A shipment_type is a ruby object, you want to send a string.

If you are needing to import relationships, add methods on the Port model like so

class Port < ApplicationRecord

  def shipment_type_name
    shipment_type.try(:name)
  end

  def shipment_type_name=(name)
    self.shipment_type = ShipmentType.where(:name => name).first_or_create
  end

  def country_country_code
    country.try(:country_code)
  end

  def country_country_code=(code)
    self.country = Country.where(:country_code => code).first
  end


end

Then in the CSV you'd send a shipment_type_name and country_country_code attributes.

You would do something similar to other relationships.
