module ModelX::Boolean
Adds boolean attribute accessors to any object, allowing boolean-ish values to be set as well.
Usage¶ ↑
class MyObject include ModelX::Boolean attr_accessor :my_attribute boolean :my_attribute end
Now, the following can be used:
object = MyObject.new object.my_attribute = false object.my_attribute? # => false object.my_attribute = '0' object.my_attribute? # => false object.my_attribute = '1' object.my_attribute? # => true object.my_attribute = 'false' object.my_attribute? # => false
Note that an existing attribute writer must exist.
The values '0', 0, 'off', 'no' and 'false', and all values that Ruby considers false are deemed to be false. All other values are true.
