Rails 3和Communityengine的照片上传

Question

我得到了我的Rails应用程序使用社区发动并立即运行，但不知何故我无法使图像上传工作。

在标准安装时，我尝试上传图片我总是会得到这个错误：

Photo /tmp/stream20130319-18602-13k89ab.gif is not recognized by the 'identify' command. 

ImageMagick的正确安装和识别命令的作品。/tmp /文件夹的权限也是正确的。所以我对这个问题一无所知=（。

要解决此问题，我尝试使用Amazon S3进行存储，因为我不介意图像来自哪里（请参阅here）。我复制了正确填写的s3 .yml到应用程序/配置/文件夹，我使用的宝石“AWS-SDK”在我的Gemfile如下建议：Paperclip;我更新application_config.rb这样的：

:photo => { 
    :missing_thumb => '/assets/icon_missing_thumb.gif', 
    :missing_medium => "/assets/icon_missing_medium.gif", 
    :paperclip_options => { 
     :storage => 's3', 
     :styles => { 
     :thumb => { 
      :geometry => '100x66#', 
      :processors => [:cropper] 
     }, 
     :medium => { 
      :geometry => '300x200#', 
      :processors => [:cropper] 
     }, 
     :large => { 
      :geometry => '600x400#', 
      :processors => [:cropper] 
     }, 
     :original => "1024>"  
     } 
    }, 
    :validation_options => { 
     :max_size => 3, 
     :content_type => ['image/jpg', 'image/jpeg', 'image/pjpeg', 'image/gif', 'image/png', 'image/x-png']   
    } 
    }, 

    :feature => { 
    :use_thumbs => true, 
    :paperclip_options => { 
     :storage => 's3', 
     :styles => { 
     :thumb => "100x66#", 
     :medium => '300x200#', 
     :large => "600x400#", 
     :original => '1024>'    
     } 
    }, 
    :validation_options => { 
     :max_size => 3, 
     :content_type => ['image/jpg', 'image/jpeg', 'image/pjpeg', 'image/gif', 'image/png', 'image/x-png']   
    } 
    }, 

    :clipping => { 
    :paperclip_options => { 
     :storage => 's3', 
     :styles => { 
     :thumb => "100x66#", 
     :medium => "300x200#", 
     :large => "600x400#", 
     :original => '1024>'  
     } 
    }, 
    :validation_options => { 
     :max_size => 3, 
     :content_type => ['image/jpg', 'image/jpeg', 'image/pjpeg', 'image/gif', 'image/png', 'image/x-png']    
    } 
    },

任何人都可以帮我吗？我真的坚持这一点。

Answer 1

我现在解决了这个问题！ CommunityEngine的Jquery-Bootstrap分支使用回形针2.4.5，并在较新的版本中解决此问题。

我在Github上分叉了Communityengine，并将回形针依赖项更新为2.7.4。 在community_engine.gemspec只需更换这一点：

s.add_dependency(%q<paperclip>, ["~> 2.4.3"]) 

与此：

s.add_dependency(%q<paperclip>, ["~> 2.7.4"]) 

的另一个问题是，需要较新版本“斗”，而不是“BUCKET_NAME”中的S3凭据（我搞砸了这样）。

Answer 2

回形针2.4.5仍然使用aws-s3宝石。

您的Gemfile行更改为：

gem "aws-s3", :require => "aws/s3" 

或使用主分支，而不是稳定的版本（这当然有一些涉及的风险）：

gem 'paperclip', :git => "git://github.com/thoughtbot/paperclip.git" 
gem "aws-sdk" 

UPDATE：回形针2.5 .0于2012年1月13日发布，现在使用aws-sdk

对于第二个问题，我正在更新它swer

的主要问题是，你需要将下面的代码移动到它自己的初始化文件：

if Rails.env == "production" 
    S3_CREDENTIALS = { :access_key_id => ENV['S3_KEY'], :secret_access_key => ENV['S3_SECRET'], :bucket => "ourbucket"} 
else 
    S3_CREDENTIALS = Rails.root.join("config/s3.yml") 
end 

然后，你应该将下面一行添加到您的模型，你有* has_attached_file：照片*要添加的行是。

:s3_credentials => S3_CREDENTIALS, 

这就是你之前缺少的东西。

此外，当您声明您的存储桶名称时，请确保它适用于我们的标准。如果您使用其他位置之一，则必须适当更新路径。

希望这会有所帮助！
