Here is the question, I have a customer and address model as follows:

class Customer < ActiveRecord::Base
  has_one :address, as: :addressable
end

class Address < ActiveRecord::Base
  belongs_to :addressable, polymorphic: true
end

I have a customer form with the render address information, for example:

# customers/form   
  = f.input :name
  ...
  # render form/address
  = f.input :apto
  = f.input :city
  = f.input :references

What I am looking for is to validate the address fields in the customer form, in such a way that if the user does not enter any value then it prevents its creation or update

pdd: The address entity is polymorphic and I can use it in any relationship. But I don't know how to validate its fields when I use it in the form of other relations

If you could help me I would be grateful and thank you very much for taking the time to read me.

UPDATE 22/12/2022

I would like to specifically validate the address fields (apto, city, reference) that are in customers only and not in others entities

Since any other entity can use address and in those entities the fields must be without validation

many thanks to @max who recommended validates_associates, however it validates all addresses

Maybe you are looking for:

validate :validate_fields, if: -> { addressable_type == 'Customer' }
