如何包含票证属性

编辑

我决定把票忘了，只延长行项目。但还是有同样的问题。我已尝试将：开始日期属性添加到

order\u参数

，如下所示（b/c开始日期是一个

date\u选择

：

def order_params
      if params[:order]
        params[:order].permit(*permitted_order_attributes, :"start_date(1i)")
      else
        {}
      end
    end

这是：

def order_params
      if params[:order]
        params[:order].permit(*permitted_order_attributes, :start_date)
      else
        {}
      end
    end

在

Spree:：OrdersController#update

中，您试图

更新

属性

票据

，这是不允许的。

因此，在OrdersController中允许

票证作为强参数（order\u params方法）对于您的<代码>命令> />代码> ./p> ，可以直接将属性添加到核心/LIB／SPRE／Cyr/控件/Helps/StrugIsPosits中的强参数。参数：您的_属性

@科蒂·索拉特：谢谢你的回答。我之所以不接受你的回答，仅仅是因为我已经按照问题的解决方法去做了，而改变方法并没有达到预期的效果
这是我必须做的
def permitted_order_attributes
  permitted_checkout_attributes + [
    :line_items_attributes => permitted_line_item_attributes, 
    :start_date => :start_date
  ]
end

我不确定您是否收到了编辑通知。因此，我在这里评论b/c我相信您会收到通知。再次感谢。@user2168130更新订单@order.update\u属性（订单参数）
在您的update
操作中被调用，其中在order\u params
方法中，将指定order
模型允许并允许更新的所有属性。您需要在order\u params
方法中指定ticket
属性，否则它将不会被更新。是的，我知道是什么你在说，但我不明白“如何”。此外，我改变了我的方法b/c，我无法理解。我决定扩展行项目本身。但是，我仍然需要将属性添加到order参数。我只是不知道如何。这是因为在@order.update\u attributes（order\params）中调用的方法
。请注意，order\u params
作为参数传递给update\u attributes调用。方法名称order\u params
无关紧要，您可以使用相同的许可代码调用名为xyz
的方法，并将其称为@order.update\u attributes（xyz）它仍然可以工作。好的。那么，我该怎么做呢？你修改了核心库吗？或者你扩展了核心库还是破坏了核心库？文件放在哪里？看看这个，我相信我是根据我回答的措辞将其添加到Spree的核心库文件中的。
