Question

我是新手，我用Google搜索了这个问题，没有任何帮助。有人可以向我解释错误是什么吗？我已经尝试过git add，然后提交再次推送到heroku那些东西。

O.k。弄清楚了。你的pins_controller.rb中的“结束”搞砸了。如果你删除第52行的结尾（是最后一个）和第40行它应该工作，它为我做了我现在正在看你的应用程序。

只是你知道我通过使用

弄明白了

 heroku run rails c

有时会为您提供更多有用的信息，在这种情况下，它指向您的控制器并告诉我有关语法错误。

如果您想要复制并粘贴此代码应该在下面工作，它适用于我，请不要忘记点击复选标记，如果这解决了您的问题。

class PinsController < ApplicationController
   before_action :set_pin, only: [:show, :edit, :update, :destroy]

   def index
     @pins = Pin.all
    end

   def show
   end

   def new
    @pin = Pin.new
   end

   def edit
   end

  def create
    @pin = Pin.new(pin_params)

    if @pin.save
      redirect_to @pin, notice: 'Pin was successfully created.' 
     else
    render :new 
  end
end

 def update
     if @pin.update(pin_params)
       redirect_to @pin, notice: 'Pin was successfully updated.'
     else
      render :edit 
    end
  end
end

 def destroy
   @pin.destroy
    redirect_to pins_url
 end

  private
     #Use callbacks to share common setup or constraints between actions.
  def set_pin
    @pin = Pin.find(params[:id])
   end

   # Never trust parameters from the scary internet, only allow the white list through.
   def pin_params
     params.require(:pin).permit(:description)
   end

推送到Heroku后的应用程序错误
