Rails Ancestry can't get capital

Question

I am using ancestry gem in rails 6 on my Location model. On the model, I have a location_type enum.

class Location < ApplicationRecord

    enum location_type: ["continent", "country", "state", "state_capital", "country_and_state_capital", "city" ]

when a record has a location type of country I would like to find its "country_and_state_capital" as its country_capital in the location model

def country_capital
   self.descendants.where(location_type: "country_and_state_capital")
end

and then call its data in the view

currently when I do this it just shows location

Location Load (0.3ms)  SELECT "locations".* FROM "locations" WHERE "locations"."id" = $1 LIMIT $2  [["id", 3], ["LIMIT", 1]]
  ↳ app/views/locations/show.html.erb:25

any idea what I can do to just access the one record
