我有一个包含多个表的数据库。其中一个用作静态信息源以输入其他表格。我创建了一个表格，第一个表格被循环使用并用于构建输入字段。这些字段有一个复选框，理想情况下，如果复选框被选中，它会在提交后将该字段保存到第二个表中。动态生成的字段没有保存
但是，它根本不会保存到第二个表中，而其余的 表单（嵌套表单）的确如此。
这是怎么回事？我在服务器日志中没有任何错误。
_form的一部分。总共包含6个这样的块和2个其他块。其他块没有正确保存：
<div class="card">

的创建功能
def create

@enquiry = Enquiry.new(enquiry_params)
#@enquiry.enquirymeasures.build
