Symfony 2将数据持久化到具有关系的一个表

标签： php symfony doctrine-orm symfony-forms

我在提交包含有效数据的表单后尝试在数据库中保存记录，但我收到了下一个错误：

  

关联字段“AppBundle \ Entity \ Usuario＃$ gender”类型“AppBundle \ Entity \ Gender”的预期值，取而代之的是“string”。

我想在Usuario表中保存一条记录，但我不明白为什么它不能像这样工作。

我的实体是：

答案 0 :(得分：2)

UsuarioSignUpType类的代码是什么。您是否定义了性别字段以使用您的性别实体？

如果不是，你应该做这样的事情

$builder->add(
  'gender',
  'entity',
  array(
  'class' => 'AppBundle:Gender',
  'property' => 'name',
  'empty_value' => 'Choose your gender'
  )
