boolean_attr_accessor
#5622
I'd like to propose adding a boolean_attr_accessor core extension to Module:
class Foo
boolean_attr_accessor :bar
end
foo = Foo.new
foo.bar = "1"
foo.bar? #=> true
I find myself needing this feature a lot, specifically when adding virtual boolean attributes to ActiveRecord models using them with form helpers in the view.
Patch attached with a rough version.
Thoughts?

Mark, I think you should also post on the core list: http://groups.google.com/group/rubyonrails-core You'll get more responses there as to whether this is a desired feature or not.

I use such code for this:
module Kernel def Boolean(b) return b if [FalseClass, TrueClass, NilClass].any?{|k| b.is_a?(k)} case b when /^1$/, /^true$/i , /^yes$/i then true when /^0$/, /^false$/i , /^no$/i then false else raise ArgumentError, "Unknown conversion to boolean type from: #{b.class}, Inspect: #{b.inspect}" end end end def bar=(value) write_attribute(:bar, Boolean(value)) end -
Gaston RamosI like the idea, but I'm not sure if it is right to take a lot of values as false

Aditya SanghiYou may want to make this a plugin first? If it's a really popular plugin, perhaps it will get included in the future.
