我现在使用Communityengine启动并运行了我的rails应用程序，但不知何故我无法使图像上传工作。
在标准安装中，当我尝试上传图像时，我总是会得到这个错误:
Photo /tmp/stream20130319-18602-13k89ab.gif is not recognized by the 'identify' command.
Imagemagick已正确安装，并且identify-命令正常工作。/tmp/文件夹的权限也正确。所以我对这个问题一无所知=
为了解决这个问题，我尝试使用Amazon S3进行存储，因为我不介意图像来自哪里(见这里)。我复制了正确填写的s3。将Yml文件放到applications/config/文件夹中。我在我的Gemfile中使用gem"aws-sdk"，如下所示:我更新了application_config。像这样::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']
}
},
当我尝试编辑用户配置文件或上传图像时，我得到这个错误:未初始化常量AWS::S3::Base这里有完整的跟踪:

Paperclip 2.4.5仍然使用aw -s3 gem。
将您的Gemfile行更改为:
gem "aws-s3", :require => "aws/s3"
或者使用主分支而不是稳定版本(这当然有一些风险):
gem 'paperclip', :git => "git://github.com/thoughtbot/paperclip.git"
gem "aws-sdk"
更新: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，我正在更新这个答案
最主要的问题是你需要把下面的代码移到它自己的初始化文件中: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，您应该将以下行添加到您的模型中，其中包含*has_attached_file:photo*要添加的行是。
:s3_credentials => S3_CREDENTIALS,
这是你以前错过的。
另外，当你声明你的桶名时，确保它是标准的。如果您使用其他位置之一，则必须适当地更新路径。
希望这对你有帮助!
我现在解决了这个问题!CommunityEngine的Jquery-Bootstrap分支使用了2.4.5的回纹针，这个问题在更新的版本中得到了解决。
我在Github上分叉了Communityengine，并将回形针依赖更新为2.7.4。只需将其替换为community_engine.gemspec:
s.add_dependency(%q<paperclip>, ["~> 2.4.3"])
s.add_dependency(%q<paperclip>, ["~> 2.7.4"])
另一个问题是，新版本在S3凭据中需要"bucket"而不是"bucket_name"(我这样搞砸了)。
