save() failing during first test

At least that's what I think is happening. When I run the first test in the tutorial, I get an assertion fail saying that my post.slug is not equal to slugify(post.title). It says my post.slug is blank. According to the terminal: " AssertionError: u' ' != u'test-blog-post' ". From my knowledge, my code is identical to yours, but I am running on Django 1.5. Could that be the issue?

I get nothing but a blank when printing it out.

Your code looks correct but obviously something is acting up. Put `print post.slug` before the `self.assertTrue(` line in the test and check the output when you run your tests.
