问题描述
我正在使用 Ruby 2.0.0-p247 和 Rails 4.0.0
如果我像这样制作一个最小的 Rails 4 站点:
If I make a minimal Rails 4 site like this:
rails new minimal
cd minimal
rails generate controller home index
tee config/routes.rb <<EOF
Minimal::Application.routes.draw do
root 'home#index'
end
EOF
然后用
rake assets:precompile
它生成如下资产:
I, [2013-09-04T17:05:36.992951 #3549] INFO -- : Writing /WORKINGDIR/minimal/public/assets/application-723d1be6cc741a3aabb1cec24276d681.js
I, [2013-09-04T17:05:37.052303 #3549] INFO -- : Writing /WORKINGDIR/minimal/public/assets/application-f1a14051f17824976271b9c0460232f0.css
但是如果我在生产模式下启动服务器，
But if I start the server in production mode, with
RAILS_ENV=production rails s
HTML 中生成的 URL 不指向预编译文件:
The generated URLs in the HTML don't point at the precompiled files:
<link data-turbolinks-track="true" href="/stylesheets/application.css" media="all" rel="stylesheet" />
<script data-turbolinks-track="true" src="/javascripts/application.js"></script>
我更希望:
<link data-turbolinks-track="true" href="assets/application-f1a14051f17824976271b9c0460232f0.css" media="all" rel="stylesheet" />
<script data-turbolinks-track="true" src="/assets/application-723d1be6cc741a3aabb1cec24276d681.js"></script>
默认的 config/environments/production.rb 设置说使用摘要:
The default config/environments/production.rb settings say to use digests:
config.assets.digest = true
但是好像被选择性忽略了?
But it seems to be selectively ignored?
我错过了什么吗?
更新:
我刚刚在 Rails 4.2.3 中对此进行了测试，这似乎已修复，但是我们需要将更多环境变量传递给 rails s 命令以在生产模式下启动:
I just tested this in Rails 4.2.3 and this appears to be fixed, however we need to hand a few more environment variables into the rails s command to start in production mode:
SECRET_KEY_BASE=$(rake secret) RAILS_SERVE_STATIC_FILES=true RAILS_ENV=production rails s
推荐答案
在我写这个问题的时候，我看到了这篇博客文章，它表明这是一个错误.
While I was writing up this question I came across this blog post which suggests it is a bug.
http://railsblog.kieser.net/2013/08/rails4-phusion-passenger-asset-pipeline.html
在各种建议中，只需将编译回退设置为 true...
Of the various suggestions, just setting the compilation fallback true...
config.assets.compile = true
似乎足以让 Rails 生成适当消化的 URL:
seems to be sufficient to kick Rails in to generating appropriately digested URLs:
<link data-turbolinks-track="true" href="/assets/application-f1a14051f17824976271b9c0460232f0.css" media="all" rel="stylesheet" />
<script data-turbolinks-track="true" src="/assets/application-723d1be6cc741a3aabb1cec24276d681.js"></script>
另一个建议，明确设置 RAILS_ENV 和 RAILS_GROUPS 似乎在预编译文件上生成不同的摘要字符串，但无论如何它们似乎总是与生成的 HTML 匹配.
The other suggestion, explicitly setting RAILS_ENV and RAILS_GROUPS seemed to produce different digest strings on the precompiled files, but they always seem to match up with the generated HTML regardless.
这篇关于资产生成的文件:预编译与最小 rails 4 站点中由 stylesheet_link_tag(缺少摘要)生成的 url 不匹配的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
