Question

这是我最近遇到的问题的延续 - Stack Level Too Deep error - produced with strong parameters I think

每当我进行Post创建（涉及文件上传）时，我都会收到此错误：

Excon::Errors::SocketError - Broken pipe:

我的Post模型如下所示：

# == Schema Information
#
# Table name: posts
#
#  id         :integer          not null, primary key
#  status     :string(255)
#  title      :string(255)
#  date       :datetime
#  photo      :string(255)
#  body       :text
#  created_at :datetime
#  updated_at :datetime
#  user_id    :integer
#  ancestry   :string(255)
#  file       :string(255)
#

class Post < ActiveRecord::Base
  has_ancestry
  belongs_to :user
  resourcify

  mount_uploader :photo, ImageUploader
  mount_uploader :file, FileUploader
end

我的控制器看起来像这样：

  def create
    @post = current_user.posts.new(post_params)

    respond_to do |format|
      if @post.save
        format.html { redirect_to @post, notice: 'Post was successfully created.' }
        format.json { render :show, status: :created, location: @post }
      else
        format.html { render :new }
        format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  private
    # Never trust parameters from the scary internet, only allow the white list through.
    def post_params
      params.require(:post).permit(:status, :title, :date, :photo, :body, :parent_id)
    end

这是我的image_uploader.rb：

# encoding: utf-8

class ImageUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick
  storage :fog

  include CarrierWave::MimeTypes
  process :set_content_type

  def store_dir
    "images/#{model.id}-#{model.created_at}"
  end

  version :thumb do
    process :resize_to_fit => [80, 80]
  end

  version :large do
    process :resize_to_limit => [400, 400]
  end

  def extension_white_list
    %w(jpg jpeg gif png)
  end

end

这是我的Gemfile：

这是我的上传表单部分：

    <%= f.error_notification %>

    <%= f.input :parent_id, as: :hidden %>

    <% if can? :manage, @post %>
      <%= f.input :status, collection: Status.all %>
    <% end %>       

    <%= f.input :title %><br />
    <%= f.input :date %><br />      
    <%= f.input :photo %><br />
    <%= f.input :body %><br />      

  <%= f.button :submit %>

<% end %>

这是我的config/carrierwave.rb文件：

CarrierWave.configure do |config|
  config.fog_credentials = {
    provider:               'AWS',
    region:                 'us-east-1',                          
    aws_access_key_id:      ENV["AWS_ACCESS_KEY"],         
    aws_secret_access_key:  ENV["AWS_SECRET_ACCESS_KEY"],         
  }
  config.fog_directory  = ENV["AWS_MY_BUCKET"]       
end

可能导致此问题的任何想法？

这是一些更多的调试信息。删除图像大小后，Socket Error消息就会消失。

但这是我得到的新错误：

Answer 1

我认为它可能与语言环境有关。

这是一个使用s3的人的例子，但这是一个相同的想法。 they说出以下内容：

我最近在我的网站上工作，遇到了通过Carrierwave / Fog将更大的文件（如1.8M）上传到S3的问题。我收到以下错误：Excon :: Errors :: SocketError（Broken pipe（Errno :: EPIPE））：

我发现需要在我的carrierwave.rb初始化程序文件中设置区域代码才能上传更大的文件。显然它默认使用某个区域代码而不是我使用的区域代码，并且由于某种原因导致在上传较大文件时出错。

要查找区域代码，请在S3中导航到已存储的实际文件并单击它，然后单击屏幕右上角的“属性”。您将看到类似以下内容的链接：

https://s3-us-west-2.amazonaws.com/ginger2/uploads/web_developer_project_image/image/1/thumb_Screen_Shot_2013-09-05_at_2.10.45_PM.png

在这种情况下，以下是您应在配置中设置的区域代码：us-west-2

Answer 2

我明白了。发生了什么事我在AWS IAM中为这个应用程序创建了一个新用户，但我没有给该用户提供正确的凭据。即我从未创建安全策略或将其分配给组。所以它产生了403错误。

现在我已经解决了这个问题，一切顺利。

我希望这有助于其他人。
