Hi Victor, I think this is a very good question. I've been considering what the best approach would be and decided on either using a decorator as you've mentioned or implementing class based views. You can create base view classes that load common data for the different types of pages. You would then have specific views subclass one of the base view classes to inherit the loading of the common data while acting on data specific to their view.
I'm curious if anyone else has any opinions or experiences loading common page elements in a clean and DRY manner. -- Alex On Thu, Sep 29, 2011 at 5:59 PM, Victor Hooi <victorh...@gmail.com> wrote: > Hi, > > We have a common navigation bar on nearly every page (view) that contains a > dropdown - this dropdown is populated with items from a database table.
