You can change data in as_json method, while data is hash:

class Profile
  include Mongoid::Document
  field :name, type: String

   def as_json(*args)
    res = super
    res["id"] = res.delete("_id").to_s
    res
  end
end

p = Profile.new
p.to_json

result:

{
    "id": "536268a06d2d7019ba000000",
    ...
}
