Is it possible to pass :symbols to the valid? method so that I can define if the object is valid up to a certain point?

Eg. if I have an object Person and want to call Person.valid?(:basic_info) and it will return true only if a certain subset of fields (say name & gender) are present?

I saw something that I thought might be of use but cannot get it working, it’s conditional validations http://guides.rubyonrails.org/active_record_validations_callbacks.html#conditional-validation , in particular grouping conditional validations, but I couldn’t get it working…

Can anyone help me out here please…

    I got this to work using conditional validations, so now i can use .valid?(:basic) say for when i only want to check that the person has a name with the call…

    validates_presence_of :name, :when => [:basic]

    Documentation here: http://apidock.com/rails/ActiveRecord/Validations/valid%3F

    This way I can have the object return true when calling .valid? even when it doesn’t have a name, good times…
