Database errors in Django when using threading

Question

I am working in a Django web application which needs to query a PostgreSQL database. When implementing concurrency using Python threading interface, I am getting DoesNotEx

Answer 1

Becomes more clear from this part of the documentation

class LiveServerTestCase(TransactionTestCase):
    """
    ...
    Note that it inherits from TransactionTestCase instead of TestCase because
    the threads do not share the same transactions (unless if using in-memory
    sqlite) and each thread needs to commit all their transactions so that the
    other thread can see the changes.
    """

Now, the transaction has not been committed inside a TestCase, hence the changes are not visible to the other thread.
