有没有办法让 Sprockets 接受没有扩展名的文件？

宝石： 链轮：2.10.1 导轨：4.0.2

Answer 1

为了预编译资产，您需要将任何没有扩展名的文件从应用程序/资产中移出到供应商/资产中。这是 sprockets 的一个已知问题，bower 在其自述文件中有一个警告，请参阅https://github.com/stve/bower/pull/4/files

或者您可以确保 app/assets 中的所有文件都具有扩展名，但这需要更多时间。

Answer 2

在您的 config/application.rb 文件中添加

initializer 'setup_asset_pipeline', :group => :all  do |app|
  # We don't want the default of everything that isn't js or css, because it pulls too many things in
  app.config.assets.precompile.shift

  # Explicitly register the extensions we are interested in compiling
  app.config.assets.precompile.push(Proc.new do |path|
    File.extname(path).in? [
      '.html', '.erb', '.haml',                 # Templates
      '.png',  '.gif', '.jpg', '.jpeg',         # Images
      '.eot',  '.otf', '.svc', '.woff', '.ttf', # Fonts
    ]
  end)
end

看起来像

module ProjectName
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de
    initializer 'setup_asset_pipeline', :group => :all  do |app|
      # We don't want the default of everything that isn't js or css, because it pulls too many things in
      app.config.assets.precompile.shift

      # Explicitly register the extensions we are interested in compiling
      app.config.assets.precompile.push(Proc.new do |path|
        File.extname(path).in? [
          '.html', '.erb', '.haml',                 # Templates
          '.png',  '.gif', '.jpg', '.jpeg',         # Images
          '.eot',  '.otf', '.svc', '.woff', '.ttf', # Fonts
        ]
      end)
    end
  end
end
