Thank you, I deleted the file, and changed the db.define_table like this:
db.define_table('NFobj',
...,
migrate = False, fake_migrate = True
)
As long as I leave these settings like this, everything works.
I wonder is there any case or an action witch I will not be able to
accomplish in the future due to these settings?
I am not so experienced with web2py. I haven't tried to do the database
migration, but what If want to do the database migration in the future?
Does the migrate=False setting restricts web2py to do the migration?
