Dropping to ipython from Django

Today I wanted to debug some of our unit tests, so I wanted to drop to a shell from inside a test case. Here's how that can be done:

import IPython
IPython.embed()

In previous versions this used to be:

from IPython.Shell import IPShellEmbed
ipython = IPShellEmbed()
ipython()

The first two lines go somewhere in your module and the latter wherever you want to hook up with the shell (tests, models, views). This can serve as a more rich alternative to ipdb.set_trace().
