Instructions
Allow you to easily specify default values for attributes on new model objects. Eg:
class Person < ActiveRecord::Base
defaults :country => 'New Zealand', :type => 'Unknown'
default :last_name do |person|
person.first_name
end
end
You can also define a defaults method like so:
class Person < ActiveRecord::Base
def defaults
self.first_name = "Jonathan"
end
end
The default value is only used if the attribute is not present in the attributes hash:
p = Person.new p.country # "New Zealand" p = Person.new(:country => nil) p.country # nil
Installation

Nice and neat, thanks!
The svn repository appears down as of 2007-07-24.
Thanks! - Much nicer than the alternatives :)
Just what I was looking for! Cheers!
No, you can only specify static default values with migrations. This plugin allows the default values to be determined when a new model object is created, allowing for features like user-configurable defaults.
> Doesn't ActiveRecord already do this based on the defaults set in the database?
