my function to delete a medecine from its table in views.py
===========================================
def delete_medecine(request,medecine={}):
print "------>>",request.POST
list = []
for i in request.POST['del_id']:
m = Medecine.objects.get(id = i)
m.delete()
return HttpResponseRedirect('/medecine')
Ah! Your code is fine, apart from one detail: the request.POST looks
like a regular dictionary, but it isn't. It is a querydict, look at
https://docs.djangoproject.com/en/dev/ref/request-response/#django.http.QueryDict
your request.POST['del_id'] effectively calls __getitem__('del_id') on
the querydict and the querydict documentation says:
"If the key has more than one value, __getitem__() returns the last value."
Now you know why only the last item gets deleted. It bit my once, too.
What you need to call is request.POST.getlist('del_id'): that will give
you the list you're expecting.
