EasyParams

Installation

Add this line to your application's Gemfile:

gem 'easy_params'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install easy_params

Usage

# app/params/api/v2/icqa/move_params.rb
class Api::V1::Carts::MoveParams < EasyParams::Base
  attribute :receive_cart_id, integer
  attribute :i_am_sure, bool
  attribute :location_code, string.default('')
  attribute :sections, struct do
    attribute :from, string
    attribute :to, string
  end
  attribute :options, array.of(struct) do
    attribute :option_type_count, integer
    attribute :option_type_value, integer

    validates :option_type_count, :option_type_value, presence: { message: "can't be blank" }
  end

  validates :receive_cart_id, :location_code, presence: { message: "can't be blank" }
end

Validation messages for nested attributes will look like this.

{
  :"sections/0/id"=>an_instance_of(Array),
  :"sections/0/post/id"=>an_instance_of(Array),
  :"post/id"=>an_instance_of(Array),
  :"post/sections/0/id"=>an_instance_of(Array)
 }

Optionally you can use more compact form

class MyParams < EasyParams::Base
  extend EasyParams::DSL

  quantity integer.default(1)
  posts each do
    content string.default('')
  end
  user has do
    role string
  end
end
