How can I use Django QuerySets with multiple databases?

How can I use Django QuerySets with multiple databases?

You can use Django's database routing feature to manage multiple databases. First, define your databases in the settings.py file.

What if I want to query data from both databases in a single QuerySet?

You can't directly combine QuerySets from different databases, but you can fetch data separately and merge it in Python.

Can you show me an example of how to set up database routing?

Sure! In your settings.py, you can define a DATABASE_ROUTERS setting that points to your custom router class.

What are some common use cases for multiple databases in Django?

Common use cases include separating read and write databases, using different databases for different apps, or integrating legacy systems.
