What are some examples of database routers in Django?

Django database routers allow you to control which database to use for read and write operations. For example, you can create a router that directs all read operations to a replica database and write operations to the primary database.

Can you show me a code example of a simple database router?

Sure! Here's a basic example:

class MyAppRouter:
    def db_for_read(self, model, **hints):
        return 'replica'

    def db_for_write(self, model, **hints):
        return 'default'

    def allow_relation(self, obj1, obj2, **hints):
        return True

    def allow_migrate(self, db, app_label, model_name=None, **hints):
        return db == 'default'

How do I configure this router in my Django settings?

You can configure the router in your settings.py file like this:

DATABASE_ROUTERS = ['path.to.MyAppRouter']

Are there any best practices for using database routers?

Yes, it's best to keep your routing logic simple, ensure that your routers are well-tested, and document their behavior to avoid confusion.
