I was seeing these examples in a book: Person.minimum(:age).where('last_name <> ?', 'Drake') Person.minimum(:age).having('min(age) > 17').group(:last_name) The thing is minimum is returning a FixNum. When invoking the relation methods (e.g. where, having) on a fixnum will raise an exception: undefined method `where' for 1:Fixnum So am I missing something here?
invoking an activerecord relation method on the result of a calculation method, which returns a FixN
