I need some help with a validator for my test db.
Here's my model:
db.define_table('test',
SQLField('parent','reference dset'),
SQLField('name','string')
)
I want a validator that says that the default test.parent value should
be 0 and that the allowed values are 0 and any other value that
IS_IN_DB(db,'test.id','%(name)s').
It would also be nice if "No parent" could be the name for the id=0.
OR is the best way to do this simply to declare a root node with
test.id==1? Somehow, I don't like this idea as much.
