Ruby on rails AWS:：Errors:：丢失凭证位置错误控制器#使用回形针和AWS Gem创建

我在LocationsController#使用回形针和AWS gem创建时遇到以下错误AWS:：Errors:：MissingCredentialsError

有关例外情况的更多详细信息：

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 * 

我目前正在我的机器上的开发环境中运行此代码，这里是development.rb

  Gmaps::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Log error messages when you accidentally call methods on nil.
  config.whiny_nils = true

  # Show full error reports and disable caching
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger
  config.active_support.deprecation = :log

  # Only use best-standards-support built into browsers
  config.action_dispatch.best_standards_support = :builtin

  # Raise exception on mass assignment protection for Active Record models
  config.active_record.mass_assignment_sanitizer = :strict

  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  config.active_record.auto_explain_threshold_in_seconds = 0.5

  # Do not compress assets
  config.assets.compress = false

  # Expands the lines which load the assets
  config.assets.debug = true

  # Amazon S3 settings for Paperclip uploads
Paperclip::Attachment.default_options.merge!({  
storage: :s3 ,
s3_credentials: {
  access_key_id:  ENV['key_id'],
  secret_access_key:  ENV['key'],
    bucket:  "#{ENV['bucket']}-#{Rails.env}"
    },
    url: ":s3_domain_url",
   path: "/:class/:attachment/:id_partition/:style/:filename"
    })
end

这是我的模型

class Location < ActiveRecord::Base
    geocoded_by :address
    after_validation :geocode

      has_attached_file :picture,
        :styles => { :medium => "300x300>", :thumb => "100x100>" }
end

类位置{:medium=>“300x300>”，：thumb=>“100x100>”}
结束

感谢您花时间查看此

它显然找不到您的S3凭据。我在回形针文档中找不到任何地方，上面说应该在应用程序配置中指定S3凭据

通常，您可以将其放入如下所述的模型中：

与此相关的几个线程可能会有所帮助：

尝试只使用AWS Gem 我希望您尝试仅使用AWS Gem配置，并查看凭据是否有效：

config/initializers/aws.rb 然后打开控制台并尝试以下操作：

bundle exec rails c
S3.objects.first

输出是什么

基本上，先让这项工作开始，然后再处理回形针宝石的抽象。

我的解决办法是重新排列宝石在gemfile中的顺序：

gem'aws sdk'

必须在

gem'paperclip'之前

这个：

gem 'aws-sdk'
gem 'paperclip'

gem 'paperclip'
gem 'aws-sdk'

不是这个：

gem 'aws-sdk'
gem 'paperclip'

gem 'paperclip'
gem 'aws-sdk'

幸运地发现了这一点。
感谢您的关注。我尝试了上面的链接，但没有任何运气。看起来他们都在做同样的事情。我确实在没有任何LuckId的情况下尝试了上述建议。您是否尝试将凭据设置为en环境变量？就像这里一样：我想如果没有luckI想要添加的任何新sdk，您将不得不使用Aws.config.update（{}），因为config不再是一种方法，而是一种散列。我觉得更奇怪的是，首选的方法应该是在模型中添加creds。这与模型无关，如果您在多个模型中进行上传，会怎么样？
