我已经查看了整个互联网,试图找出为什么这个错误发生在我身上。我正在尝试使用 Rails 3.2.7 中的回形针 gem 上传文件并给我这个错误:
NoMethodError in ItemsController#create
undefined method `match' for nil:NilClass
Rails.root: C:/Users/AC_37-PC_BH/RubymineProjects/railstutorial-sample_app_2nd_ed-815d98a

我在项目中包含了一个 github,所以你们可以测试它。并尝试看看出了什么问题。您必须手动访问 localhost:3000/items/new 才能看到该页面
