Hi Becka,
So it seems like, from reading your code, that I can diagnose your issue.
When a user clicks "sign up", in say the Thursday Shifts Available table,
the browser sends a POST from this form:
<form method="post">
{% csrf_token %}
<div class="hiddentext">
{{shift.meal}}
{{shift.meal}}
{{shift.camper}}
</div>
<input type="submit" value="sign up">
</form>
This POST includes the keys 'csrf_token', 'camper, 'meal', & 'meal' but not
'shift_id'. Therefore, in
if request.method == 'POST':
shift_id = request.POST.get('shift_id')
signup_for_shift(shift_id, request.user)
return redirect('signup')
request.POST.get('shift_id') returns None.
When that gets passed to mealShifts.objects.get(pk=shift_id), it raises
the error.
You can confirm that by inserting the line
import pdb;pdb.set_trace()
before that line and run `print(request.POST.get('shift_id'))` when the
django toy server hits that breakpoint.
