Paperclip/S3的"缺少必需:桶选项"

Question

在我的Rails应用程序中,我让用户在创建"发布"时上传图像,并且应该直接上传到S3.我在开发和生产中都遇到以下错误.

编辑:我应该注意,尝试从表单提交上的发布编辑页面上传时会发生此错误.

ArgumentError in ReleasesController#update

missing required :bucket option
Rails.root: /Users/jasondemeuse/pressed

我以前做过这个没有使用过Carrierwave的问题,但是现在因为我正在使用Paperclip而无法弄清楚我做错了什么.我在SO和其他地方看到的所有修复都是heroku问题,但是我在开发时遇到了同样的问题而且没有一个修复有帮助.

这是相关代码("..."表示不相关的代码段):

development.rb

Appname::Application.configure do

...

  config.paperclip_defaults = {
    :storage => :s3,
    :s3_protocol => 'http',
    :s3_credentials => {
      :bucket => ENV['AWS_BUCKET'],
      :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
      :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    }
  }
end

production.rb

Appname::Application.configure do

...

  config.paperclip_defaults = {
    :storage => :s3,
    :s3_protocol => 'http',
    :s3_credentials => {
      :bucket => ENV['AWS_BUCKET'],
      :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
      :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    }
  }
end

release.rb

class Release < ActiveRecord::Base
  attr_accessible ... :banner


  belongs_to :user


  has_attached_file :banner, styles: {
    thumb: '100x100>',
    square: '200x200#',
    medium: '300x300>',
    spread: '1200x200'
  }

  has_many :banners, :dependent => :destroy
  accepts_nested_attributes_for :banners, :allow_destroy => true


end

show.html.erb

<%= image_tag @release.banner.url(:medium) %>
<%= @release.banner.url %>

// Have both of these in for now to see if they work, but since the upload isn't working it's giving me the missing.png

_form.html.erb

<%= f.label "Add A Banner?" %><br />
<%= f.file_field :banner %>

heroku config(在.bash_profile中用于开发)

AWS_ACCESS_KEY_ID:            XXXXXXXXXXXXXXXX
AWS_BUCKET:                   appname
AWS_SECRET_ACCESS_KEY:        XXXXXXXXXXXXXXXXXXXXXXXXXXX

编辑:这是我的控制器的相关部分

  def update
    @release = Release.find(params[:id])


    respond_to do |format|
      if @release.update_attributes(params[:release])
        format.html { redirect_to [@user,@release], notice: 'Release was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: "edit" }
        format.json { render json: @release.errors, status: :unprocessable_entity }
      end
    end
  end

我知道这应该是非常简单的,我确信我只是忘记了一些明显的东西,但我一直在讨论这个演练以及我发现的修复,似乎没有任何工作.是否有我忘了运行的rake任务或捆绑或什么？

先感谢您!

编辑2:以下答案帮助了我很多,切换到fog宝石修复了大多数东西给我.为了防止其他人遇到这些相同的问题,我也遇到了另一个让我感到困惑的问题.如果你有heroku问题和a Paperclip::PaperclipError (Item model missing required attr_accessor for 'image_file_name'):,请确保你运行heroku rake db:migrate然后重启heroku heroku restart.我加载了我的架构,错误地认为我不需要这样做.

可以在此处找到上述答案.

Answer 1

我认为这是因为:bucket应该是一个选项传递给Paperclip而不是S3.
固定配置

  config.paperclip_defaults = {
    :storage => :s3,
    :s3_protocol => 'http',
    :bucket => ENV['AWS_BUCKET'],
    :s3_credentials => {
      :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
      :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    }
  }

而Paperclip :: Storage :: S3 doc似乎也证实了,即使是如此糟糕的写入/格式化.

编辑:

在我的一个项目中,我使用Paperclip with Fog gem,这很有效

Paperclip::Attachment.default_options.merge!(
  :storage => :fog,
  :fog_credentials => {
    :provider => 'AWS',
    :aws_access_key_id => ENV['S3_ACCESS_KEY_ID'],
    :aws_secret_access_key => ENV['S3_SECRET_ACCESS_KEY'],
    :region => 'eu-west-1' # in case you need it
  },
  :fog_directory => ENV['S3_BUCKET'], # only one of those is needed but I don't remember which
  :bucket => ENV['S3_BUCKET']
)
