I switched the GQL Query to the following.
Now the GQL Query no longer gives 500 severe error, but almost
anything I code after that does give the 500 severe error.
I need to test if I returned any rows or not, ideally one.
taskLogs = db.GqlQuery("SELECT * FROM TaskLog where taskCode = :
1 " +
" and workerEmail = :2 " +
" and eventStartedDateTime = :3",
taskCode,
users.get_current_user().email(),
startedTime);
#if taskLogs is None:
# DebugText = "No rows returned"
###if len(taskLogs) <> 1:
### DebugText = " Error: more than one matching row found "
#else:
#DebugText = DebugText + " len(taskLogs) = " +
len(taskLogs);
#for taskLog in taskLogs:
# taskLog1.eventStartedDateTime = datetime.datetime.now
();
# taskLog1.put(); #save to BigTable database
# DebugText = DebugText + " Updated Row "
If I un-comment these two statements, I get the 500 severe error:
#if taskLogs is None:
# DebugText = "No rows returned"
So why don't I get some kind of trapped error? I'm finding the only
way to code this is to keep commenting out lines, and adding them back
in, and taking them out until something seems to work.
Even when I remove the date/time test, the following code runs:
taskLogs = db.GqlQuery("SELECT * FROM TaskLog where taskCode = :
1 " +
" and workerEmail = :2 ",
taskCode,
users.get_current_user().email()
);
if taskLogs is None:
DebugText = "No rows returned;"
###if len(taskLogs) <> 1:
### DebugText = " Error: more than one matching row found "
else:
DebugText = DebugText + "Rows Returned"
#DebugText = DebugText + " len(taskLogs) = " +
len(taskLogs);
for taskLog in taskLogs:
taskLog.eventCompletedDateTime = datetime.datetime.now
();
taskLog.put(); #save to BigTable database
DebugText = DebugText + " Updated Row; "
What is the proper way to test the number of rows returned?
Thanks again,
Neal Walters
