Django, multiple databases with raw sql. How to choose db?

Question

I have a Django project that utilizes multiple databases. https://docs.djangoproject.com/en/dev/topics/db/multi-db/

I perform a lot of raw queries like this:

  cursor = connection.cursor()
  cursor.execute("select * from my_table")
  ....
  transaction.commit_unless_managed()

How can I specify which database to use?

Answer 1

Refer django docs on executing custom query directly. Specify database in your connection as given below:

from django.db import connections
cursor = connections['db_alias'].cursor()
cursor.execute("select * from my_table")

And then commit using

from django.db import transaction
transaction.commit_unless_managed(using='db_alias')
