How to structure a Ruby on Rails model? -


in our app's user model, have:

attr_accessor :remember_token, :activation_token, :reset_token   before_save   :downcase_email   before_create :create_activation_digest     before_save { self.email = email.downcase }     validates :first_name, presence: true, length: { maximum: 50 }     validates :last_name, presence: true, length: { maximum: 50 }     valid_email_regex = /\a[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i     validates :email, presence: true, length: { maximum: 255 },                         format: { with: valid_email_regex },                         uniqueness: { case_sensitive: false }     has_secure_password     validates :password, presence: true, length: { minimum: 6 }, allow_nil: true

now, need add relationship associations model, namely:

has_many :roles, dependent: :destroy has_many :agendas, through: :roles

does matter whether include latter go before or after former, in model?

if so, recommended / preferred / best way?

it doesn't matter, important thing consistent. usual best practice first can declare class' structure, before in operational details. example: 

class user < activerecord::base   attr_accessor :remember_token, :activation_token, :reset_token    has_many :roles, dependent: :destroy   has_many :agendas, through: :roles    before_save   :downcase_email   before_create :create_activation_digest   before_save { self.email = email.downcase }   validates :first_name, presence: true, length: { maximum: 50 }   validates :last_name, presence: true, length: { maximum: 50 }   valid_email_regex = /\a[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/   validates :email, presence: true, length: { maximum: 255 },                     format: { with: valid_email_regex },                     uniqueness: { case_sensitive: false }   has_secure_password   validates :password, presence: true, length: { minimum: 6 }, allow_nil: true end

again, 1 way things, it's common amongst rails applications.
