How to return nil when no image is present in paperclip?

I have one model that is 

class Retailer < ActiveRecord::Base
  ...
    has_attached_file :onboarding_image
  ...
end

If the onboarding_image is not present, when doing retailer.onboarding_image_url i'm getting: "/onboarding_images/original/missing.png"

Is there a config to get nil when no image is present? i know that i can do something like

retailer.onboarding_image.present? ? retailer.onboarding_image : nil but that is not the approach i want to follow, cause i have thousand of attached_files in all of my code.

if you have this attached files on multiple models, you can create concern for all classes that have has_attached_file :

module BoardUrl
  def board_url
    onboarding_image.present? ? onboarding_image.url : nil
  end
end

class Retailer
  include BoardUrl
end

This way you can use your board_url method on any model you need.

You can set the default_url as outlined here:

 has_attached_file :onboarding_image, default_url: ''

Another approach is to override the onboarding_image_url method:

  def onboarding_image_url(default_value=nil)
    onboarding_image.present? ? onboarding_image.url : default_value
  end
