I love Django, perhaps mostly because I love Python but Django's ORM is lovable in its own right. Using it, fronted by Nginx, I've built sites ranging from the simple (like mine here) to the highly complex such as the (team built) liquid site.
Django is excellent for developing sites that present data where the presentation is largely static. The page templating and modelling capabillities make it very fast and productive when doing back end (server side) work.
It is not good for highly interactive, typically single page, applications. These are becoming increasingly common thanks to the likes of AngularJS making them easier than ever to implement.
Lately, I've found myself using AngularJS on projects because it facilitiates user interaction making data visualisation easier and more flexible.
Another thing I have to do a lot with Django applications is carry out data migrations to update the schemas to accomodate change. These are routine for me but they take time which can be frustrating.
The links above give plenty of detailed introductions. I'm looking closely at using MEAN on future projects because it does away with most migrations, focuses development on a single language and facilitates the development of highly interactive applications.
