while using after_create (ArgumentError: You need to supply at least one validation)

I am trying to create a record in ClientUserEmailPreference when an email record is newly created. I tried after_create to create a new record whenever new email record is created. But, When I try to create a new email record, it shows ArgumentError: You need to supply at least one validation The following is my email model.

class Email < ApplicationRecord
    belongs_to :email_type
    belongs_to :email_preference_section
    has_many :client_user_email_preferences
    validates :name, allow_blank: false, presence: true
    validates :email_type_id, allow_blank: false, presence: true
    validates :email_preference_section_id, allow_blank: true
    validates :position, allow_blank: false, presence: true

    after_create :set_default_to_client_users

    def set_default_to_client_users
            new_preference = ClientUserEmailPreference.new
            new_preference.client_user_id = that_client_user.id
            new_preference.email_id = self.id
            new_preference.enabled = true
            if self.email_type_id != 1
                new_preference.frequency = "every week"
                new_preference.day_of_the_week = 1
            end
            new_preference.save
    end
end

I don't know how to effectively create a row in ClientUserEmailPreference whenever a new email is created

The error is probably at this line

validates :email_preference_section, allow_blank: true

Since it's an association, if you want it be optional remove the above validation and then do this instead

belongs_to :email_preference_section, optional: true

Also, you don't need this line too since it is enabled by default for foreign keys

validates :email_type_id, allow_blank: false, presence: true

Give it a try!
