Thanks Antony for your concise answer!
I have tried it in the app code - it did not work, giving me no error. I
have tried your code in the terminal and it looks the code does not create
new table field. Any idea why it does not work? Maybe its my db settings? I
use sqlite db. Your help would very helpful to me as all my app dependent
on this function.
Here is my trial in a terminal:
>>> from gluon import DAL, Field
>>> db = DAL('sqlite://se2.sqlite',check_reserved=['postgres',
'postgres_nonreserved'],pool_size=10,lazy_tables=True, migrate=True,
fake_migrate=False)
>>> ta_args = dict(format='%(f1)s')
>>> db.define_table('ta', Field('f1', 'string'), **ta_args)
>>> db._tables
['ta']
>>> db.define_table('ta', db.ta,Field('newfield', 'string', default =
'abc'),redefine=True, **ta_args)
>>> db.ta._fields
['id', 'f1']
