----------------------------+--------------------
I have a Model called Person with the following constraint:
unique_together = ('name', 'country')
Furthermore I have a view to to edit a Person:
----------------------
def edit_climbing_place(request, person_id):
person = get_object_or_404(Person, pk=person_id)
print person.name
if not request.method == 'POST':
form = Person(instance=place)
else:
form = Person(request.POST, instance=place)
if form.is_valid():
form.save()
return HttpResponseRedirect(reverse(start_page))
print person.name
return render_to_response('myProject/edit_person.html', {'form' :
form, 'person': person}, context_instance=RequestContext(request))
------------------
In the above code if form.is_valid() fails due to the 'unique_together'
constraint is not satisfied then the two 'print person.name' outputs are
different. In other words if I edit an existing 'Person' (say A) and
change the name to a name which matches an already existing person (say B)
in the same 'country' then in the above view the variable 'person.name'
changes to that of B. All other fields, however, stay the same.
