Question

我在使用Rails构建的事件应用中遇到上述错误。该错误与bookings_controller中的“show”操作有关，如此处所阐明的那样 -

'没有路由匹配{：action =＆gt;“show”，：controller =＆gt;“bookings”' - 错误消息。

预订系统旨在满足免费和付费预订。免费预订路线会根据需要转到展会页面。进行付费预订时会发生上述错误（通过Stripe付款）。这是相关的控制器代码 -

bookings_controller.rb

 def new
    @event = Event.find(params[:event_id])
    @booking = @event.bookings.new(quantity: params[:quantity])
    # which person is booking the event?
    @booking.user = current_user



end

def create

    @event = Event.find(params[:event_id])
    @booking = @event.bookings.new(booking_params)
    @booking.user = current_user

        if 
            @booking.paid_booking
            flash[:success] = "Your place on our event has been booked"
            @booking.update_attributes!(booking_number: "MAMA" + '- ' + SecureRandom.hex(4).upcase)
            redirect_to event_booking_path(@event)
        else
            flash[:error] = "Booking unsuccessful"
            render "new"
        end
end

def free_booking
        if 
            @booking.free_booking
            @booking.update_attributes!(booking_number: "MAMA" + '- ' + SecureRandom.hex(4).upcase)
            redirect_to event_booking_path(@event)
        else
            flash[:error] = "Booking unsuccessful"
            render "new"
        end
end

def show
    @event = Event.find(params[:event_id])
    @booking = @event.bookings.new
    @booking = Booking.find_by(params[:booking_number])
end

def update
    puts params
    @event = Event.find(params[:event_id])
    @booking = @event.bookings.new(booking_params)


    if @booking.save
        redirect_to event_booking_path , notice: "Booking was successfully updated!"
    else
        render 'new'
    end
end




private

def booking_params
    params.require(:booking).permit(:stripe_token, :booking_number, :quantity, :event_id, :stripe_charge_id, :total_amount)
end

错误消息重点关注@ booking.paid_booking方法中的这一行 -

  redirect_to event_booking_path(@event)

这是奇怪的，因为它与free_booking使用相同的路由，路由到显示页面没有错误。

这是我的免费观看形式付费预订 -

     <% if @booking.free_booking %>

这是路线档案 -

的routes.rb

     Rails.application.routes.draw do



  devise_for :users, :controllers => { omniauth_callbacks: "omniauth_callbacks", registrations: "registrations" }  


  resources :users
  # the above resource draws out routes for user profiles
  resources :events do

    resources :comments
    resources :bookings
  end





    root 'events#index'



end

路线 -

我确信这是非常明显的事情，我担心我无法发现它。

Answer 1

你有嵌套资源和助手应该用两个参数调用。第一个是：event_id，第二个是：id。：id可能是书ID

这样的事情：

 redirect_to event_booking_path(EVENT_ID, ID)

Answer 2

所以，提供的答案之一 - 虽然它实际上没有工作 - 让我想到了参数，并且需要两个 - @event＆amp; @booking。这就是我所做的修复 -

if 
            @booking.paid_booking
            flash[:success] = "Your place on our event has been booked"
            @booking.update_attributes!(booking_number: "MAMA" + '- ' + SecureRandom.hex(4).upcase)
            redirect_to event_booking_path(@event, @booking)
        else
            flash[:error] = "Booking unsuccessful"
            render "new"
        end
end

def free_booking
        if 
            @booking.free_booking
            @booking.update_attributes!(booking_number: "MAMA" + '- ' + SecureRandom.hex(4).upcase)
            redirect_to event_booking_path(@event, @booking)
        else
            flash[:error] = "Booking unsuccessful"
            render "new"
        end

Rails错误 - BookingsController中的ActionController :: UrlGenerationError #create
