I noted that there was a potential for naming conflicts with the klass
name used by active scaffold so I have renamed my system to use
school_class rather than klass.
Here is the associations for school_class:
has_many :funds
has_many :mailings
has_many :students
has_many :teachers,
:class_name => "Staff",
:conditions => "staffs.role = 'teacher'"
has_many :ias,
:class_name => "Staff",
:conditions => "staffs.role = 'ia'"
belongs_to :first_contact,
:foreign_key => :first_contact_id,
:class_name => "User"
:conditions => "users.role = 'classco'"
belongs_to :second_contact,
:foreign_key => :second_contact_id,
:class_name => "User"
:conditions => "users.role = 'classco'"
The associated models have their required has_many/belongs_to.
I found an older version of AS that I has used in another project, and
just for the heck of it tried it too see if this might be a problem
with the latest version of AS.
And it happens to be an issue with the latest version of AS. My older
version from September seems to be doing just fine with all my
associations, HABTM's etc etc.
How can I help getting the latest version of AS fixed ?
under Rails 2.3.5 and using the HEAD version of AS I see one of two
errors:

There are no models, controllers, helpers, views, library & test
references to a Klass model. Neither is there any klass fields in the
database nor in db/schema.rb.
