Thanks Anthony.
Yahaaa. Now it works. As u suggested I have successfully changed settings
of lazy_tables to False and it works:
db = DAL('sqlite://se2.sqlite',check_reserved=['postgres',
'postgres_nonreserved'],pool_size=10,lazy_tables=False, migrate=True,
fake_migrate=False)
now I got right results:
>>> db.ta._fields
['id', 'f1', 'newfield']
Anthony I wonder what is wrong in the adding fields to the table in this
way? What is the maximum number of fields I can add db table?
Web2py community is the best one I have every entered in my life!!!
Anthony, thanks again for your help!!!
