Finding the last modified timestamp for a group of Models

2024-02-27 Thread Alex Guetsche
I have an application which contains more than one Model, all descended 
from an abstract one. All the operational Models have created and modified 
fields 
with datetime timestamps. [How] can I get the Django ORM to bring me the 
last modified timestamp that will be the maximum of all createds and 
modifieds of all Models? Right now I have to use itertools for a quite 
convoluted expression over query sets of all the models involved.

It seems quite an obvious use case, and it can be implemented in pure SQL 
quite easily.
