symfony 2.7中引入的。以前，该方法称为setDefaultOptions（）。

作为止损，我将以下内容添加到Select2EntityType：

/**
 * @param OptionsResolverInterface $resolver
 */
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $this->configureOptions($resolver);
}

（＆＃34;使用＆＃34;声明也需要。作者要遵循的贡献。）
