Я устанавливал джанго в 1.8 почем стоит 1.3.7???

I installed Django in 1.8 how much does it cost 1.3.7 ???

I'm guessing that you're asking why your web app is running 1.3.7 and not 1.8. To use 1.8, you'll need to create a virtualenv and install it there and then use the virtualenv for your web app. There is documentation for all of these on the help pages.
