How can I force django to restart a database connection from the shell?

Question

I have a django project on a Digital Ocean server. From my local machine, I connect to the database through ssh:

ssh -L 63333:localhost:5432 me@my.server
         


        

Answer 1

from django.db import connections, connection
for conn in connections.all():
    conn.close_if_unusable_or_obsolete()

then call connection.cursor will get a fresh connection, django source code:

def _cursor(self, name=None):
    self.ensure_connection()
    with self.wrap_database_errors:
        return self._prepare_cursor(self.create_cursor(name))
