我和我的团队数周以来一直试图解决这个问题,但无济于事。每次我们在生产服务器上预编译资产时,我们的应用程序都会开始加载所有资产两次(一次作为预编译脚本,然后再次作为每个资产单独加载)。此问题通常发生在预编译后的 2-5 天之间(换句话说,它会在中断前工作几天)。我真的不确定为什么会这样。
我见过很多其他人有同样的问题,但他们的问题总是与开发环境有关。但是,我们的应用程序的环境是在生产环境中。
这是我们的预编译方法:
rake assets:clean
rake assets:precompile
这是我的/config/environment.rb:
# Load the rails application
require File.expand_path('../application', __FILE__)
ENV['RAILS_ENV'] ||= 'production'
# Initialize the rails application
Myapp::Application.initialize!
这是我的 /config/environments/production.rb:
Myapp::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
# Code is not reloaded between requests
config.cache_classes = false
# 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 = true
# Generate digests for assets URLs
config.assets.digest = true
# BEGIN ICONIC PRECOMPILE ISSUE FIX
# add iconic path to precompile
config.assets.paths << Rails.root.join('app', 'assets', 'fonts')
# Precompile additional assets
config.assets.precompile += %w( .svg .eot .woff .ttf )
# END ICONIC PRECOMPILE ISSUE FIX
# 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 = :debug
# 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
而且,虽然我不明白你为什么需要它,但这是我的 /config/environments/development.rb:
Myapp::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
***更新*
根据建议的答案,我修改了我的环境/production.rb。现在看起来像这样:
Myapp::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
# Code is not reloaded between requests
config.cache_classes = false
# Full error reports are disabled and caching is turned on
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = true
# config.assets.debug = false
# 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
# BEGIN ICONIC PRECOMPILE ISSUE FIX
# add iconic path to precompile
# config.assets.paths << Rails.root.join('app', 'assets', 'fonts')
# Precompile additional assets
# config.assets.precompile += %w( .svg .eot .woff .ttf )
# END ICONIC PRECOMPILE ISSUE FIX
# 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 = :debug
# 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
我的所有资产现在都在预编译后立即加载两次,而不是解决我的问题。我不确定我在这里做错了什么。
这是我正在运行的命令:
rm -rf public/assets
rake assets:clean
rake assets:precompile
任何见解将不胜感激。谢谢!
