class Job < ActiveRecord::Base
  include NearbyMethods
end

module NearbyMethods
  include ActiveSupport::Concern

  def nearby(asset, radius=10)
    asset.singularize.constantize.find_near(self.latlng, radius) # forget nearby and do a radius search
  end
end

So you can do:

Job.first.nearby(:jobs)

or 

@company.nearby(:companies)

or

@job.nearby(:companies)

Why not Company.near(Job.first)?
