Question

当我将rails应用程序（使用restful_authentication）部署到Heroku时，我收到以下错误：

/usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:105:in `const_missing': uninitialized constant User::Authentication (NameError)

 from /home/heroku_rack/heroku.ru:1:in `new'

我怎样才能让它发挥作用？

Answer 1

你在Heroku上安装了gem“restful_authentication”吗？错误消息表明它不存在。

Answer 2

我在这里摸索，特别是因为你没有提出完整的追溯。

但是，可能与cache_template_extensions有关。

http://www.mail-archive.com/heroku@googlegroups.com/msg02172.html就您的问题进行了讨论，http://forums.pragprog.com/forums/66/topics/2484在升级到2.3.2时提到了这个问题。

底线：在代码（development.rb或其附近的某个地方）找到引用cache_template_extensions的行，然后将其删除。

祝你好运。

谢谢大家！看起来这是Heroku结束时遇到的问题。我联系了他们的支持，他们必须做点什么。

现在有效。：）
