我需要使用对使用 Rails 创建的新应用程序的访问权限从旧应用程序推送一些数据。我已将 Access 数据导出到 .xls 并使用 gem 访问它roo。

它工作得很好，我创建了一个脚本并通过打印结果我确信它一切正常，现在我想让它自动将这些数据插入数据库中，访问 Rails 应用程序模型。

我尝试将文件放在我的 railslib/目录下，然后我需要它environments/development.rb，但是当我导入 ruby​​ 文件时，它声称找不到一些我需要进行处理的变量。

为了完整起见，这是我开发的用于从 xls 中提取数据并对其进行编辑以匹配新的 db 模式的整个源代码。

hostess_id_conversion = {139 => 9, 157 => 17, 153 => 18, 110 => 20, 40 => 19, 141 => 21, 121 => 22, 151 => 23}
status_conversion = {1 => "Inserito", 2 => "Rifiutato", 3 => "Visitato", 4 => "Inserito", 5 => "Ricontattare", 6 => "Vendita"}

如何在 rails 环境中进行这项工作？我正在考虑制作一个在控制台中运行的类或函数之类的东西，rails c因为我今晚需要运行以获得最新的数据库版本，提取带有更新记录的 xls 并施展魔法。

抱歉，这似乎是一个菜鸟问题，但我是 Ruby 新手。

PS 我正在使用带有 Ruby 1.9.3 PPS 的 Rails 3.2.3 我在 Gemfile 中插入了“roo”，因为它首先没有找到 gem。

谢谢。

如果你这样做

rails runner path/to/script

然后rails会加载rails环境，然后运行你的脚本
