Question

Lets take this example Model:

class Address < ActiveRecord::Base
  attr_accessible :city, :postcode, :street, :number
  validates :city, presence: true, size: {minimum: 2}
  validates :postcode, presence: true
  validates :street, presence: true 
  validates :number, presence: true  
end

Do i have to make all validations for each attribute separate? All attributes here have one common validation presence: true. Can´t I write something like validates * , presence: true

Hope you understand what I mean. There should be a solution, as rails and ruby often talk about the DRY way … 🙂

Answer 1

validates_presence_of :city, :street, :postcode, :number
