Answer 1

You mean an outdated manual. The hashcompat module hashcompat been removed in Django 1.6, as you can read here .

Either install an older version of Django (1.5 or previous), or get a newer tutorial. You can also manually fix your code using Python's built-in functions, as indicated in the deletion notification, but for a beginner it can be a bit of a hassle :)

Answer 2

I solved this using hashlib . I just added:

 try: from hashlib import sha1 as sha_constructor except ImportError: from django.utils.hashcompat import sha_constructor 

Answer 3

hashcompat is already deprecated in django 1.6, it is better to use hashlib instead

Answer 4

If you still follow this, the version of django used in the book is 1.1 , and if you are using a higher version of django , try removing djangodblog from the list of applications in the setting.py file. It should work.
