ErrorIndexer

Allows to index error messages on has many assoccitions.

Installation

Add this line to your application's Gemfile:

gem 'error_indexer', github: 'okosyk/error_indexer'

And then execute:

$ bundle

Usage

Just add index_errors: true to your has_many association.

Example:

class DoubleHamburger < ActiveRecord::Base
  has_many :patties, index_errors: true
  accepts_nested_attributes_for :patties
end

class Patty < ActiveRecord::Base
  MEAT_TYPES = [
    "beef",
    "chicken",
    "pork"
  ]

  belongs_to :double_hamburger
  validates :meat_type, :inclusion=> { :in => MEAT_TYPES }
end

In case of validation failures on nested assocciations error messagges will look like this:

{
  :"patties.0.meat_type" => ["is not included in the list"],
  :"patties.1.meat_type "=> ["is not included in the list"]
}
