在 Rails 3 中渲染 Markdown 文本
我想将 markdown 转换为 html。在我看来，我有 markdown(some_text_variable) 但收到错误 undefined method markdown。
我向 enviroment.rb 添加了 require 'BlueCoth' 并安装了 BlueCloth gem。有人可以帮助我吗？

#markdown帮助器已在 Rails 3 中删除。您可以复制并粘贴提交中的代码或使用第三方 Gem，例如 formatize。您还必须在
Gemfile中包含所需的BlueCloth/RedCloth/etc gem。The
#markdownhelper was removed in Rails 3.You can copy & paste the code from the commit or use a third party Gem, like formatize. You will also have to include the required
BlueCloth/RedCloth/etc gem in yourGemfile.尝试将以下内容添加到您的
environment.rb中，而不是 require：在 Rails 3 中，这将位于 Gemfile 中：
该 gem 称为 BlueCloth，但所需的 .rb 文件全部为小写。

environment.rbinstead of the require:In Rails 3, this would be in the Gemfile:
The gem is called BlueCloth, but the .rb file that gets required is all lowercase.
Make sure you restart rails after adding the config.gem line.
