Rails - Rails.root.join 部署后行为异常 [英] Rails - Rails.root.join misbehaving after deployment

问题描述

我的 app/assets 目录中有 javascripts 和 stylesheets 目录，就像任何普通的 Rails 应用程序一样.

I have, in my app/assets directory, the directories javascripts and stylesheets, as any normal Rails app.

不过，我也想有一个插件目录.

I wanted, however, to have a plugins directory as well.

示例:

app/assets/plugins/myPlugin1/somefile.js
app/assets/plugins/myPlugin1/somefile.css

事情是，如果我使用

<%= javascript_include_tag 'plugins/myPlugin1/somefile.js' %>

我会收到 404 错误，因为

I would get a 404 error, as

/assets/javascripts/plugins/myPlugin1/somefile.js

不存在.然后，我注意到插件"目录正试图在 javascripts 中访问.我认为这与javascript_include_tag"有关.

does not exist. I noticed, then, that "plugins" dir was trying to be accessed inside javascripts. I assume this have something to do with "javascript_include_tag".

经过一番研究，我意识到我必须将此行包含在 config/application.rb 中

After some research, I realized I had to include this line into config/application.rb

config.assets.paths << Rails.root.join("app", "assets")

它似乎奏效了.在 WEBRick 和开发方面，它运行良好.

And it seemed to work. On WEBRick, on development, it worked beautifully.

现在我成功部署到服务器，预编译资产，并认为我已经准备好了.

Now I deployed successfully to a server, precompiled the assets, and thought I was ready to go.

目录

/public/assets/

已创建.app/assets/javascripts"、app/assets/stylesheets"和app/assets/plugins"中的所有内容都被预编译为 public/assets

was created. Everything in "app/assets/javascripts", "app/assets/stylesheets" and "app/assets/plugins" were precompiled to public/assets

效果

app/assets/javascripts/login.js

能够在具有

<%= javascript_include_tag 'login.js' %>

什么不起作用

属于插件"的文件.

app/assets/plugins/myPlugin1/somefile.js

被预编译为

public/assets/myPlugin1/somefile.js

但是当我跑步时

<%= javascript_include_tag 'plugins/myPlugin1/somefile.js' %>

它试图访问

/javascripts/plugins/myPlugin1/somefile.js

根据我的开发经验，正确的路径应该是:

when the correct path, according to my experience in development, would be:

/myPlugin1/somefile-(some hex hash).js

<小时>

因此，如您所见，在生产中，我遇到了与未添加时相同的问题

---

So, as you can see, in production I'm experiencing the same issue as when I haven't added

config.assets.paths << Rails.root.join("app", "assets")

到 application.rb

to application.rb

可能是什么问题?

推荐答案

你可以这样:

Dir.glob("#{Rails.root}/app/assets/plugins/**/").each do |path|
  config.assets.paths << path
end

或者设置每个插件，一个一个像:

Or set each plugin, one by one like:

config.assets.paths << Rails.root.join("app", "assets", "plugins", "myPlugin")

但是如果您在 myPlugin 目录上有子目录，则不会加载每个文件.因此，第一个选项可能更适合您.

But if you have subdirectories on that myPlugin directory would not load every file. So the first option might be better for you.
