LocationsController#create 中的 AWS::Errors::MissingCredentialsError 使用回形针和 aws Gem

Question

我在使用回形针和 AWS gem 的 LocationsController#create 中收到以下错误AWS::Errors::MissingCredentialsError

有关异常的更多详细信息：

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

感谢您花时间查看此内容

它显然没有找到您的 S3 凭据。我在 Paperclip 文档中找不到任何地方说您应该在应用程序配置中指定您的 S3 凭据。

一般来说，您可以将其放入模型中，如下所述：
