PostsController#create 中的 Excon::Errors::SocketError

Question

我正在使用 Rails 建立一个照片博客，但遇到了这个错误：Excon::Errors::SocketError in PostsController#create

对等方重置连接 (Errno::ECONNRESET)

提取的源代码（第 30 行附近）：

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


(0.2ms)  BEGIN
  SQL (0.3ms)  INSERT INTO "posts" ("title", "image", "description", "created_at", "updated_at") VALUES ($1, $2, $3, $4, $5) RETURNING "id"  [["title", "Title test"], ["image", "mcm-magnavox-stereo-1.jpg"], ["description", "Description test"], ["created_at", "2016-02-19 22:13:34.023935"], ["updated_at", "2016-02-19 22:13:34.023935"]]
   (0.9ms)  ROLLBACK

Excon::Errors::SocketError (Connection reset by peer (Errno::ECONNRESET)):
  app/controllers/posts_controller.rb:30:in `block in create'
  app/controllers/posts_controller.rb:29:in `create'

这是我的帖子模型：

class Post < ActiveRecord::Base
    validates_presence_of :title, :image

    mount_uploader :image, PhotoUploader
end

这是我的后期控制器：

class PostsController < ApplicationController
  before_action :set_post, only: [:show, :edit, :update, :destroy]

  # GET /posts
  # GET /posts.json
  def index
    @posts = Post.all
  end

  # GET /posts/1
  # GET /posts/1.json
  def show
  end

  # GET /posts/new
  def new
    @post = Post.new
  end

  # GET /posts/1/edit
  def edit
  end

  # POST /posts
  # POST /posts.json
  def create
    @post = Post.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

  # PATCH/PUT /posts/1
  # PATCH/PUT /posts/1.json
  def update
    respond_to do |format|
      if @post.update(post_params)
        format.html { redirect_to @post, notice: 'Post was successfully updated.' }
        format.json { render :show, status: :ok, location: @post }
      else
        format.html { render :edit }
        format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /posts/1
  # DELETE /posts/1.json
  def destroy
    @post.destroy
    respond_to do |format|
      format.html { redirect_to posts_url, notice: 'Post was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_post
      @post = Post.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def post_params
      params.require(:post).permit(:title, :image, :description)
    end
end

CarrierWave.configure do |config|
  config.fog_credentials = {

我的地区没有价值。我首先设置 us-west-1 并返回错误，但将区域更改为 us-east-1 有效。 谢谢吉姆斯！
