How do I make a method available to both my controller and model in Rails?

Question

I have a private method in my Rails app to connect to Amazon S3, execute a passed block of code, then close the connection to S3. It looks like so;

def S3
  AWS:         


        

Answer 1

You can write a module as :

module MyModule
  def self.S3(args*)
    AWS::S3::Base.establish_connection!(
      :access_key_id     => 'Not telling',
      :secret_access_key => 'Really not telling'
    )
    data = yield
    AWS::S3::Base.disconnect
    data
  end
end

and then call it in your controller or model as

MyModule.S3(params*)
