的内容不是他们所报道的内容

iinstall file.exe并添加

Paperclip.options[:command_path] = 'C:\Program Files (x86)\GnuWin32\bin'

到devlopement.rb

my pic.rb

class Pic < ActiveRecord::Base  belongs_to :user

    has_attached_file :image, :styles => { :medium => "300x300>" }
    validates_attachment_content_type :image, content_type: /\Aimage\/.*\z/ end

我的show.html.haml

= image_tag @pic.image.url
%h1= @pic.title
%p= @pic.description
%p
Pic by 
= @pic.user.try(:email)

%br
