Generate random values

Question

I want to generate random name using the following code:

def random_card_holder
  Faker::Name.first_name + " " + Faker::Name.last_name
end

But I get validation error. Is this code valid?

Answer 1

Is this code valid?

Yes this is a valid code.

But I get validation error.

You validate the (assumably) card_holder column, and the result of this valid code does not meet the validation rules.
