The validate method is used along with a custom validator method. The validates method is "built in" and uses a DSL to specify how you want the validations to work. validate :has_a_bow_on_top? private def has_a_bow_on_top? unless bow&.on_top? errors[:bow].add "must be on top" false end end The built-in validates method is configured like this: validates :bow, presence: true This is a very basic example, there are lots more things you can do with it.
