How to competently implement work with external data?

Question

Django

Making my first prototype, immediately hit a dead end.
My application needs to actively use data from an already existing database.
It has a correspondence between object IDs and their names, various information about the same objects, etc.
How to competently implement work with these external data?
For example, in the django database, I want to store only object IDs, and get their names from another database. Check ID for validity, etc.

Answer 1

Django works with multiple databases like this .
At the same time, the entire set of Django functionality (models, managers, etc.) is available for all bases of your project.
