Rails - Mar 2008 - ActiveRecord::Base Collections

I have two entities (Department  and Project) that extends
ActiveRecord::Base. The department is mapped to have many projects. When
i make a query using the find(:all) (Department.find(:all)), i get a
collection of the departments with the attributes(id, project_id) of the
database. I would like to receive in each department one entity of the
project class.

I will appreciate any help


-----------------------------------------------------------------------
class Department < ActiveRecord::Base
   has_many :project
end

class Project < ActiveRecord::Base
end

Still not work. I changed my classes and the project is not comming 
inside of the department

I changed my classes to:
-------------------------------------------------------------------------------
class Department < ActiveRecord::Base
  has_one :project
end

class Project < ActiveRecord::Base
  belongs_to :department
end
