权限被拒绝@ dir_s_mkdir - / listing

我不确定我做错了什么 . 带回形针的S3 .

在ListController中的Errno :: EACCES＃update允许拒绝@dir_s_mkdir - / listing提取的源（第44行附近）：

• def更新

• respond_to do | format |

• if @ listing.update（listing_params）

• format.html {redirect_to @listing，notice：'Listing was 46.successfully updated.'}

• format.json {render：show，status :: ok，location：@listing} 48 else

Listing_controller.rb

<p id="notice"><%= notice %></p>

<div class="row">
  <div class="col-md-6">
    <div class="thumbnail">
      <%= image_tag @listing.image.url %>
    </div>
  </div>
  <div class="col-md-6">
    <h3><%= @listing.name %></h3>
    <p><%= number_to_currency (@listing.price) %></p>
    <p><%= @listing.description %></p>
  </div>
</div>

<%= link_to 'Edit', edit_listing_path(@listing), class: "btn btn-link" %>
<%= link_to 'Back', listings_path, class: "btn btn-link" %>

在模型中，

class Listing < ActiveRecord::Base
  has_attached_file :image, :styles => { :medium => "200x", :thumb =>        "100x100>" }, :default_url => "default.jpg"
  validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/
end

在视图中，show.html.erb

<p id="notice"><%= notice %></p>

<div class="row">
   <div class="col-md-6">
     <div class="thumbnail">
      <%= image_tag @listing.image.url %>
    </div>
  </div>
  <div class="col-md-6">
    <h3><%= @listing.name %></h3>
    <p><%= number_to_currency (@listing.price) %></p>
    <p><%= @listing.description %></p>
  </div>
</div>

<%= link_to 'Edit', edit_listing_path(@listing), class: "btn btn-link" %>
<%= link_to 'Back', listings_path, class: "btn btn-link" %>

宝石安装，
