A way to add strong typing support to your ruby attributes.
Add this line to your application's Gemfile:
gem 'attr_typed'And then execute:
$ bundle
Or install it yourself as:
$ gem install attr_typed
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.
After checking out the repo, run bundle to install dependencies. Then, run rake spec to run the tests.
