将多个参数传递到路由帮助程序链接中

问：

我是 Rails 的新手。我正在尝试建立一个网站。以下是我的数据模型：

- user: 
has_many :created_events, foreign_key: "creator_id", class_name: "Event"
has_many :guest_events, foreign_key: "attendee_id"
has_many :attended_events, through: :guest_events

- event: 
belongs_to :creator, class_name: 'User'
has_many :event_guests, foreign_key: "attended_event_id"
has_many :attendee, through: :event_guests

- event_guest: 
belongs_to :attendee, class_name: "User"
belongs_to :attended_event, class_name: "Event

我希望我的用户能够参加一个活动，所以我在 .如果他们已登录并参加该活动，则可以通过单击视图中的其他帮助者来选择不再参加该活动。link_touser/show.html.erblink_to

我的问题是当用户单击“不参加”链接时，我遇到以下错误：

No route matches [GET] "/events/7/event_guests.4"   

• config/routes.rb文件：

   resources :events do 
     resources :event_guests, only: [:create, :destroy]
   end
   resource :user do 
     resources :events 
   end
  

• Event_guests路线：

    Prefix Verb                URI Pattern                         Controller#Action
    event_event_guests POST   /events/:event_id/event_guests(.:format)     event_guests#create
    event_event_guest DELETE /events/:event_id/event_guests/:id(.:format) event_guests#destroy
  

• EventsController:

   def show 
     @event = Event.find(params[:id])
     @event_guest = EventGuest.where("attended_event_id = ? AND attendee_id = ?", @event.id, current_user.id)
     if @event_guest.exists? 
       @event_guest = @event_guest.take 
     else 
       @event_guest = nil 
     end
   end 
  

• EventGuestsController:

   def destroy 
     if EventGuest.exist?(params[:id])
       @event_guest = EventGuest.find(params[:id])
       @event_guest.destroy 
     end
     redirect_to root, status: :see_other
   end 
  

• link_to以下助手：user/show.html.erb

   <%= link_to "Attend", event_event_guests_path(@event), data: { turbo_method: "post" } %>
   <% if user_signed_in? &&  !@event_guest.nil? %>
     <%= link_to "Not attend", event_event_guests_path(@event, @event_guest), data: {turbo_method: "delete" } %>
   <% end %>
  

在助手中，我尝试了：link_to "Not attend"

• event_event_guests_path(@event.id, @event_guest.id)

• event_event_guests_path(@event, :id => @event_guest.id)

• event_event_guests_path(:event_id => @event.id, :id => @event_guest.id)

但他们都没有奏效。我曾经对用户进行身份验证。 请帮帮我！谢谢。devise
