Paperclip 无法将图像上传到 S3

Question

我在将图像上传到 Amazon S3 时遇到问题。我已经安装了回形针 gem 和 gem 'aws-s3'。我的 Amazon S3 服务器是欧洲的：http://s3-eu-west-1.amazonaws.com

当我提交表单时，表单会再次呈现，因为未保存摄影师。我可以看到没有任何内容上传到云端。我看到消息“图像正常”。

我的控制器：

def savenew
    @photographer = Photographer.create(params[:photographers]) 
    @photographer.sort_order = Photographer.count + 1

    if @photographer.save   
      redirect_to :action => 'list', :id => params[:id] 
    else    
      render 'create', :id => params[:id]             
    end                                 
end     

我的模型：

    attr_accessor :flv_file_size, :flv_updated_at, :flv_content_type, :image_file_size, :image_updated_at, :image_content_type,
    :quicktime_file_size, :quicktime_updated_at, :quicktime_content_type

  has_attached_file :image,
    :storage => :s3,
    :bucket => 'mybucket',
    :path => "/photographer/image/:id/:filename",
    :s3_credentials => {
      :access_key_id => 'mykey',
      :secret_access_key => 'mykey'
    }

  has_attached_file :flv,
    :storage => :s3,
    :bucket => 'mybucket',
    :path => "/photographer/flv/:id/:filename",
    :s3_credentials => {
      :access_key_id => 'mykey',
      :secret_access_key => 'mykey'
    }

      has_attached_file :quicktime,
    :storage => :s3,
    :bucket => 'mybucket',
    :path => "/photographer/quicktime/:id/:filename",
    :s3_credentials => {
      :access_key_id => 'mykey',
      :secret_access_key => 'mykey'
    }

我的创建页面：

<h2>Movie</h2>

<h3>Create new movie</h3>

<%= link_to 'back to movie list', {:action => 'list', :id => params[:id]}, {:class => "margin-left"} %>

<div class="spacer">&nbsp;</div>
<%#= start_form_tag(:action => "savenew", :id => params[:id]) %>
<%= form_tag( {:action => "savenew", :id  => params[:id] },  :multipart => true ) do |f|%>
<%= render(:partial => "linkform", :object => @photographer) %>      



<p>
   <label for="submit">&nbsp;</label>
<%= submit_tag("create new") %>

<% end %>

Answer 1

AWS-S3 gem 与欧洲 S3 存储桶配合良好。

如果将其添加到enviroment.rb中：

AWS::S3::DEFAULT_HOST.replace "s3-eu-west-1.amazonaws.com"

Answer 2

AWS-S3 不适用于欧洲 S3 存储桶 - 您需要使用美国存储桶，因为结构不同。

Carrierewave/Fog 与欧洲水桶配合良好。

Answer 3

如果您使用的是较新版本的回形针，则需要使用 aws-sdk gem，而不是 aws-s3 gem。我有同样的问题。
