Have you checked what 'd' is here? It may be something different than
you'd expect or hope, in particular for the __dict__[d] lookup (not
sure what you're expecting here).
I would actually work with something like
Person.objects.filter(id=pID), which keeps b a QuerySet instead of
turning it into an object, and then do more filtering later on.
But, from the error message, I'm guessing that's actually not (yet)
your problem. It complains about the 'text' attribute that cannot be
found, which would suggest that that field doesn't exist in the actual
database (it's there in the model). Did you sync the database, and
then later added the text attribute to Blog (or even the whole Blog)?
Btw, where in your view is line 53? I'm guessing at "b =
Person.objects.get(id=pID)"?
It may be that you need recreate the database part for this app. One
way to do this is to just to simply move the current database aside,
and run python manage.py syncdb again. That gets rid of all current
entries though.
You could also try to output the new sql (python manage.py sql <app>),
and see what you'll need to add in the database directly.
Good luck
