Question

错误：没有路线匹配[GET]＆＃34; /预订/：id /％3E：格式＆＃34;

我想点击链接＆＃39; link_to＆＃39; ..

时更新属性

<%= link_to 'Cancel', '/bookings/:id/(.:format)' %>

的routes.rb

put '/bookings/:id/(.:format)' => "bookings#tocancel"
patch '/bookings/:id/(.:format)' => "bookings#tocancel"

控制器

def tocancel
 @booking = Booking.find(params[:id])
 @booking.update_attribute(:status, "cancel")
 respond_to do |format|
  format.html { redirect_to @booking, notice: 'Booking was successfully cancelled.' }
  format.json { render :show, status: :ok, location: @booking }

端

Answer 1

在预订控制器中创建一个方法：

def tocancel
 @booking = Booking.find(params[:id])
 @booking.update_attribute(:status, "cancel")
 respond_to do |format|
  format.html { redirect_to @booking, notice: 'Booking was successfully cancelled.' }
  format.json { render :show, status: :ok, location: @booking }
 end
end

这方面的路线是：

resources :bookings do
  member do
   get :tocancel
  end
end

取消链接可以创建为：

link_to "Cancel", tocancel_booking_path(booking.id)

在这里你应该将booking_id传递给取消链接。现在检查你在这个取消链接的页面上如何获得booking_id。如果有任何问题，请告诉我。

Rails：尝试通过link_to更新属性时发生路由错误
