Ruby on Rails，Paperclip，亚马逊AWS S3和Heroku

我尝试了两天，让我的所有网站都通过Heroku和亚马逊AWS S3在互联网上工作（存储我的图像），但……我无法做到！

为了简化，我想使用带有回形针的Heroku和Amazon AWS S3来上传图片并进行显示。

我遵循了很多教程但是，这个总结了我所做的一切： https ： //devcenter.heroku.com/articles/paperclip-s3

上传系统适用于本地的基本存储，但如果我按照教程并将此代码放在我的环境中，我就会出错

config.paperclip_defaults = { :storage => :s3, :s3_credentials => { :bucket => ENV['S3_BUCKET_NAME'], :access_key_id => ENV['AWS_ACCESS_KEY_ID'], :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY'] } } 

首先是我的代码，然后我会写出我在本地的错误，以及我尝试在Internet上测试时的错误（Heroku打开）。

我的代码：

develpment.rb：

 Blabla::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 # Do not eager load code on boot. config.eager_load = false # 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 # Raise an error on page load if there are pending migrations config.active_record.migration_error = :page_load # Debug mode disables concatenation and preprocessing of assets. # This option may cause significant delays in view rendering with a large # number of complex assets. config.assets.debug = true config.paperclip_defaults = { :storage => :s3, :s3_credentials => { :bucket => ENV['S3_BUCKET_NAME'], :access_key_id => ENV['AWS_ACCESS_KEY_ID'], :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY'] } } end 

production.rb：

 Blabla::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 thread 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 # Enable Rack::Cache to put a simple HTTP cache in front of your application # Add `rack-cache` to your Gemfile before enabling this. # For large-scale production use, consider using a caching reverse proxy like nginx, varnish or squid. # config.action_dispatch.rack_cache = 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.js_compressor = :uglifier # config.assets.css_compressor = :sass # Do not fallback to assets pipeline if a precompiled asset is missed. config.assets.compile = false # Generate digests for assets URLs. config.assets.digest = true # Version of your assets, change this if you want to expire all your assets. config.assets.version = '1.0' # 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 # Set to :debug to see everything in the log. config.log_level = :info # 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 in app/assets folder are already added. # config.assets.precompile += %w( search.js ) # 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 can not be found). config.i18n.fallbacks = true # Send deprecation notices to registered listeners. config.active_support.deprecation = :notify # Disable automatic flushing of the log to improve performance. # config.autoflush_log = false # Use default logging formatter so that PID and timestamp are not suppressed. config.log_formatter = ::Logger::Formatter.new config.paperclip_defaults = { :storage => :s3, :s3_credentials => { :bucket => ENV['S3_BUCKET_NAME'], :access_key_id => ENV['AWS_ACCESS_KEY_ID'], :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY'] } } end 

herocu配置：

 AWS_ACCESS_KEY_ID: AKI******************** AWS_SECRET_ACCESS_KEY: Aiqpdg****************** DATABASE_URL: ************************** HEROKU_POSTGRESQL_CYAN_URL: *********************** KOIDEPLOY_TOKEN: ******************** S3_BUCKET_NAME: pylo***** 

我的初始化程序paperclip.rb：

 Paperclip::Attachment.default_options[:url] = ':s3_domain_url' Paperclip::Attachment.default_options[:path] = '/:class/:attachment/:id_partition/:style/:filename' Paperclip::Attachment.default_options[:s3_host_name] = 's3-us-west-2.amazonaws.com' 

错误当我在本地尝试时：

我可以上传图片，但是当我提交时：

 ArgumentError in PhotosController#create missing required :bucket option respond_to do |format| 

当我使用“heroku open”命令在互联网上尝试时出错：

我可以选择一个文件但是当我提交时：

 We're sorry, but something went wrong. If you are the application owner check the logs for more information. 

请帮我 ：）

编辑：在我的AWS S3帐户上，我刚刚在eu aera上创建了一个存储桶。 我成功地在heroku上看到我的网站，问题是上传

我的照片模型：photo.rb：

 class Photo < ActiveRecord::Base has_attached_file :image end 

我的show.erb.html文件：

Answer 1

以前有这个问题！

通过将桶变量放入模型本身（实时代码）来解决它：

  #app/models/image.rb has_attached_file :image, :styles => { :medium => "x300", :thumb => "x100" }, :default_url => "**********", :storage => :s3, :bucket => '*****', :s3_credentials => S3_CREDENTIALS #config/application.rb config.paperclip_defaults = { :storage => :s3, :s3_host_name => 's3-eu-west-1.amazonaws.com' } #config/initializers/s3.rb if Rails.env == "production" # set credentials from ENV hash S3_CREDENTIALS = { :access_key_id => ENV['S3_KEY'], :secret_access_key => ENV['S3_SECRET'], :bucket => "*****"} else # get credentials from YML file S3_CREDENTIALS = Rails.root.join("config/s3.yml") end #config/application.yml ([figaro][1] gem) S3_KEY: ******** S3_SECRET: ********** 

我们的生产中也有这个.rb：

 #app/environments/production.rb config.action_controller.asset_host = "//#{ENV['FOG_DIRECTORY']}.s3.amazonaws.com" 

ENV['FOG_DIRECTORY']是桶名，并且还有一个用于不同的区域。 这里有一个非常好的资源 （15个upvotes的答案……不是接受的答案）

试试这个url。 这会给你一个帮助。

Answer 3

你可以发布你的Photo课程吗？

从日志

 Paperclip::Error (Photo model missing required attr_accessor for 'image_file_name'): 

它看起来像你没有在你的类上定义has_attached_file 。

从您链接的教程：

 class Friend < ActiveRecord::Base # You will need to use attr_accessible if you are # using Rails config setting `whitelist_attributes = true` attr_accessible :avatar # This method associates the attribute ":avatar" with a file attachment has_attached_file :avatar, styles: { thumb: '100x100>', square: '200x200#', medium: '300x300>' } end 

如果你有这个（或类似的东西），那么你可能需要进行迁移才能在数据库中获取该列：

 add_attachment :photos, :image 

这会将正确的列添加到您的photos表中。

使用has_attached_file和表上的列，我认为你不应该有任何（或至少相同的）问题
