Rails - Aug 2006 - what did I do to my app? (Superclass mismatch?)

It was working before (as far as I can tell), but I freezed_edge and 
now...

The first time I load this page, it works fine, the second time I get 
the superclass mismatch, the third time (and any subsequent times ) i 
get undefined method.

I think this means my class is getting loaded twice?

my model looks like this:

class Quotation < ActiveRecord::Base
  has_many :price_breaks
  has_many :items, :through => :price_breaks
  belongs_to :contact
end

#STI
class Cost < Quotation
end

class Price < Quotation
end


here''s what the third error says:
undefined method `contact'' for #<Cost:0xb7936bc8>

Cost.contact works in the console...

contact would be available to instances of Cost, so:

my_cost = Cost.new
my_cost.contact

that should work.

I just reverted back to revision 4720 and it works like normal again. I 
saw something about double loading errors in changeset 4730. Is this 
something I should make a ticket about? I don''t know enough rails to 
know if something is broken, or if I''m doing something wrong.

can we see your console output because Cost.contact should throw a
NoMethodError exception.

contact is a instance method, not a class method.

example:

class Project < ActiveRecord::Base
  has_many :tickets
end

class Ticket < ActiveRecord::base
  belongs_to :project
end
>> Ticket.project
NoMethodError: undefined method `project'' for Ticket:Class
        from
/usr/local/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/base.rb:1129:in
`method_missing''
        from (irb):1
>> t = Ticket.new
=> #<Ticket:0x257c6e8 @attributes={"created_on"=>nil,
"project_id"=>nil, "title"=>nil},
@new_record=true>
>> t.project
=> nil

sorry, i mean to say instances of Cost work in the console.

c = Cost.find :first
c.contact

works

speaking of the console, how do you make it load your subclass models 
when it first starts?

Loading development environment.
>> Cost
NameError: uninitialized constant Cost
>> Quotation
=> Quotation
>> Cost
=> Cost

Loading development environment.
>> FooTicket
=> FooTicket
>> Ticket
=> Ticket

where

class FooTicket < Ticket
end


no problems here.  then again, i''m not running edge either.
