获取语​​法错误，意外的输入结束

Question

我不断收到语法错误，意外的输入结束，尽管检查了代码，甚至在删除代码并运行它之后，问题似乎无法解决。代码是：

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

Answer 1

您错过了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

Answer 2

Bogus update方法;您错过了end支票的current_user。

同样重定向不停止执行代码，您需要返回。

Answer 3

实际错误 - end条件后错过unless。

您甚至可以像这样重构代码

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