[web2py] Howto create parent and children at same time?

[Keith Pettit]

I have a ticket system for trucks.  Each ticket or parent has 1 or more 
loads (children).  I'm having trouble figuring out how to create a (parent) 
and multiple children at the same time.  

I'm trying to avoid going through a dialog where they have to fillout a 
ticket, save, then add loads. I want to have a single screen where I can 
create the parent and multiple children at the same time.


Here is my basic model:
# Ticket Information
db.define_table('ticket',
   Field('type', db.loadtype),
   Field('vehicle_id'),
   Field('misc', 'text'),
   Field('working', 'boolean'),
   Field('approved', 'boolean')
)
db.ticket.type.requires = IS_IN_DB(db, 'loadtype.id', 'loadtype.type')


# Loads for a ticket (usually just one, but sometimes many)
db.define_table('load',
   Field('ticket', db.ticket),
   Field('container_id'),
   Field('entered', 'datetime'),
   Field('updated', 'datetime'),
   Field('product', db.product)
)


Thanks for any help,
