Post your code here, and someone will help you figure out why it does
not work like you expect.

According to the docs [1], you may need to install PyYAML:

Thanks a lot Jirka. Calling this from inside each thread seems to have done
it for me:

>>> from django.db import connections
>>> for connection in connections.all(): connection.close()

How to get hold of a (database) connection from within a thread

[Joseph Wayodi]

Hi people,

I am running some Django code that creates objects in the database. I am
using PostgreSQL via psycopg2. However, I am running this code from the
Django shell, and not as part of a request. I therefore have to handle a few
things manually, for example, closing connections to the database. The code
creates multiple threads to do the object creation, and I soon hit the
maximum limit of allowed connections to the database.

How can I get hold of the connection used to create the object, from within
each thread, so that each thread closes the connection that it has just
used? Alternatively, how can I get a list of all the open connections that
Django is using at any one time. I am using the "standard" model query API,
and not executing custom SQL directly.

Thanks,

Joseph.
