使用Dokku在Digital Ocean上运行Rails 4应用程序.用户可以通过回形针上传图像.我可以上传图像,应用程序运行良好并显示所有图像.一旦我做了一个像文本更改的小改动,我运行$ git push dokku master,所有上传的图像404.

模型:

class ProductImage < ActiveRecord::Base
  has_attached_file :image, default_url: "/images/:style/missing.png", 
  :path =>":rails_root/public/system/:attachment/:id/:basename_:style.:extension",
  :url =>"/system/:attachment/:id/:basename_:style.:extension",
  styles: { thumb: ["64x64#", :jpg], medium: ['200x200>', :jpg], 
    large: ['400x400>', :jpg] }
  validates_attachment_content_type :image, content_type: /\Aimage\/.*\Z/

  belongs_to :product
end

我有rails_12factor gem.这是配置文件:

Rails.application.configure do
  config.cache_classes = true
  config.eager_load = true
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true
  config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
  config.assets.js_compressor = :uglifier
  config.assets.compile = true
  config.assets.digest = true
  config.log_level = :debug
  config.i18n.fallbacks = true
  config.active_support.deprecation = :notify
  config.log_formatter = …
