Question

我有字段customers - 下拉现有客户。并且有客户，比如CollectionType，'entry_type' => CustomerForm::class,但是我使用了ManyToMany关系的示例，但我的关系ManyToOne和我需要为我的表单更改逻辑，需要在CustomerForm::class中只创建一个客户我阅读了烹饪书form_collections当我添加新的客户表单时，如CollectionType::class，提交表单时出错

Expected argument of type "AppBundle\Entity\Customer", "array" given

请求中的

economy_bundle_outbound_invoice = {array} [4]
companyReference = "wwwww"
customerReference = "wwww"
customer = {array} [2]
 0 = {array} [1]
  name = "wwww"
 1 = {array} [1]
  name = ""
submit = ""

我理解这是ManyToMany的例子。我的问题是如何创建新发票的表单和按钮，以便在需要时添加新客户

现在我的表单（需要添加来自DB的客户以及下拉列表）

        $builder
        ->add('companyReference')
        ->add('customerReference')

        ->add('customer', CollectionType::class, array(
            'entry_type' => CustomerForm::class,
            'allow_add'    => true,
        ))

        ->add('customers', 'entity', array(
            'class' => Customer::class,
            'attr' => array('class' => 'form-control select2 all_customers'),
            'property' => 'name',
            'empty_value' => 'Choice Customer',
            'query_builder' => function ($repository) {
                /** @var CustomerRepository  $repository */
                return $repository->getAllQuery();
            },
            'required' => false,
            'mapped' => false,
            )
        );

CustomerForm

    class CustomerForm extends AbstractType
   {
        $builder
        ->add('name');

    $('.all_customers').on('change', function () {
