I think this book is excellent. It takes you through the ins and outs of Django in, for me at least, a really informative and easily understandable way.
I found the online Django tutorial left out the 'why' in the examples and so I really needed something that explained in depth what is possible.
It gets a four out of five stars only because it's a bit old now and could do with a new edition, but that shouldn't affect you too much. Django hasn't changed that much in three years.
