It isn't an error, only a suggestion, about 3rd tutorial

[alexandre]

First of all, congratulations for your work.

I'm reading your tutorials, and they are very interesting, but in the [3rd], you don't talk about locals(), perhaps you do in after documents, but I think that locals() at time of render a webpage is a very quickly and easy way to show information, but you don't talk about it.

Congratulations again for your work.

Regards,

Feeding locals() into a template context is a good way to expose data you didn't want to expose. As such, it's not something a Django tutorial should be recommending.
