在开发环境中从管道中排除某些资产？

时间：2022-02-25 23:33:31

I would like to somehow prevent certain assets from being included in the asset pipeline in the development environment.

我想以某种方式阻止某些资产被包含在开发环境中的资产管道中。

So far, I have tried the following:

到目前为止，我尝试过以下方法：

# app/assets/javascripts/application.js.erb
<% if Rails.env.production? %>
//= require google_analytics_snippet
<% end %>

and

和

# app/assets/javascripts/application.js.erb    
<% if ENV['RACK_ENV'] == 'production' %>
//= require google_analytics_snippet
<% end %>

All I seem to be achieving is whether or not the //= require google_analytics_snippet line appears in the manifest. The actual code in the google_analytics_snippet.js file is never loaded, regardless of environment when I use either of these attempted solutions.

我似乎要实现的是// =需要google_analytics_snippet线是否出现在清单中。当我使用这些尝试的解决方案时，无论环境如何，都不会加载google_analytics_snippet.js文件中的实际代码。

Is there a way I can do this?

有没有办法可以做到这一点？

Edit:
I was using a javascript file called olark.js in my examples when I first posted this question. That was a bad choice of example since Olark has a rubygem which may solve the problem. I have changed the example because I am looking for the general form solution.

编辑：当我第一次发布这个问题时，我在我的例子中使用了一个名为olark.js的javascript文件。这是一个不好的选择，因为Olark有一个可以解决问题的rubygem。我已经改变了这个例子，因为我正在寻找一般的表格解决方案。

I've looked through the source of the sprockets and I found, that the directive preprocessor always runs before any engine. So, it's not possible to add any conditional logic into the directives section with ERB or other engine.

我查看了链轮的来源，我发现，指令预处理器总是在任何引擎之前运行。因此，使用ERB或其他引擎将指令逻辑添加到指令部分是不可能的。

The answer is yes, but if this is what you are trying to do:

答案是肯定的，但如果这是你想要做的：

<% if Rails.env.production? %> 
//= require google_analytics_snippet
<% end %>

try this instead:

试试这个：

<% if Rails.env.production?
require_asset "google_analytics_snippet"
end %>

Depending on your deployment environment you might look at the rack/olark gem.

根据您的部署环境，您可能会看到rack / olark gem。

You could then probably try something like this in your gemfile:

然后你可以在gemfile中尝试这样的东西：

group :production do
  gem 'rack-olark'
end

Just a thought..
