How to set up AWS credentials in rails for development?

Question

I'm trying to figure out what is the best way to set up my credentials during development? I can set up production credentials due to heroku configuration variables ... but you need help if you are just testing the application locally.

I have it in my development.rb

config.paperclip_defaults = {
  :storage => :s3,
  :s3_credentials => {
    :bucket => ENV['BUCKET_NAME'],
    :access_key_id => ENV['ACCESS_KEY_ID'],
    :secret_access_key => ENV['SECRET_ACCESS_KEY']
  }
}  

But I'm not sure how to reference these ENV variables?

I created this aws.ymlfile in my / config folder

development:
  BUCKET_NAME: "somename"
  ACCESS_KEY_ID: "4205823951412980"
  SECRET_ACCESS_KEY: "123141ABNCEFEHUDSL2309489850"

I thought that if I matched the name ENV, would this work? This is probably not the case ...

I included aws.ymlin my .ignorefile

/config/aws.yml

dotenv gem. gem 'dotenv-rails', :groups => [:development, :test], `.env ' .

config.yml ./config.

./config/application.rb ,

config.before_initialize do
  dev = File.join(Rails.root, 'config', 'config.yml')
  YAML.load(File.open(dev)).each do |key,value|
    ENV[key.to_s] = value
  end if File.exists?(dev)
end

./config/config.yml

BUCKET_NAME: "somename"
ACCESS_KEY_ID: "4205823951412980"
SECRET_ACCESS_KEY: "123141ABNCEFEHUDSL2309489850"

If all else fails, you can simply start the rails application with command line options. It’s good to know the base case, where you know for sure that your parameters are really passed to your application:

ACCESS_KEY_ID = ABCDEFG SECRET_ACCESS_KEY = secreTaccessKey BUCKET_NAME = dev-images rails s

I prefer to set an alias in env:

alias railss = 'ACCESS_KEY_ID = ABCDEFG SECRET_ACCESS_KEY = secreTaccessKey BUCKET_NAME = dev-images rails s'
