Rails资源预编译只是不工作 [英] Rails Assets Precompile just not working

问题描述

我将Rails应用程序推送到Heroku，并继续运行以下问题：

我将保存对主css.scss文件所做的更改（在资产/样式表）或资产/图片中的图片，推送到git，将其推送到heroku并重新加载页面，只是为了发现这些资源根本没有加载。

这也是本地服务器上的一个小问题，但输入：

  rake资产：预编译
  

并重新加载本地服务器通常可以工作，而

  heroku run rake assets：precompile 
  

，然后重新推送什么都不做。

值得注意的是，在我的 config / application.rb 中（某些）：

 ＃启用资产管道
 config.assets.enabled = true如果定义了
 
（Bundler）
＃如果在部署到产品之前预编译资产，请使用以下命令：
 Bundler.require（* Rails.groups（：assets =>％ w（开发测试）））
＃如果你希望你的资产在生产中被懒惰地编译，使用这行
 Bundler.require（：default，：assets，Rails.env）
 end 
  

位于 config / environments / production.rb ：

 ＃禁用Rails的静态资产服务器（Apache或nginx已经这样做）
 config.serve_static_assets = false 
 
 ＃压缩JavaScript和CSS 
 config.assets.compress = true 
 
＃如果预编译资产是错过了
 config.assets.compile = true 
 
＃为资产URL生成摘要
 config.assets.digest = true 
  

另外可能的兴趣是，当我推送到heroku时，它说，除此之外，这是：

 为Rails资产管道准备应用程序
检测到的manifest.yml，假设资产是在本地编译的
 -----> Rails插件注入
注入rails_log_stdout 
注入rails3_serve_static_assets 
  

和

 使用Bundler安装依赖关系版本1.3.0.pre.5 
运行：bundle install --without development：test --path vendor / bundle --binstubs vendor / bundle / bin --deployment 
  

我学习了Rails 3，并没有真的知道资产管道与以前版本中的资产管道有什么不同，所以对不起，如果我是一个白痴，并在我的配置文件中设置重叠和/或矛盾的设置。

希望得到任何帮助。这是一个令人头疼的问题。看起来可能是你将你的本地编译资源添加到git中并推送它们因此Heroku不会在推送时编译您的资产。检查以确保您没有将公共/资产目录添加到git中。

I've pushed a Rails app to Heroku and keep on running into the following problem:

I'll save changes to my main css.scss file (in assets/stylesheets) or to images in assets/images, push to git, push that to heroku, and reload the page, only to find out that these assets haven't been loaded at all.

This was also a slight problem on the local server, but entering:

rake assets:precompile

and reloading the local server usually worked, whereas doing

heroku run rake assets:precompile

and then re-pushing does nothing. I've fished around for info and haven't found anything particularly helpful.

Of note, in my config/application.rb (some of these the result of said fishing around):

# Enable the asset pipeline
config.assets.enabled = true

if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  Bundler.require(*Rails.groups(:assets => %w(development test)))
  # If you want your assets lazily compiled in production, use this line
  # Bundler.require(:default, :assets, Rails.env)
end

in config/environments/production.rb:

# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = false

# Compress JavaScripts and CSS
config.assets.compress = true

# Fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true

# Generate digests for assets URLs
config.assets.digest = true

Of additional possible interest, when I push to heroku, it says, among other things, this:

Preparing app for Rails asset pipeline
       Detected manifest.yml, assuming assets were compiled locally
-----> Rails plugin injection
       Injecting rails_log_stdout
       Injecting rails3_serve_static_assets

and

Installing dependencies using Bundler version 1.3.0.pre.5
Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin --deployment

I learned with Rails 3 and don't really know how the assets pipeline differs from what was available in previous version, so sorry if I'm being an idiot and putting overlapping and/or contradictory settings in my config files.

Would appreciate any help. This has been a headache.

解决方案

It looks like it could be that you are add your locally compiled assets to git and pushing them and as a result Heroku is not compiling your assets on push. Check to make sure you are not adding the public/assets directory to git.
