Initialize won't work??

I've got a simple model

class ExtraType < ActiveRecord::Base   has_many :match_balls   attr_accessor :extra_total   def initialize     self.extra_total=0   end end

When I try ex=ExtraType.new, I get INTERNAL ERROR!!! You have a nil object when you didn't expect it! The error occurred while evaluating nil.has_key? /Library/Ruby/Gems/1.8/gems/activerecord-2.2.2/lib/active_record/ base.rb:2633:in `has_attribute?'

I don't think I'm doing anything daft here .. or am I (It's the end of a long week after all) Ruby 1.8.6 with Rails 2.2.2

I think you should call super in initialize otherwise it is not doing the base class initialize. Also watch out as I think rails does not always call new to instantiate an object so your initialize may not get called. See

for example.

Many thanks. Calling super fixed it. Doh - should have realised that - as I said - end of a long week.
