Question

在具有集合字段的表单中，集合中包含实体字段（成员类型中的eid），添加集合验证会导致实体字段抛出以下错误：

在渲染模板期间抛出了异常（“注意：Mana \ ClientBundle \ Entity \ Ethnicity类的对象不能转换为int

未经验证，实体字段处理得当。将实体字段添加到验证器无效。

->add('members', 'collection', array(
    'type' => new MemberType(),
    'allow_add' => true,
    'allow_delete' => true,
    'by_reference' => false,
    'prototype' => true,
))

会员类型：

->add('include', 'choice', array(
    'choices' => array('Yes' => 'Yes', 'No' => 'No'),
    'empty_value' => false,

Answer 1

您的会员实体是否与您的种族实体有关系？从名称“eid”来看，您似乎试图将种族类强制为整数字段（“eid”）。

如果没有看到这两个实体，很难找到任何东西。

Answer 2

原来我的错误是假设集合字段需要集合验证器。相反，验证器只需要在构成集合的实体上。在这种情况下，我真正需要做的就是在Member实体中指定验证（并删除客户端实体中的注释断言。）当我简化了种族实体字段时，处理得当。所以我的错误还包括Symfony更复杂的概念 - 并非总是如此，有时候也是如此！
