Setting booleans in AR

arbooleans.rb

# When params come back from a form, checked boxes come back as 'field_name' => "on". 
# So we can use that to update attributes, right?
model.field_name # => false
model.update_attribute(:field_name, "on")
model.field_name # => false

# WTF?

Also,

>> model.update_attribute :boolean, "true"
=> true
>> model.boolean
=> true

So it turns out that the jQuery default value for checked boxes is "on".

The list of values ActiveRecord considers "truthy" for setting boolean attributes is: [true, 1, '1', 't', 'T', 'true', 'TRUE']
