ComponentValidations

This repo is an experiment and strays from the standard Rails way.

A useful strategy for building multi-model forms in Rails is to use a form object which composes other model objects. This is well described on the Code Climate Blog. One barrier to this strategy is validating the form object without duplicating the validation logic already described by component models. component_validations is an attempt to remove this barrier by mapping ActiveModel object attributes to their component models and delegating all validations without using validates_associated or accepts_nested_attributes.

Usage

class Signup
  include ActiveModel::Validations

  validates_component Account, :name => :account_name, :subdomain => :account_subdomain
  validates_component User, {
    :name => :name,
    :email => :email,
    :password => :password,
    :password_confirmation => :password_confirmation
  }

  # ...
end
