Simple_Fields_For不保存子记录的数据

Question

我目前正在尝试修复delivery，delivery_orders和订单模型之间的关系。我一直在努力保存一个嵌套表单，该表单存储delivery_orders表中的订单。基本上，我希望能够创建交货，然后通过delivery_order模型向交货添加订单。普通用户创建订单，但经理处理这些订单的交货。到目前为止，我一直无法为delivery_order模型保存嵌套的simple_form_for部分。即使关系设置为支持事务，它也会继续返回nil。一方面注意，我无法通过交付模型读取订单的属性。我写的代码如下。结构用户 - ＆gt;订单 - ＆gt;经理交货[Delivery_order] - ＆gt;卡车[交货]
