如何在应用程序中扩展Rails可安装引擎资产？

Question

Imagine we have Rails Engine blog . 想象一下，我们有Rails Engine blog 。

The engine's structure is: 引擎的结构为：

blog
    assets
    javascripts
        blog
            master.js
            application.js
    controllers
        ...
    helpers
        ...

application.js is application.js是

//= require_tree .

master.js holds some JavaScript code. master.js包含一些JavaScript代码。

Also I have my application using this engine at /blog . 我的应用程序也在/blog使用此引擎。

My question is: How can I add some JavaScript code to engine from my application? 我的问题是：如何从应用程序向引擎添加一些JavaScript代码？

Answer 1

Solution is: 解决方法是：

Ensure bundle files (application.js, application.css) on plugin and application have different names. 确保插件和应用程序上的捆绑文件（application.js，application.css）具有不同的名称。 In my example plugin's bundle will be bundle.js, and application's bundle — application.js 在我的示例中，插件的包将是bundle.js，应用程序的包将是application.js
bundle.js will look like: bundle.js看起来像：
require_tree . require_tree。
application.js will look like: application.js将如下所示：
require blog/bundle 需要博客/捆绑
require_tree . require_tree。

The problem was in name overlapping - application's bundle was overlapping engines one. 问题在于名称重叠-应用程序的捆绑软件是重叠的引擎。
