Question

I’ve decided to play around a bit with Django (since I’ve heard so much about it). I’m walking through the tutorial here:

http://docs.djangoproject.com/en/1.2/intro/tutorial01/#intro-tutorial01

about halfway through the tutorial, i’m asked to run this from my command line:

python manage.py syncdb

However, I’m getting this error:

C:\django-projects\mysite>python manage.py syncdb
Traceback (most recent call last):
  File "manage.py", line 11, in <module>
    execute_manager(settings)

ValueError: Empty module name

here is the relevant part of my setup.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3.', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'c:/python25/ramysDB',                      # Or path to database file if using sqlite3.
        'USER': '',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

It looks like you don’t have your database configured right. Check your settings.py and make sure you have a valid database ENGINE defined:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': '',                      # Or path to database file if using sqlite3.
        'USER': '',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

You probably want django.db.backends.sqlite3? And set a NAME for it.

Update:

You have an extra period in ENGINE. Change it to ‘django.db.backends.sqlite3’. Hope that helps.
