scss文件rails中的asset_path

我在生产中遇到asset_path问题。 Rails 3.1.1

#config/environments/development.rb Scc::Application.configure do # Settings specified here will take precedence over those in config/application.rb # In the development environment your application's code is reloaded on # every request. This slows down response time but is perfect for development # since you don't have to restart the web server when you make code changes. config.cache_classes = false # Log error messages when you accidentally call methods on nil. config.whiny_nils = true # Show full error reports and disable caching config.consider_all_requests_local = true config.action_controller.perform_caching = false # Don't care if the mailer can't send config.action_mailer.raise_delivery_errors = false # Print deprecation notices to the Rails logger config.active_support.deprecation = :log config.action_mailer.default_url_options = { :host => 'localhost:3000' } # Only use best-standards-support built into browsers config.action_dispatch.best_standards_support = :builtin # Do not compress assets config.assets.compress = false # Expands the lines which load the assets config.assets.debug = true end 

和

 #config/environments/production.rb Scc::Application.configure do # Settings specified here will take precedence over those in config/application.rb # Code is not reloaded between requests config.cache_classes = true # Full error reports are disabled and caching is turned on config.consider_all_requests_local = false config.action_controller.perform_caching = true # 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 # Don't fallback to assets pipeline if a precompiled asset is missed config.assets.compile = false # Generate digests for assets URLs config.assets.digest = true # Defaults to Rails.root.join("public/assets") # config.assets.manifest = YOUR_PATH # Specifies the header that your server uses for sending files # config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache # config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies. # config.force_ssl = true # See everything in the log (default is :info) # config.log_level = :debug # Use a different logger for distributed setups # config.logger = SyslogLogger.new # Use a different cache store in production # config.cache_store = :mem_cache_store # Enable serving of images, stylesheets, and JavaScripts from an asset server # config.action_controller.asset_host = "http://assets.example.com" # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added) # config.assets.precompile += %w( search.js ) # Disable delivery errors, bad email addresses will be ignored # config.action_mailer.raise_delivery_errors = false # Enable threaded mode # config.threadsafe! # Enable locale fallbacks for I18n (makes lookups for any locale fall back to # the I18n.default_locale when a translation can not be found) config.i18n.fallbacks = true # Send deprecation notices to registered listeners config.active_support.deprecation = :notify end 

我有以下代码：

 .right-bar-filler{ background:url(asset_path('right_bar_filler.jpg', image)) repeat-y; padding-top:0px; } 

在开发过程中，它最终成为：

 .right-bar-filler { background: url("/assets/right_bar_filler.jpg") repeat-y; padding-top: 0px; } 

在生产中它输出为：

 .right-bar-filler { background: url(asset_path("right_bar_filler.jpg", image)) repeat-y; padding-top: 0px; } 

我完全错过了什么？

感谢您的任何帮助。

Answer 1

这看起来不正确：

 .right-bar-filler{ background:url(asset_path('right_bar_filler.jpg', image)) repeat-y; padding-top:0px; } 

如果要使用asset_path帮助程序，则需要在erb标记内运行（<%%>）

 .right-bar-filler{ background:url(<%= asset_path('right_bar_filler.jpg', image) %>) repeat-y; padding-top:0px; } 

并确保正确命名文件，即example_filename.css.erb

更新 ：对不起，我没有注意到你使用的是SASS，而不是CSS。 我的上述答案不是你需要的。

试试这个：

 .right-bar-filler{ background:url(asset-path('right_bar_filler.jpg', image)) repeat-y; padding-top:0px; } 

即我认为资产路径助手在SASS中使用连字符，而不是下划线

你耙资产了吗：预编译？ 默认情况下，Rails不会在生产中编译资产。 建议的工作流程是在部署过程中编译资产。
