Rails - Nov 2007 - has_many :through problem

I''m building a simple support ticket system for use in our office. 
I''ve
got a model called Ticket and one called Category and I''m trying to set
it up so that I can add categories at will and assign many categories to
a single ticket.

I''m trying to use the has_many :through association to accomplish this,
but I''ve run into an issue.

Here''s the basic setup:

class Ticket < ActiveRecord::Base
  has_many :categoryassociations
  has_many :categories, :through => :categoryassociations
end

class CategoryAssociation < ActiveRecord::Base
  has_many :tickets

end

class Category < ActiveRecord::Base
  has_many :categoryassociations
  has_many :tickets, :through => :categoryassociations
end

I''m now receiving an error "uninitialized constant
Ticket::Categoryassociation."

I should be able to use @ticket.categories in the view to spit out the
associated categories, correct?  Does this all look like it should work?

if you say :categoryassociations, rails assumes your model is  
Categoryassociation. You need :category_associations for it to look  
for CategoryAssociation

this is missing a belongs_to :category.
