django - reusing functions in many views

阅读更多关于 django - reusing functions in many views

I have a bunch of functions that I created in some views that must be reused in many other views. Do I need to create a class and put those functions in a class?

I started a django project for my personal website to learn django. So far I've got my development environment set with everything I need and followed this great tutorial to create some basic data structures and templates. Now I would like to start using my html layout I made before and start implementing the functionalities to it. However I'm having hard time understanding how to accomplish this. I've mostly done java portal solutions before this where I could start the server, create some pages, set my theme for them and then add custom portlets (the functionalities/code) wherever I wanted.
