Question

Does Django come with sqlite bundled or is it a separate module?

Can’t figure this out, even by looking at Django source:
https://code.djangoproject.com/browser/django/trunk/django/db/backends/sqlite3

Answer 1

You’re looking for this:

21  try:
22      try:
23          from pysqlite2 import dbapi2 as Database
24      except ImportError, e1:
25          from sqlite3 import dbapi2 as Database
26  except ImportError, exc:
27      from django.core.exceptions import ImproperlyConfigured
28      raise ImproperlyConfigured("Error loading either pysqlite2 or sqlite3 modules (tried in that order): %s" % exc)

It first attempts to import PySqlite, an external module. If that fails, it tries to import the sqlite3 module included in Python 2.5+. If neither Python 2.5+ nor the external module are installed, it fails. It does not include its own copy.
