ruby-on-rails - 在rails的嵌套属性中输入redirect_to的内容是什么？
问题描述
我的问题是如何在删除、创建、更新操作完成后重定向到事件显示页面。
我是 Rails 的新手，所以请帮助我。我有这样的路线文件。
resources :occasions do
resources :events
end
resources :events do
resources :event_details
end
我的 event_detail 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，我所拥有的是 Occasion 有许多事件，如路线所示，事件有许多 event_details。但是，在我的控制器中我没有机会，所以在我删除或更新我的 event_detail 后，我无法路由到http://localhost:3000/occasions/1/events/1页面。
我的 rake 路线文件

我的事件控制器
# before_action :authenticate_user!
before_action :set_occasion, expect: [:index, :show]
before_action :set_event, except: [:new, :create]
# after_action :verify_authorized
def new
@event = Event.new
# authorize @event
end
def create
@event = Event.new(event_params)
@event.occasion = @occasion
# authorize @event
@event.save
redirect_to occasion_path(@occasion)
end
def edit
# authorize @event
end
def show
# authorize @event
end
def update
# authorize @event
@event.update(event_params)
redirect_to occasion_path(@occasion)
end
def destroy
# authorize @event
@event.destroy
redirect_to occasion_path(@occasion)
end
private
def set_event
@event = Event.find(params[:id])
end
def set_occasion
@occasion = Occasion.find(params[:occasion_id])
end
def event_params
params.require(:event).permit(:name, :location, :description, :isMakeAhead)
end
end
还有我在 event#show 页面中的视图文件：
<h1>Event Info</h1>
<table>
<thead>
<tr>
<td>Name</td>
<td>Location</td>
<td>Description</td>
<td>Make ahead</td>
<td>Capacity</td>
</tr>
</thead>
<tbody>
<tr>
<td><%= @event.name %></td>
<td><%= @event.location %></td>
<td><%= @event.description %></td>
<td><%= @event.isMakeAhead %></td>
</tr>
</tbody>
</table>
<%= render @event.event_details %>
<p><%= link_to "Create Time slots", new_event_event_detail_path(@event,@event_detail) %></p>
我可以创建一个 event_detail 但我必须刷新页面并手动转到http://localhost:3000/occasions/1/events/1以查看新创建。在创建 event_detail 后有什么办法，我可以重定向回这个“ http://localhost:3000/occasions/1/events/1 ”页面。任何帮助将不胜感激。
我得到的错误： 在此处输入图像描述
解决方案
首先，您需要更改路线。
resources :occasions do
resources :events do
resources :event_details
end
end
然后，您可以发布您的 rake 路线，并根据场合索引或事件索引的路线进行路线。
