Rails 4资产管道不会使用asset_path对其他资产的引用来覆盖资产 [英] Rails 4 asset pipeline doesn't overwrite assets with asset_path references to other assets

问题描述

因此，我们在资产管道摘要方面存在一个小问题，因为我们有许多HTML模板作为资产（用于AngularJS），并且我们使用 asset_path helper。不幸的是，由于资产预编译步骤（和Heroku）如何检查更改，因此对模板进行更改并不会导致重新编译JavaScript文件。

因此，基本上像 application.coffee.erb 这样的文件可能类似于：

  url ='<％= asset_path（'views / template.html'）％>'
  

当我们运行 rake assets：precompile 时，它会变成 /assets/views/template-1023911231.html which具有摘要值，但是如果 template.html.slim 发生更改，则摘要将更改，但自 application.coffee.erb 并没有从根本上改变它没有重新编译，并继续指向旧的摘要。

想法？解决方案？实际上，这对我来说似乎是一个错误。

更新

目前我拥有的最佳解决方案是更新资产版本在application.rb中，如果我们需要更改我们的HTML模板资产，但没有一个javascript已经改变。 解决方案

在此处建议，其中涉及使用 depend_on 或 depend_on_asset 指令。在我的情况下，将此添加到 .js.erb 文件中工作：

  // = depends_on_asset views / template.html 
 $ b url ='<％= asset_path（'views / template.html'）％>'
  

只要根据需要更改 views / template.html ，就会重新编译此文件。

So we have a small problem with asset pipeline digests in that we have a number of HTML templates as assets (for AngularJS) and we references the paths for these assets in a Javascript file with the asset_path helper. Unfortunately because of how the asset precompile step (and Heroku) check for changes, making changes to a template does not cause the javascript file to be recompiled.

So basically in a file like application.coffee.erb we might have something like:

url = '<%= asset_path('views/template.html') %>'

And when we run rake assets:precompile that will get turned into /assets/views/template-1023911231.html which has a digest value but if template.html.slim is changed the digest will change but since application.coffee.erb has not fundamentally changed it isn't recompiled and continues to point to the old digest.

Thoughts? Solutions? This seems like a bug to me actually.

Update

Currently the best solution I have is to update the asset version in application.rb if we need to change our HTML template assets but none of the javascript has changed.

解决方案

A solution was suggested here which involves using the depend_on or depend_on_asset directive. In my case adding this to the .js.erb file works:

//= depend_on_asset views/template.html

url = '<%= asset_path('views/template.html') %>'

This will recompile this file any time there is a change to views/template.html as desired.
