Rails loads css files from public/assets instead o

问题:

I'm running in development mode. I'm editing .css files but not seeing changes. If I go to public/assets/ and rename application.css, I see changes (it can't find any styles). Why would it be using that file? Isn't that for production mode? I don't want to pre-compile all the time in dev mode. thanks. Environment files added below.

development.rb :

   Tcms::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

  # Only use best-standards-support built into browsers
  config.action_dispatch.best_standards_support = :builtin

  # Raise exception on mass assignment protection for Active Record models
  config.active_record.mass_assignment_sanitizer = :strict

  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  config.active_record.auto_explain_threshold_in_seconds = 0.5

  # Do not compress assets
  config.assets.compress = false

  # Expands the lines which load the assets
  config.assets.debug = true
end

production.rb :

Tcms::Application.configure do
  # Uncomment and set this to match your production URL. Used for emailing links to the CMS. (default: localhost:3000)
  # config.cms.site_domain = "www.example.com"

  # Configure your mail server's address below
  config.action_mailer.smtp_settings = {:address => 'mail.yourmailserver.com', :domain => config.cms.site_domain}

  # 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 = true

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

  # Don't fallback to assets pipeline if a precompiled asset is missed
  config.assets.compile = true

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

  # Defaults to nil and saved in location specified by config.assets.prefix
  # 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 = :info

  # Prepend all log lines with the following tags
  # config.log_tags = [ :subdomain, :uuid ]

  # Use a different logger for distributed setups
  # config.logger = ActiveSupport::TaggedLogging.new(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


  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  # config.active_record.auto_explain_threshold_in_seconds = 0.5
end

回答1:

As default, Rails will serve assets within /public and not compiling live, if these assets exists.

To get rid of it, either delete the assets within the public dir, or add the following line into you config/environments/development.rb

config.serve_static_assets = false

config.serve_static_assets configures Rails itself to serve static assets. Defaults to true

What version of rails are you running? Is this an app that upgraded from 2.x or 3.0.x to 3.1 or 3.2? This almost sounds like this app was pre-asset pipline. Here is a good tutorial on upgrading from pre-asset pipline to asset-pipline...

...also here is a good basic tutorial for asset pipeline...
