[LON-CAPA-users] teacher-assigned vs. student-selected slots: can they be mutually exclusive

[Stuart Raeburn]

Doug,

A correction to my previous e-mail to this thread:

Even if a "Period of time when this slot can only be uniquely chosen"  
is set for a student-schedulable slot, a student will still be able to  
reserve that (new) slot, if they already have another slot reserved in  
two cases:

(a) the existing slot does *not* have "Period of time when this slot  
can only be uniquely chosen" set.

or

(b) a unique period is set but it either ends before the start time of  
the new slot, or starts after the end time of the (new) slot.

So, in order to prevent a student reserving a slot in addition to the  
teacher-assigned slot, you need to set an appropriate "Period of time  
when this slot can only be uniquely chosen" for the teacher-assigned  
slot.

Unfortunately, the originally implementation of slots (in 2005) did  
not anticipate this, so the slot helper used by a Course Coordinator  
to create or edit a slot does not allow an exclusion period to be  
assigned to an instructor-assigned slot.

As it turns out, you can use the "Upload Slot List" button to upload a  
csv file containing a slot definition for a slot with type:  
"preassigned", and also an exclusion range (e.g., "6/27/2018  
00:00,6/28/2018 06:00"), but if you subsequently edit the slot  
settings using the slot helper the exclusion range will not be  
preserved.

Anyway I have implemented the following changes:

(a) Slot helper allows exclusion date range to be set for preassigned  
slot type.
(b) A preassigned slot with an exclusion range will now prevent a  
student scheduling another slot.

Those changes will be in 2.12, but if you would like to patch your  
current 2.11.2 installation, see bug 5915 (  
bugs.loncapa.org/show_bug.cgi?id=5915#c1 ) for details.
