我无法使用回形针上传图片。每当我选择文件并提交页面时，都会重新加载并显示“未选择文件”。

我的代码trip.rb

    class Trip < ActiveRecord::Base
       has_many :images
       accepts_nested_attributes_for :images, :allow_destroy => true
       attr_accessible :messages_attributes
    end

表格

    <%= f.fields_for :images do |image_fields| %> 
       <% if image_fields.object.new_record? %> 
         <%= image_fields.file_field :image %>  
       <% end %> 
    <% end %>

图片.rb

    class Image < ActiveRecord::Base
     belongs_to :trips

     has_attached_file :image, :styles => { :large => "640x480", :medium => "300x300>", :thumb => "100x100" },
     :storage => :s3,
     :bucket => 'Thrill',
     :s3_credentials => {
       :access_key_id => 'XXXXXXXXXXXX',
       :secret_access_key => 'xxxxxxxxxxxxxxxxxxxxx'
     }
    end

而且我还在我的 gem 文件中安装了gem 'rmagick'，这似乎是许多有类似问题的解决方案。但在我的情况下并非如此。

有什么想法可能是错的吗？谢谢！

更新

通过 Rails 控制台

Image.create :image => File.open('c:/sites/thrillb/app/assets/images/srf.jpg')

也不工作。
