I have code as
view_a(request):
.... Populate my_a, my_b and my_c...
try:
tp = TP.objects.get(a__exact = my_a, b__exact = my_b)
except TP.DoesNotExist, e:
tp = TP()
tp.a = my_a
tp.b = my_b
tp.c = my_c
tp.save()
else:
tp.c = my_c
tp.save()
This view is called by ajax calls. TP is a django model and mysql db.
I am using django 1.1.4/ python2.5/mod_wsgi2.5,
I find that in, one case, two rows with same value of a and b has been
created in DB. ( value of c was different)
What could have caused it?
Any clues or hints on how to track down this problem or what to look for
will be appreciated.
