Sort list of items in Django

I have a Django view called change_priority. I'm posting a request to this view with a commas separated list of values which is basically the order of the items in my model. The data looks like this:

1,4,11,31,2,4,7

I have a model called Items which has two values - id and priority. Upon getting this post request, how can I set the priority of the Item depending upon the list order. So my data in the db would look like.

1,1
4,2
11,3
31,4
2,5
4,6
7,7

Thanks guys.

You don't really give much detail about how exactly you're receiving the information, but here's a stab at it.

order = data.split(',') # convert data string to a list
objects = MyModel.objects.in_bulk(order)
for i, id in enumerate(order):
    obj = objects['id']
    obj.priority = i
    obj.save()
