本文介绍了在Heroku上使用Compass:/ tmp用于远程和本地样式表的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我目前正在Heroku上使用Compass,使用Heroku知识推荐的基础。 Heroku有一个只读文件系统,因此编译的样式表需要存储在/ tmp中。这在Heroku上可以很好地工作。然而,在本地,Rails希望在/ public / stylesheets中找到样式表(当通过 = stylesheet_link_tag'screen.css',:media =>'screen,projection'调用时) 。

为了解决这个问题,我使用 ln -s tmp / stylesheets / screen.css在/ public / stylesheets中创建了符号链接public / stylesheets / screen.css ,这似乎工作。

有没有办法解决这个问题,而不使用符号链接,也许在Rails中改变一些配置?



这是我的config / initializers / compass.rb:

  require'compass'
require'compass / app_integration / rails'
Compass :: AppIntegration :: Rails.initialize!

#Heroku需要:
需要'fileutils'
FileUtils.mkdir_p(Rails.root.join(tmp,stylesheets))

Compass :: AppIntegration :: Rails.initialize!

Rails.configuration.middleware.delete('Sass :: Plugin :: Rack')
Rails.configuration.middleware.insert_before('Rack :: Sendfile','Sass :: Plugin ::'Rack')

Rails.configuration.middleware.insert_before('Rack :: Sendfile','Rack :: Static',
:urls => ['/ stylesheets'] ,
:root =>#{Rails.root} / tmp)

这里是我的配置/ compass.rb:

  project_type =:rails 
project_path = Compass :: AppIntegration :: Rails.root

#在部署时将其设置为您项目的根目录:
http_path =/

#Heroku必需(原始注释:
css_dir ='tmp / stylesheets'
#css_dir =public / stylesheets / compiled

sass_dir ='app / views / stylesheets'

environment = Compass :: AppIntegration :: Rails.env

任何帮助将不胜感激。

解决方案

我是实际上我们正准备用我们的Heroku托管的Rails应用程序来设置Compass,所以欢呼我给了我一个解决方案的借口。 :)



答案很简单:



修改'config / compass.rb':

  project_type =:rails 
project_path = Compass :: AppIntegration :: Rails.root

http_path = /

environment = Compass :: AppIntegration :: Rails.env
if environment =='production'
css_dir =tmp / stylesheets
sass_dir = app / views / stylesheets
else
css_dir =public / stylesheets
sass_dir =app / stylesheets
end

然后修改'config / initializers / compass.rb':

  require'compass'
require'compass / app_integration / rails'
Compass :: AppIntegration :: Rails.initialize!

需要'fileutils'
FileUtils.mkdir_p(Rails.root.join(tmp,stylesheets))

environment = Compass :: AppIntegration: :Rails.env
if environment =='production'
Compass :: AppIntegration :: Rails.initialize!

Rails.configuration.middleware.delete('Sass :: Plugin :: Rack')
Rails.configuration.middleware.insert_before('Rack :: Sendfile','Sass :: Plugin ::'Rack')

Rails.configuration.middleware.insert_before('Rack :: Sendfile','Rack :: Static',
:urls => ['/ stylesheets'] ,
:root =>#{Rails.root} / tmp)
结束

...和瞧,你很好。


I'm currently using Compass with Heroku using this configuration recommended on the Heroku knowledge base. Heroku has a read-only file system, and so the compiled stylesheets need to be stored in /tmp. This works fine remotely on Heroku; locally, however, Rails expects to find stylesheets in /public/stylesheets (when called through = stylesheet_link_tag 'screen.css', :media => 'screen, projection').

In order to solve the problem, I have created symbolic links in /public/stylesheets using ln -s tmp/stylesheets/screen.css public/stylesheets/screen.css and that seems to work.

Is there a way to solve this problem without using symbolic links, perhaps by changing some configuration in Rails? I've poked around without much success.

Here is my config/initializers/compass.rb:

require 'compass'
require 'compass/app_integration/rails'
Compass::AppIntegration::Rails.initialize!

# Required for Heroku:
require 'fileutils'
FileUtils.mkdir_p(Rails.root.join("tmp", "stylesheets"))

Compass::AppIntegration::Rails.initialize!

Rails.configuration.middleware.delete('Sass::Plugin::Rack')
Rails.configuration.middleware.insert_before('Rack::Sendfile', 'Sass::Plugin::Rack')

Rails.configuration.middleware.insert_before('Rack::Sendfile', 'Rack::Static',
    :urls => ['/stylesheets'],
    :root => "#{Rails.root}/tmp")

And here is my config/compass.rb:

project_type = :rails
project_path = Compass::AppIntegration::Rails.root

# Set this to the root of your project when deployed:
http_path = "/"

# Necessary for Heroku (original commented out:
css_dir   = 'tmp/stylesheets'
#css_dir = "public/stylesheets/compiled"

sass_dir  = 'app/views/stylesheets'

environment = Compass::AppIntegration::Rails.env

Any help would be greatly appreciated.

解决方案

I was actually just about to set up Compass with our Rails application, which is hosted on Heroku, so cheers for giving me an excuse to work through this. :)

The answer is simple:

Modify 'config/compass.rb':

project_type = :rails
project_path = Compass::AppIntegration::Rails.root

http_path = "/"

environment = Compass::AppIntegration::Rails.env
if environment == 'production'
  css_dir = "tmp/stylesheets"
  sass_dir = "app/views/stylesheets"
else
  css_dir = "public/stylesheets"
  sass_dir = "app/stylesheets"
end

Then modify 'config/initializers/compass.rb':

require 'compass'
require 'compass/app_integration/rails'
Compass::AppIntegration::Rails.initialize!

require 'fileutils'
FileUtils.mkdir_p(Rails.root.join("tmp", "stylesheets"))

environment = Compass::AppIntegration::Rails.env
if environment == 'production'
  Compass::AppIntegration::Rails.initialize!

  Rails.configuration.middleware.delete('Sass::Plugin::Rack')
  Rails.configuration.middleware.insert_before('Rack::Sendfile', 'Sass::Plugin::Rack')

  Rails.configuration.middleware.insert_before('Rack::Sendfile', 'Rack::Static',
      :urls => ['/stylesheets'],
      :root => "#{Rails.root}/tmp")
end

... and voila, you're good.
