Rails Models: Does the order of has_many, validation rules matter?

Question

Curious about Rails models - in Hartl's Rails Tutorial, he has a User model that includes the following has_many :microposts attr_accessor :remember_token, :activation_token, :reset_token before_save :downcase_email before_create :create_activation_digest has_secure_password

My question is - does the order you put these in matter?

No not all. You can declare these in anyone set of your choice.

I think that it is not necessary that validations follow any specific order. But you should keep your every validation flexible so that even if presence/length validation fails on any parameter, manipulation over it doesn't throw an error.
