Ruby on rails Access a file from a controller

If I am going about this wrong please let me know I can change it. I have a file in config/initializers/payload_signer.rb. I am trying to use this file in the controller that is called device_enrollment_controller.rb.

PayloadSigner.sign(get_profile)

get_profile is a method in the controller that gets the file I need and returns it. PayloadSigner references the other file. When I try to run this (keeping in mind im sure changes will have to be made in payload_signer for it work right) the error I get is uninitialized constant DeviceEnrollmentController::PayloadSigner. This leads me to believe I am referencing the payload_signer.rb file incorrectly. I have tried things like include and load but so far they are not working.

Any help or guidance is appreciated.

Rails Initializers are called before Controllers or Models. So it won't work. Initializers are not intended for this kind of use. Instead I suggest placing your code in a controller before_filter. Either in the ApplicationController or only in those controllers that require it (e.g. DeviceEnrollmentController). Something like this:

class DeviceEnrollmentController # Or ApplicationController

  before_filter :sign_payload

  protected

  def get_profile
    # Magic
  end

  def sign_payload
    PayloadSigner.sign(get_profile)
  end
end

EDIT: Another example:

class DeviceEnrollmentController

  # The filter is only applied to the sign action
  # (that's what the :only parameter does).
  before_filter :sign_payload, :only => [:sign]

  # Browsing to /show, you render this magic button of yours.
  def show
    # Render page that holds the button
  end

  # The magic button is bound to the /sign route.
  # Clicking on the button calls this action.
  def sign
    # When you get here, the #sign_payload method
    # has already been called.
  end

  protected

  def get_profile
    # Magic
  end

  def sign_payload
    PayloadSigner.sign(get_profile)
  end
end
