我以前曾多次使用asset_sync gem取得了巨大成功,但在Rails 4.0.3项目中使用它似乎导致了问题.
资产被上传,散列和gzip到目标目录(我只使用默认的’assets’),但是当在临时/生产环境中运行应用程序时,路径不正确.
他们采取以下形式：
S3_DOMAIN.com/stylesheets/application.css
代替：
S3_DOMAIN.com/assets/application-HASH.css
还有其他人遇到过这个问题吗？我发现反转此行为的唯一方法是将config.assets.compile设置为true,但这在生产环境中不起作用.
以下是相关的配置文件：
## environments/staging.rb
config.serve_static_assets = false
config.assets.compress = true
config.assets.js_compressor = :uglifier
config.assets.css_compressor = :sass
# Have to set this to true to make asset_sync generate the correct links
config.assets.compile = false
config.assets.digest = true
config.assets.enabled = true
config.assets.initialize_on_precompile = true
config.action_controller.asset_host = "//#{Figaro.env.fog_directory}.s3.amazonaws.com"
config.action_mailer.asset_host = "//#{Figaro.env.fog_directory}.s3.amazonaws.com"
config.assets.prefix = "/assets"
config.assets.debug = false
config.assets.cache_store = :memory_store
##config/asset_sync.yml
defaults: &defaults
fog_provider: 'AWS'
aws_access_key_id: "<%= ENV['AWS_ACCESS_KEY_ID'] %>"
aws_secret_access_key: "<%= ENV['AWS_SECRET_ACCESS_KEY'] %>"
# To use AWS reduced redundancy storage.
# aws_reduced_redundancy: true
# You may need to specify what region your storage bucket is in
fog_region: <%= ENV['FOG_REGION'] %>
existing_remote_files: keep
# To delete existing remote files.
# existing_remote_files: delete
# Automatically replace files with their equivalent gzip compressed version
gzip_compression: true
# Fail silently. Useful for environments such as Heroku
# fail_silently: true
development:
<<: *defaults
enabled: false
test:
<<: *defaults
enabled: false
staging:
<<: *defaults
fog_directory: <%= ENV['FOG_DIRECTORY'] %>
production:
<<: *defaults
fog_directory: <%= ENV['FOG_DIRECTORY'] %>
解决方法
您需要在rails 4中运行与生产模式相关的所有资产.
例如：
rake assets:precompile RAILS_ENV=production
如果您在默认模式(开发)中运行它,则哈希值会有所不同,因此rails会将哈希值全部放在一起.
此外,您需要在启动服务器之前执行此操作,以便找到文件.
注意：我认为此更改是为了允许您在开发中缓存资产.
