ruby-on-rails - 获取语​​法错误，输入意外终止

Question

尽管检查了代码，但我仍然收到语法错误，意外的输入终止，甚至在删除代码并运行它之后，问题似乎也没有解决。以下是代码:

class BookingsController < ApplicationController

before_filter :authenticate_user!

def new
    @booking = Booking.new
end

def create
    @booking = current_user.booking.create(booking_params)
    if @booking.save
        flash[:alert] = "You have now booked a date"
        redirect_to root_path
    else
        flash[:alert] = "Error:booking did not save"
        redirect_to root_path
        render 'new'
    end
end


def show
    @booking = Booking.find(params[:id])
end

def edit
    @booking = Booking.find(params[:id])

    unless @booking.user == current_user
        redirect_to root_path
    end
end

def update 
    @booking = Booking.find(params[:id])
    unless @booking.user == current_user
        redirect_to root_path

    if @booking.update_attributes(booking_params)   
        redirect_to root_path
        flash[:notice] = "You have edited your post"
    else
        render 'edit'
        flash[:alert] = "something went wrong"
    end
end

def destroy 
    @booking = Booking.find(params[:id])
    @booking.destroy
    redirect_to root_path
end 

private
def booking_params
    params.require(:booking).permit(:content)
end

end

您在这里错过了end关键字

def update 
    @booking = Booking.find(params[:id])
    unless @booking.user == current_user
        redirect_to root_path
    end # <~~~ missed in your code
    if @booking.update_attributes(booking_params)   
        redirect_to root_path
        flash[:notice] = "You have edited your post"
    else
        render 'edit'
        flash[:alert] = "something went wrong"
    end
end
