Hello, If you select Django and Tryton, you need a connector because database o models are different
1- Add webservices in Django, for example, Tastypie. And a module in Tryton call this webservices. 2- If Django is in same server than Trytond, in your django view code you could import trytond. For me the best option. 3- You could import proteus in Django (could you run Django is not same server than Trytoind), but some moths ago, I read is low proteus when work with big data. Anybody could confirm this? 4- Migrate a Nereid. 100% integrated a Trytond.
