问题描述

我想上传图片在AWS。

I am trying to upload image at aws.

class Asset < ActiveRecord::Base
  belongs_to :post
  attr_accessible :image
  has_attached_file :image, :styles => { :medium => "640x480>",
                                     :thumb => "100x100#"},
  :storage => :s3,
   :s3_credentials => "#{Rails.root}/config/s3.yml",
  :path => ":attachment/:id/:style.:extension",
  :bucket => 'yourbucket'
end

s3.yml

development:
  access_key_id: xxxxxxxx

   secret_code: xxxxx

我得到一个消息

I am getting a message

 AWS::Errors::MissingCredentialsError in PostsController#create

Missing Credentials.

 Unable to find AWS credentials.  You can configure your AWS credentials
 a few different ways:

 * Call AWS.config with :access_key_id and :secret_access_key

 * Export AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY to ENV

* On EC2 you can run instances with an IAM instance profile and credentials
 will be auto loaded from the instance metadata service on those
  instances.

* Call AWS.config with :credential_provider.  A credential provider should
either include AWS::Core::CredentialProviders::Provider or respond to
the same public methods.

= Ruby on Rails

在一个Ruby on Rails应用程序，你也可以指定你的凭据通过以下方式：

In a Ruby on Rails application you may also specify your credentials in the following ways:

通过一个配置的初始化脚本中使用任何上述方法（如RAILS_ROOT /配置/初始化/ AWS-sdk.rb）。

Via a config initializer script using any of the methods mentioned above(e.g. RAILS_ROOT/config/initializers/aws-sdk.rb).

通过位于RAILS_ROOT /配置/ aws.yml一个YAML配置文件。这个文件应该被格式化，如默认RAILS_ROOT /配置/ database.yml中文件。

Via a yaml configuration file located at RAILS_ROOT/config/aws.yml.This file should be formated like the default RAILS_ROOT/config/database.ymlfile.

我相信我做的最后一步。

I believe I am doing the last step.

的Gemfile

gem 'rails', '3.1.3'
gem 'mysql'
gem 'koala'
gem 'paperclip'
gem 'aws-s3'
gem 'aws-sdk'

pciated任何帮助AP $ P $

Any help appreciated

推荐答案

对我下面的工作：

创建你的初始化名为aws.rb文件
将在你的aws.rb文件中的以下内容：

Create a file in your initializers called aws.rb
Put in the following in your aws.rb file:

AWS.config(
access_key_id: 'your_access_key',
secret_access_key: 'your_secret_access_key')

然后我的曲别针的选择是这样的：

Then my paperclip options looks like this:

has_attached_file :photo, :styles => { :medium => "300x300>", :thumb => "100x100>" },
:default_url => "missing_:style.png", :default_url => 'missing_:style.png', :storage =>
:s3, :bucket => "<my_bucket>"
