与Padrino一起使用回形针

背景：我正在用Padrino，Ruby 1.9.2， HAML和Heroku构建一个简单的博客。我希望帖子索引拥有类似杂志的外观 。对于索引中的每个帖子，用户都应该看到标题，内容 挑逗者和图片。我的问题是附加图像。与Padrino一起使用回形针

问题：我一直在尝试使用Paperclip gem将图像 附加到每个帖子。 Heroku将从亚马逊S3仓中捕捉实际图像。 到目前为止，当我尝试运行迁移时，我得到的错误：

​​

它看起来像回形针就不会加载，但有从哪里获得 卡住。

详情： - 问：当我“尝试运行迁移”时，我正在做什么？ --a：我把下列的迁移文件夹

class AddPictureToPost < ActiveRecord::Migration 
    def self.up 
    change_table :posts do |t| 
     t.has_attached_file :picture 
    end 
    end 

    def self.down 
    drop_attached_file :posts, :picture 
    end 
end

然后运行 ​​“padrino耙AR：迁移”

--Q：我有回形针在Gemfile中列出？ - 答：是的。

- 问：邮政模型是什么样的？ --a：

class Post < ActiveRecord::Base 
    has_attached_file :picture, 
    :storage => :s3, 
    :bucket => 'blog_images', 
    :s3_credentials => { 
     :access_key_id => ENV['S3_KEY'], 
     :secret_access_key => ENV['S3_SECRET'] 
    } 
end

--Q：什么是app.rb样子？ --A：

class Blog < Padrino::Application 
    register Padrino::Rendering 
    register Padrino::Mailer 
    register Padrino::Helpers 

    enable :sessions 

    get '/' do 
    haml :index 
    end 
end

- 问：boot.rb是什么样子的？ --A：

PADRINO_ENV = ENV["PADRINO_ENV"] ||= ENV["RACK_ENV"] ||= 
"development" unless defined?(PADRINO_ENV) 
PADRINO_ROOT = File.expand_path('../..', __FILE__) unless defined? 
(PADRINO_ROOT) 

require 'rubygems' unless defined?(Gem) 
require 'bundler/setup' 
Bundler.require(:default, PADRINO_ENV) 

Padrino.before_load do 
end 

Padrino.after_load do 
end 

Padrino.load!

- 问：完整的错误输出是什么样的？ --a：

没有迁移问题！我修正了迁移，应该读取“t.string”而不是“t.has_file_attached”：P但是，当我尝试运行应用程序时，仍然收到相同的错误 – haiqus 2011-12-23 05:16:38

imagemagick已安装？你在使用rvm和/或bundler吗？ – froderik 2011-12-23 07:41:38

imagemagick安装最后我检查。我会仔细检查确认。我使用捆绑器，没有任何困难 – haiqus 2011-12-31 01:54:38

回形针是rails不可知的，所以你需要把boot.rb在Padrino.before_load这样的：

ActiveRecord::Base.send(:include, Paperclip::Glue) 
    File.send(:include, Paperclip::Upfile) 

    Paperclip.options[:logger] = Padrino.logger

heroku下最后运行迁移，你应该先运行本地padrino rake gen这将创建一个Rakefile所以你应该能够简单地运行：heroku rake ar:migrate

谢谢！我在这个项目上休息了一下......我很快就会让你知道你的建议是如何运作的 – haiqus 2011-12-31 01:55:51

好吧......我得到了“未初始化的常量Paperclip :: Schema（NameError）”以及建议的添加boot.rb – haiqus 2011-12-31 02:37:53

是的，对不起，我使用了主分支，现在我已经更新了代码以使用2.4.5版本的回形针。 – DAddYE 2012-01-02 10:49:45
