ShadowForm

Fat model with validation on all cases always causes problems in the future. So my solution is ShadowForm. Now you can have your original model without validation and use form when you need it.

Installation

Add this line to your application's Gemfile:

gem 'shadow_form'

And then execute:

$ bundle

Or install it yourself as:

$ gem install shadow_form

How it works

You have your active_record or active_model model:

class User
  include ActiveModel::Model
  attr_accessor :name, :email, :password
end

And for example register form

class UserRegistrationForm < ShadowForm::Core
  shadow_of User
  give_name 'RegisterForm` # optional
  validation do
    validates :email, presence: true
    validates :password, presence: true
  end
end

And now you have UserRegistrationForm like User + Validation
