I have been working with Appengine for 3 months and this is my first post,
but I have read with interest correspondence in this group. Thanks for all
the valuable information.
My original problem was simple, or so I thought. I wanted to increment a
value and return it to the datastore. However, the value I do increment does
not return to the datastore incremented. The code below is my attempt to
find the problem, which I do but cannot explain or resolve.
I iterate over a "list". In a selected entity I attempt to increment the
"entrycount". I log the before and after incremented value. Works as
expected. However, when I am done with the first interation, I iterate over
the "list" again to review the "entrycount". As you can see by the log
below, the count on Alex has retuned to zero. How is this possible? What am
I missing?
for lst in list:
if self.request.get(lst.title):
logging.error('Title: '+lst.title+str(lst.entrycount))
contacts.groups.append(lst.title)
lst.entrycount = lst.entrycount+1
logging.error('Title: '+lst.title+str(lst.entrycount))
else:
logging.error('Owner: '+'No title read'+str(lst.entrycount))
for lst in list:
logging.error('Title: '+lst.title+str(lst.entrycount))
db.put(list)
contacts.put()
util.flushContacts()
return True
The ERROR prefix is meaningless. That is just my log output.
