AttrTyped

A way to add strong typing support to your ruby attributes.

Installation

Add this line to your application's Gemfile:

gem 'attr_typed'

And then execute:

$ bundle

Or install it yourself as:

$ gem install attr_typed

Usage

Include the AttrTyped module in your class then declare your types like this:

  attr_typed name: :string,
             amount: :money,
             created_at: :time

The currently supported types are:

:string, :money, :time, :big_decimal, :date, :integer, :boolean, :date_time

The parsing behaves in a very predictable way, the only exception is when parsing a string of "y" (i.e. yes) to a boolean it will be true.

If you want to log parsing failures, use AttrTyped.logger = MyLogger.

If you want to use :time parsing you need to use ActiveSupport and have a default time zone setup.
