我正在尝试将图像合并到我的网络应用程序中,并在删除了一些功能后继续遇到此错误.它归结为我的"创建"应用程序控制器,我不完全确定我应该从哪里开始.

Articles_controller.rb

class ArticlesController < ApplicationController
http_basic_authenticate_with name: "name", password: "password", except: [:index, :show]

    def index
        @articles = Article.all.order("created_at DESC")
    end

    def show
        @article = Article.find(params[:id])
    end

    def new
        @article = Article.new
    end 

    def edit
        @article = Article.find(params[:id])

    end …

我正在研究一些应用学院的练习题,我似乎无法打印两个00的时间转换.这是我到目前为止所拥有的:

def time_conversion(minutes)
  hours = minutes/60            
  if minutes%60 < 10
    minutes = minutes%60
  elsif minutes%60 > 10
    minutes = minutes%60
  elsif minutes%60 == 0
    minutes = 00
  end        

  return "#{hours}:#{minutes}"
end

time_conversion(360)
