SchoolTool

In Journal view, every Thursday is "missing" for 1 unique teacher

Asked by Neville Turner

We have 27 teachers and the school year is divided into 3 terms. 1 unique (and only one that we can identify) teacher's Journal of student attendances does not show any Thursday in Terms 2 & 3 only. I.e., Term 1 shows each day (including Thursdays) correctly, but terms 2 & 3 are missing all occurrences of Thursdays. No other teacher has this problem. I have no idea what logs to send, so please let me know what further information I can send.

I have another instance of schooltool running on the same server, which I loaded in order to experiment. However I discovered that any changes (deletions etc) made to that instance also had the same effect on the production version. It's called "Schooltooltest". Perhaps that is conflicting in some way with the production version? Today's error log is pasted below.

If you have the server timezone set to your local time, try setting it to GMT.

Tom - thank you for your reply. I am not sure if by "Server timezone" you meant the timezone set in the Schooltool "Server" tab, or the physical server on which Schooltool is hosted (in my case Ubuntu 14.04). So, I tried setting the Schooltool "server" tab timezone to UTC (by removing the local +7 hr offset), but the only effect was to cause all calendar times to be wrong (as one would expect). It didn't effect the missing Thursdays.
I then tried setting the Ubuntu server's timezone. As you undoubtedly know, Ubuntu's time setting works by setting the system time on UTC and aplying a local timezone offset - in my case UTC +7. I tried removing the local time offset, thus causing the local time to show as UTC. Again no effect on the missing Thursdays. Of course I stopped and re-started the schooltool service after each change.

Thanks for your suggestion anyway.

Found it!

Sections...Year 3...Schedule.

I had missed ticking the "Thursday" Schedule for Terms 2 and 3 for this Section. Hence no Thursday showing for this teacher because she had no scheduled section on Thursdays.

Thanks for your help Tom.

Nev.

Glad you got that sorted and thanks for letting us know what the problem was. That kind of feedback helps us the next time we get a similar question.

I'm afraid our timezone implementation is buggy enough that fiddling with the timezone setting is my first response to any "I'm missing sections" question.
