Ruby on rails 在rails中的嵌套属性中键入什么？

我的问题是，在完成删除、创建和更新操作后，如何重定向到事件显示页面

我是rails的新手，所以请帮助我。我有这样的路由文件

resources :occasions do
    resources :events
  end

  resources :events do
    resources :event_details
  end

我的事件详细控制器是：

before_action :set_event
  before_action :set_event_detail, except: [:new, :create]

  def new
    @event_detail = EventDetail.new
  end

  def create
    @event_detail = EventDetail.new(event_detail_params)
    @event_detail.event = @event

    @event_detail.save
    redirect_to
  end

  def edit

  end

  def update
    @event_detail.update(event_detail_params)
  end

  def destroy
    @event_detail.destroy
    redirect_to ??
  end


  private

  def set_event
    @event = Event.find(params[:event_id])
  end

  def set_event_detail
    @event_detail = EventDetail.find(params[:id])
  end

  def event_detail_params
    params.require(:event_detail).permit(:capacity, :start_time, :end_time)
  end

现在，我所知道的是，路线上显示了很多事件，事件有很多事件细节。但是，在我的控制器中，我没有机会，所以在删除或更新我的事件详细信息后，我无法路由到页面

我的rake路由文件

  rake routes

我可以创建事件详细信息，但我必须刷新页面并手动转到以查看新创建的内容。在创建事件详细信息后，是否有任何方法可以重定向回此“”页面。任何帮助都将不胜感激

我得到的错误是：

---

删除：索引和：显示，路由定义中除外，然后在创建/更新后，尝试：

redirect_to event_event_detail_path(@event_detail)

销毁后，将不会有@event\u详细信息可重定向到，因此您可能希望：

redirect_to event_details_path

也

。。。将向您展示您的申请路线，并为这些黑暗时刻带来光明

---

redirect\u to

采用路径参数，例如

events\u path

重新记录到events索引操作，或'event\u event\u detail\u path（@event\u detail）重新定向到@event\u detail show操作。您可以使用redirect_通知客户端（浏览器）转到路由中列出的应用程序的任何部分，甚至是相对或绝对URL。稍后，您将了解到您还可以添加各种参数和HTTP状态代码。

首先，您需要更改路由

resources :occasions do
    resources :events do
      resources :event_details
    end
end

然后，您可以发布您的rake路由，并根据事件索引或事件索引的路由进行路由。

您可以这样做

redirect_to event_path(@event)

---

我输入代码后出现的错误是#的未定义方法'event_detail_path'。您的意思是？event_detail_params def create@event_detail=EventDetail.new（event_detail_params）@event_detail.event=@event@event_detail.save重定向_到event_detail_路径（@event_detail）endRight，它的名称空间。。。从路由定义中删除：show，然后再次运行rake路由，它将向您显示路径。rails路由指南也将帮助您了解许多事情，并为您提供一个新的角度来规划应用程序结构。谢谢傅，非常感谢，先生，在发布之前必须开始考虑我的评论！在遵循了你提到的所有建议之后，我仍然会遇到同样的错误。谢谢。但是rails文档说不要深入嵌套多个资源。这是一个好的选择吗？Akhil是对的，它可以工作！继续这样做，然后再次运行

rake routes

，看看它是什么样子。Pandey ji，如果要去参加活动，我需要一个场合id。因此，正如我提到的，我的资源不包括场合。所以重定向到事件路径首先搜索事件id，然后搜索我当前路由中没有的事件id。Jay Nepal.

event GET/events/：id（：format）

我怀疑您是否需要场合id？你想去哪里？在偶发事件中？我所拥有的是偶发事件有很多。事件有很多场合。所以，在《盛会》的节目页面上，有一些活动的列表。现在，在每个事件的显示页面下都有许多事件详细信息（时间段等）。现在，在我创建了一个event_details之后，我想转到event_show页面，它嵌套在一个场合中。因此，将事件重定向到事件路径（@event）将尝试查找时机，这在事件详细信息控制器中不可用。Hajur le malai导师garney ho bhane ma paisa Tirra padhna tayar chu.当然，我可以根据您所指的指导您的路线应该是

资源：场合做资源：事件做资源：事件细节结束

我需要查看视图，但我需要参考所有代码来解决这个问题，您能给出代码吗这是我的电子邮件ynique。adhar@gmail.com
