I am not using different datasets, or using different queries. So here we go, let me explain in every minuet detail this process.
>>> cd ~ >>> hg clone https://web2py.googlecode.com/hg web2py >>> cd web2py >>> ln -s ~/path/to/my/application applications/pms >>> python web2py.py -a <recycle> *go to 127.0.0.1:8000/pms/default/index *everything works perfectly, I see the page as it should be with records in place, providing the proper "names" (this is only three records, I KNOW they have values) >>> kill -SIGTERM <web2py process id> >>> cd gluon/ >>> mv sql.py sql.bak.py >>> ln -s dal.py sql.py >>> cd .. >>> python web2py.py -a <recycle> *go to 127.0.0.1:8000/pms/default/index *receive stacktrace. >>> kill -SIGTERM <web2py process id> >>> cd gluon/ >>> rm sql.py >>> mv sql.bak.py sql.py >>> cd .. >>> python web2py.py -a <recycle> *go to 127.0.0.1:8000/pms/default/index *behold, everything works perfectly. Even IF, and I say IF my dataset has a bad reference to a None record, and it executes just fine with sql.py, it should execute with dal.py exactly the same, it should not be throwing the exception. -Thadeus On Wed, Apr 7, 2010 at 10:10 PM, Massimo Di Pierro <mdipie...@cs.depaul.edu> wrote: > I assume it is > >> db.dog.owner.represent = lambda value: "%s" % db.person[value].name > > The stacktrace you get is because one of your records has owner==None hence > db.person[value] is also None and None has no .name.
