在Heroku上使用Compass:/ tmp远程和本地使用样式表

Question

我目前正在使用Heroku知识库推荐的配置使用Compass和Heroku .Heroku有一个只读文件系统,因此编译好的样式表需要存储在/ tmp中.这在Heroku上工作得很好; 但是,Rails希望在/ public/stylesheets中找到样式表(通过调用时= stylesheet_link_tag 'screen.css', :media => 'screen, projection').

为了解决这个问题,我在/ public/stylesheets中创建了符号链接ln -s tmp/stylesheets/screen.css public/stylesheets/screen.css,这似乎有效.

有没有办法解决这个问题而不使用符号链接,也许是通过改变Rails中的一些配置？我没有取得太大的成功.

这是我的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")

这是我的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

任何帮助将不胜感激.

Answer 1

我实际上正准备使用我们的Rails应用程序设置Compass,这个应用程序是在Heroku上托管的,所以欢呼为我提供借口来解决这个问题.:)

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!

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

...瞧,你很好.
