Question

当我在生产模式下向ActiveRecord模型添加新项目时，我的rails网站会抛出500错误。在开发模式下，它会抛出404.在生产和开发中，简单刷新页面可以解决问题。

这是日志。

我对正在发生的事情的最好猜测是模型花了很长时间才更新，并且页面试图在尝试保存模型的同时从模型中提取信息，因此它返回Nil值并且页面崩溃。但是，我可能完全错了。谁能指出我在这里的正确轨道。 Rails试图做什么，以及我如何阻碍它？

这是我的控制器：

def edit
    @question = Question.find(params[:id])
end 

def update
    @question = Question.find(params[:id])
    if @question.save 
        redirect_to '/'
    else
        redirect_to '/error/could_not_save'
    end 
end 

def index 
    @questions = Question.all 
    respond_to do |format|
        format.js
        format.html
    end 
end 

def new 
    @question = Question.new 
end 

def create 
    @question = Question.new(question_params)
    if @question.save
        redirect_to '/' 
    else 
        redirect_to '/error/could_not_save'
    end 
end 

def destroy
    Question.find(params[:id]).destroy
    redirect_to '/index'
end 

private
    def question_params
        params.require(:question).permit(:topic, :prompt, :correct_answer, :wrong_answer_one, :wrong_answer_two, :wrong_answer_three)
    end

这是config / routes：

Rails.application.routes.draw do

  resources :questions

  root 'static#home'

  get '/home' => 'static#home'
  get '/error/unknown_error' => 'static#unkown_error'
  get '/error/could_not_save' => 'static#could_not_save'

  get '/:id/edit' => 'questions#edit', as: @question
  post '/index' => 'questions#update'
  get '/home' => 'questions#home'
  get '/new' => 'questions#new'
  get '/questions' => 'questions#index'
  get '/question' => 'question#index'
  post '/index/' => 'questions#create'
  get '/index' => 'questions#index'
  get '/practice' => 'questions#practice'
end

ActiveRecord 500错误，但修复后修复
