红宝石回形针到s3错误

问题描述

我正在尝试在heroku和s3上使用回形针，但是我有很多可以与照片关联的表，例如，我们将使用：review。 我正在尝试将照片与评论分开，然后分别上传，但是由于我是红宝石的新手，所以我认为我失败了。 我已经安装并捆绑了“ aws-s3 \” gem。 这是我得到的错误：

LoadError in ReviewsController#create

no such file to load -- aws/s3 (You may need to install the aws-s3 gem)
Rails.root: C:/www/devise

Application Trace | Framework Trace | Full Trace

This error occurred while loading the following files:
   aws/s3

照片型号：

class Photo < ActiveRecord::Base
        belongs_to :user
        belongs_to :shop
        belongs_to :baristum
        belongs_to :review

      #paperclip
      has_attached_file :photo,:styles => {
           :thumb=> \"100x100#\",:small  => \"400x400>\",:original => \"800x800\" },:storage => :s3,:s3_credentials => \"#{RAILS_ROOT}/config/s3.yml\",:path => \"/:style/:id/:filename\"

    end

照片模式：

t.string   \"file_name\"
    t.string   \"content_type\"
    t.integer  \"file_size\"
    t.integer  \"user_id\"
    t.integer  \"barista_id\"
    t.integer  \"review_id\"
    t.integer  \"shop_id\"
    t.datetime \"created_at\"
    t.datetime \"updated_at\"

审核控制器：

def create
    #add the current user to the review hash,from the session var.
    params[:review][:user_id] = current_user.id

    #move the photo to another var,so I can remove it from the review insert
    @photoUpload = params[:review][:photo]
    params[:review].delete(\"photo\")

    @review = Review.new(params[:review])

    respond_to do |format|
      if @review.save
        @photo = Photo.new(:photo => @photoUpload,:review_id => @review.id)
        @photo.save

        format.html { redirect_to(@review,:notice => \'Review was successfully created.\') }
        format.xml  { render :xml => @review,:status => :created,:location => @review }
      else
        @shopList = Shop.find(:all)
        format.html { render :action => \"new\" }
        format.xml  { render :xml => @review.errors,:status => :unprocessable_entity }
      end
    end
  end

解决方法

        当您在gem文件中包含\'aws-s3 \'gem时，请记住添加require语句。

gem \'aws-s3\',:require => \'aws/s3\'

    ,        当前版本的Paperclip使用

aws-sdk

宝石，而不是

aws-s3

宝石。 尝试运行该gem的最新版本，并与支持您的Rails堆栈的Paperclip的最新版本（适用于Rails 2.3的Paperclip 2.x或适用于Rails 3+的Paperclip 3.x）结合使用。     ,        看起来您需要在照片架构中包含以下字段。

  t.string :file_file_name
  t.string :file_content_type
  t.integer :file_file_size
  t.datetime :file_updated_at

运行此命令将生成一个迁移，供您执行

  #this convention: rails generate paperclip [model] [attachmentname]
  rails generate paperclip photo file

对于回形针，您必须具有遵循此约定命名的表列才能使用它们：\'attachmentname \'_ file_name，\'attachmentname \'_ content_type等...在其中调用Photo模型的has_attachment \ “文件\”。
