我一直在寻找类似主题的解决方案，但我无法让它以某种方式工作。这是我的应用程序日志

我为用户使用设计
在我的 gem 文件中有
gem "mongoid-paperclip", :require => "mongoid_paperclip"
gem 'paperclip'
gem "aws-sdk"
在我的模型/photo.rb
has_mongoid_attached_file :image,
:path => ':attachment/:User/:id/:style.:extension',
:storage => :s3,
:s3_credentials => File.join(Rails.root, 'config', 's3.yml'), #s3.yml contain credentials
:styles => {
:small => ['32x32!', :png],
:medium => ['320x320!', :png, :jpg],
},
:convert_options => { :all => '-background white -flatten +matte' }
attr_accessible :image, :description
以我的形式
<%= form_for(@photo , :html => {:multipart => true} ) do |f| %>
<div class="field">
<%= f.label :image %><br />
<%= f.file_field :image %>
</div>
<% end %>
我已经尝试了许多解决方案，例如 add form_helper :multipart ，在我以前的应用程序中，这个模型和 gem 运行良好，我确信凭证是正确的。它只是告诉我这是一个成功的更新，但没有上传图像。我在哪里可以查找有关此问题的错误？或者我可以使用的任何工具？我真的坚持这一点并想通过它，而不是创建新的应用程序并祝好运。
