Rails：尝试通过link_to更新属性时出现路由错误

Question

错误：没有路线匹配 [GET] "/bookings/:id/%3E:format"

我想在单击“link_to”链接时更新属性..

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

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 }

结束

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

为此的路线将是：

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，您应该将 booking_id 传递给取消链接。现在检查您如何在放置此取消链接的页面上获得 booking_id。 如果有任何问题，请告诉我。
