Validates with :if

Question

I\'m trying to create a condition in which the attribute \'one\' is zero and the attribute \'two\' is one, then a model is not valid. But when I make:

Model.         


        

Answer 1

I think you have an error in your syntax:

validates :one, :two, :presence => true, :if => :condition_testing?

def condition_testing?
    !(one == 0 && two == 1)
end

There was one :if too many in there... And if I understand correctly you want to have it only validate in case one == 0 && two == 1? Then you condition_testing? is inverted (leave out the !())

If unsure you could try to use pry and insert a breakpoint into your condition_testing? method to see what's going on.

(Please note added ":" before condition testing)
