无法使 Rails 3.1.1 资产管道在 Heroku Cedar 部署上工作

Question

我已关注Rails 3.1 on Heroku Cedar 教程以及另外六篇文章，但无法使其正常工作。

在推送 Heroku 后，该应用程序没有任何可用的 CSS/js。

Push 编译和注入 rails3_serve_static_assets 似乎没有任何错误：

有什么帮助吗？

更新：

在 heroku 日志中，我注意到两件事：

1. 可能没关系，我不知道，...但它似乎在寻找标准的 public/javascripts 路径：

   heroku[路由器]：获取 gitwatcher.com/javascripts/application.js

2. 比，似乎缺少缓存：

   缓存：[GET /] 未命中

...这里是一些日志：

@RyanWilcox： ...无论如何我确认这是一个雪松堆栈：

lsoave@ubuntu:~/rails/github/gitwatcher$ heroku info --log | grep -i stack
Stack:          cedar
lsoave@ubuntu:~/rails/github/gitwatcher$

Answer 1

你确定确定你在雪松上吗？你检查过heroku stack 吗？

例如，在我以前的应用程序中，我确定我使用的是 cedar。 Heroku: Cedar and the asset pipeline 的文章谈到了 git push heroku ... 的回话：

准备 Rails 资产管道`

但我没有在我的应用程序中看到这一点。然后我检查了一下，我在 Bamboo...

Answer 2

使用 mongoid 我必须从 config/application.rb 中删除 require 'rails/all'，

这就是我没有看到 heroku 日志记录的方式：

-----> Preparing app for Rails asset pipeline

因为没有加载链轮。

如果您使用MongoID configuration，则必须将以下行添加到 config/application.rb ：

需要“sprockets/railtie”
