ruby-on-rails – 部署到Heroku时的不同页面外观

概述我尝试使用一些 Kendo UI小部件,它们在开发中运行良好.但是当我将我的应用程序部署到Heroku时,它的外观发生了巨大变化. 我用TreeView小部件编写了一个示例页面.这就是它在开发中的呈现方式： 在Heroku的制作中： 可以看出,缺少列表标记(树标记？). 我怀疑这个问题与资产管道有关,因为做rake资产：预编译也会破坏开发中的东西(以及rake资产：清理还原它).但这让我感到困惑, 我尝试使用一些 Kendo UI小部件,它们在开发中运行良好.但是当我将我的应用程序部署到Heroku时,它的外观发生了巨大变化.

我用TreeVIEw小部件编写了一个示例页面.这就是它在开发中的呈现方式：

在Heroku的制作中：

可以看出,缺少列表标记(树标记？).

我怀疑这个问题与资产管道有关,因为做rake资产：预编译也会破坏开发中的东西(以及rake资产：清理还原它).但这让我感到困惑,因为我的Bootstrap标题在开发和生产中都运行良好(尽管在Heroku日志中有一些ActionController :: RoutingError(没有路由匹配[GET]“/assets/bootstrap/loading.gif”)错误).

的Gemfile：

在我的清单CSS文件(application.CSS)中包含两个与Kendo相关的CSS文件：kendo.common.min.CSS(包含公共代码,unminified version)和kendo.bootstrap.min.CSS(主题特定代码,unminified version) .

顺便说一句,kendoui-rails gem中的供应商目录具有以下结构：

vendor└── assets    ├── JavaScripts    │   └── ...    └── stylesheets        └── kendo            ├── bootstrap            │   ├── editor.png            │   ├── imagebrowser.png            │   ├── loading.gif            │   ├── loading-image.gif            │   ├── slIDer-h.gif            │   ├── slIDer-v.gif            │   └── sprite.png            ├── ... # Some other theme-specific dirs            ├── kendo.bootstrap.min.CSS            ├── kendo.common.min.CSS            └── ... # Some other theme-specific CSS's

文件kendo.bootstrap.min.CSS包含引用图像(url(‘bootstrap / sprite.png’)和url(‘bootstrap / loading.gif’))的代码,这些代码未在生产中显示(但它们存在于bootstrap目录),所以我认为Chris Rueber是正确的.那我怎么解决这个问题呢？

解决方法 将bootstrap文件夹移动到vendor / assets / images(如果它不存在,则创建它).查看 http://guides.rubyonrails.org/asset_pipeline.html#css-and-sass获取更多信息. 总结
