What is this line all about?
db.t_user_has_companies.first_name.requires=IS_NOT_IN_DB(db(db.t_user_has_companies.f_coname==request.vars.f_coname),db.t_user_has_companies.first_name)
Also, these lines in your t_user_has_companies table def don't match what
you say about them.
>>> Field('first_name', 'reference auth_user', label='User',
writable=True, readable=True, notnull=True, required=True, ondelete='NO
ACTION', requires=IS_IN_DB(db, db.auth_user, '%(id)s %(first_name)s
%(last_name)s')),
>>> Field('f_coname', 'reference t_companies', label='Company',
writable=True, readable=True, notnull=True, required=True, ondelete='NO
ACTION', requires=IS_IN_DB(db, db.t_companies, '%(id)s %(f_coname)s'))
>>>I also defined User_Has_Companies which has 2 columns USER_ID and
COMP_ID together should form a PK.
You don't need the "required" attributes as they are covered by IS_IN_DB.
Why do you have the ondelete in there?
DAL doesn't support multi-column primary keys.
This is awfully ambitious. Why don't you cut out a lot of the code and see
if you can get it working something like the example in the on-line manual?
