ruby-on-rails - Rails3とCommunityengineの写真のアップロード

Question

Communityengineを使用してRailsアプリケーションを起動して実行しましたが、どういうわけか画像のアップロードを機能させることができません。

標準インストールでは、画像をアップロードしようとすると常にこのエラーが発生します。

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

Imagemagickが正しくインストールされ、identify-commandが機能します。/tmp/フォルダーへのアクセス許可も正しいです。だから私はこの問題=（で無知です。

この問題を回避するために、画像がどこから来たのか気にしないので、ストレージにAmazon S3を使用しようとしました（ここを参照）。正しく入力されたs3.ymlをアプリケーションの/config/フォルダーにコピーしました。ここで提案されているように、 Gemfileでgem"aws-sdk"を使用しています。そして私はこのようにapplication_config.rbを更新しました：

: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']              
    }
  },

ユーザープロファイルを編集したり、画像をアップロードしたりしようとすると、次のエラーが発生します：初期化されていない定数AWS :: S3 :: Base Full Trace here：

Paperclip 2.4.5 は引き続き aws-s3 gem を使用します。

Gemfile 行を次のように変更します。

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

または、安定版の代わりに master ブランチを使用します (もちろんリスクが伴います):

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

更新: 2012 年 1 月 13 日にリリースされた Paperclip 2.5.0 は、aws-sdk を使用するようになりました

2番目の問題は、この回答を更新しています

主な問題は、次のコードを独自の初期化ファイルに移動する必要があることです。

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

次に、*has_attached_file :photo* があるモデルに次の行を追加する必要があります。追加する行は次のとおりです。

:s3_credentials => S3_CREDENTIALS,

これは、以前に欠けていたものです。

また、バケット名を宣言するときは、それが標準的なものであることを確認してください。他の場所のいずれかを使用する場合は、パスを適切に更新する必要があります。

お役に立てれば！

私は今この問題を解決しました！CommunityEngineのJquery-Bootstrapブランチはペーパークリップ2.4.5を使用しており、この問題は新しいバージョンで解決されています。

GithubでCommunityengineをフォークし、ペーパークリップの依存関係を2.7.4に更新しました。これを次のように置き換えてcommunity_engine.gemspecください：

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

これとともに：

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

もう1つの問題は、新しいバージョンではS3クレデンシャルに「bucket_name」ではなく「bucket」が必要だったことです（これは私がこのように台無しにしました）。
