Question

我对rails非常陌生，我正在尝试设置我的rails应用程序以使用paperclip将多个图像上传到s3。

我做了什么：

environments/production.rb
config.paperclip_defaults = {
  :storage => :s3,
  :s3_credentials => {
    :bucket => ENV['S3_BUCKET_NAME'],
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
  }
}

在我的模型中：

has_attached_file :avatar,
styles: {
large: '640x480#',
medium: '300x300>',
thumb: '100x100#' 
}

# Validate the attached image is image/jpg, image/png, etc
validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/

我不确定此处包含哪些其他信息。但是我通过heroku上的指南来设置它。当我尝试上传图像时，我没有收到错误或heroku日志中的任何内容。它只是没有显示我的s3桶中的项目。

这是我从Heroku获得的日志：

如果我需要提供更多信息，请告诉我。我几天来一直在努力解决这个问题，我不知道发生了什么。

Answer 1

我搞定了！我将模型更改为以下内容并再次开始工作！我必须在某个时候编辑它并在has_attached_file之后输入错误的名称。

class Asset < ActiveRecord::Base
  belongs_to :project

  has_attached_file :asset,
  styles: {
    large: '640x480#',
    medium: '300x300>',
    thumb: '100x100#'
  },
  :path => ':class/:id/:style.:extension'

end

Answer 2

我使用paperclip上传多个文件。这是我在模型中的内容：

has_attached_file :avatar, 
    :styles => { :medium => "100x100>", :thumb => "50x50>" },
    :convert_options => { :thumb => "-quality 92", :medium => "-quality 92" },
    :storage => :s3,
    :bucket => 'media.mydomain.com',
    :s3_credentials => {
        :access_key_id => 'my_access_key',
        :secret_access_key => 'my_secret'
    },
    :path => ':class/:id/:style.:extension'

我的production.rb或任何其他配置文件中没有任何内容

如何设置paperclip将多个文件上传到s3
