生產模式下不顯示圖像

Question

當我在Rails中切換到生產模式時，CSS正在加載，但不是圖像。我的CSS在我的/應用/資產/樣式表和在我的/應用/資產/圖像

我的CSS圖片鏈接與此圖片：

background:url("/assets/str.png") repeat #fbfbfb; 

我已經重新啓動的Rails，Nginx等客運

touch home/user/railsapp/tmp/restart.txt 
passenger-config restart-app 
sudo service nginx restart 

我曾嘗試：

rake assets:clobber 
rake assets:precompile 

我的密鑰是聯繫在一起的secrets.yml

我有這個在我的Nginx的配置：

passenger_enabled on; 
    passenger_app_env production; 

上還有什麼我可以嘗試任何建議？ 這裏是我的環境/ production.rb

rails.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 

    # Eager load code on boot. This eager loads most of Rails and 
    # your application in memory, allowing both threaded web servers 
    # and those relying on copy on write to perform better. 
    # Rake tasks automatically ignore this option for performance. 
    config.eager_load = true 

    # Full error reports are disabled and caching is turned on. 
    config.consider_all_requests_local  = false 
    config.action_controller.perform_caching = true 

    # Disable serving static files from the `/public` folder by default since 
    # Apache or NGINX already handles this. 
    config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present? 

    # Compress JavaScripts and CSS. 
    config.assets.js_compressor = :uglifier 
    # config.assets.css_compressor = :sass 

    # Added this to allow images to be compiled from assets folder. 
    config.assets.precompile += %w[*.png *.jpg *.jpeg *.gif] 

    # Do not fallback to assets pipeline if a precompiled asset is missed. 
    config.assets.compile = false 

    # `config.assets.precompile` and `config.assets.version` have moved to config/initializers/assets.rb 

    # Enable serving of images, stylesheets, and JavaScripts from an asset server. 
    # config.action_controller.asset_host = 'http://assets.example.com' 

    # 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 

    # Mount Action Cable outside main process or domain 
    # config.action_cable.mount_path = nil 
# config.action_cable.url = 'wss://example.com/cable' 
    # config.action_cable.allowed_request_origins = [ 'http://example.com', /http:\/\/example.*/ ] 

    # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies. 
    # config.force_ssl = true 

    # Use the lowest log level to ensure availability of diagnostic information 
    # when problems arise. 
    config.log_level = :debug 

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

    # Use a different cache store in production. 
    # config.cache_store = :mem_cache_store 

    # Use a real queuing backend for Active Job (and separate queues per environment) 
    # config.active_job.queue_adapter  = :resque 
    # config.active_job.queue_name_prefix = "zenapp_#{Rails.env}" 
    config.action_mailer.perform_caching = false 
    # Ignore bad email addresses and do not raise email delivery errors. 
    # Set this to true and configure the email server for immediate delivery to raise delivery errors. 
    # config.action_mailer.raise_delivery_errors = false 

    # Enable locale fallbacks for I18n (makes lookups for any locale fall back to 
    # the I18n.default_locale when a translation cannot be found). 
    config.i18n.fallbacks = true 

    # Send deprecation notices to registered listeners. 
    config.active_support.deprecation = :notify 

    # Use default logging formatter so that PID and timestamp are not suppressed. 
    config.log_formatter = ::Logger::Formatter.new 

    # Use a different logger for distributed setups. 
    # require 'syslog/logger' 
    # config.logger = ActiveSupport::TaggedLogging.new(Syslog::Logger.new 'app-name') 

    if ENV["RAILS_LOG_TO_STDOUT"].present? 
    logger   = ActiveSupport::Logger.new(STDOUT) 
    logger.formatter = config.log_formatter 
    config.logger = ActiveSupport::TaggedLogging.new(logger) 
    end 

    # Do not dump schema after migrations. 
    config.active_record.dump_schema_after_migration = false 
end 

我只是說了：

# Added this to allow images to be compiled from assets folder. 
config.assets.precompile += %w[*.png *.jpg *.jpeg *.gif] 

到production.rb

UPDATE

我甚至改名爲我的.css到application.css.erb並將css更改爲

background-image: url(<%= asset_path 'str.png' %>) repeat #fbfbfb; 

它仍然無法正常工作。

你可以嘗試

background: url(image_path("str.png")) repeat #fbfbfb;
