Re: Dynamic columns in admin changelists
For me the #django IRC chat logs have given me much success as a reference point as I am a beginner with django. That search on there for me is a goldmine.

Re: Dynamic columns in admin changelists
Thanks Malcolm, That was so much easier than I was expecting: class ItemOptions(admin.ModelAdmin): def changelist_view(self, request, extra_context=None): self.list_display = request.session['item_columns'] return super(ItemOptions, self).changelist_view(request, extra_context) Incidentally - while reading around it I found this page which is a treasure trove: http://code.djangoproject.com/wiki/NewformsHOWTO#Q:HowdoIaddanextracolumntothechangelistview If anyone ever want to expands the 'customising the admin' sections of the docs then that's the page to look at.

I haven't tried it, but a couple of minutes looking at the code suggests it shouldn't be too hard. The admin display, by design, is a class-based setup, with particular methods you can override. If you look at the ModelAdmin.changelist_view() method -- which is the one responsible for the page you're interested in -- you'll see that it creates the page using information from attributes on "self". So you could override that method, set up self.list_display and self.list_display_links appropriately and then pass off control to the base class method. That's pretty much the intention of the admin system design: you override the methods you want to change, often just setting up the instance slightly differently before returning to the normal execution paths.
