ruby-on-rails - 如何将rails更改为开发模式

Question

在 rails (3.2.3) 的文档中说

In development mode (which is what you’re working in by default), Rails reloads your application with every browser request, so there’s no need to stop and restart the web server.

但显然我的应用程序在开箱即用的生产模式下加载。(我可以键入 Rails.env 并查看它)。

为什么？

然后我转到 environment.rb 并添加

ENV["RAILS_ENV"] = "development"

它仍在生产中。任何的想法？

编辑:给你

#Load the rails application
require File.expand_path('../application', __FILE__)

# Initialize the rails application
MyAppName::Application.initialize!

ENV["RAILS_ENV"] = "development"

Answer 1

针对您的情况可能的解决方案是:

rails server -e development
