You are right. crud forms should not be acceped. do this:
def f(form):
app=meeting.name # somehow determine which name
db_path = os.path.join(request.folder,'databases',app)
os.path.rmdir(db_path) # you may need to clear recursively
form=crud.delete(db.meeting,meeting.id, ondelete=f)
if form.errors:
response.flash = 'Invalid data.'
return dict(form=form)
