Predicates
Predicates are truth accessors for your Ruby classes and models. Yep, that's about it.
Usage
Extend your class or model with Predicates and define the predicate by supplying an attribute:
require 'predicates'
class User
extend Predicates
attr_accessor :confirmed
predicate :confirmed?
end
user = User.new
user.confirmed = 1
user.confirmed? #=> true
Predicates will also create an attribute writer for you using attr_writer if the attribute you supplied has not been predefined.
class User
extend Predicates
predicate :confirmed?
end
user = User.new
user.confirmed = 1
user.confirmed? #=> true
Installation
Add this line to your application's Gemfile:
gem 'predicates'
And then execute:
$ bundle
Or install it yourself as:
$ gem install predicates
