I'm trying to find a solution to this very same issue. At the very least, I think inlines should support custom callables.
The inline I'm displaying is an intermediary table for a ManyToMany relationship. So I have a selector for the related object, but what I would like to do in the inline is also display a few of the fields on the related object. Take this (truncated) example. class Group status = Char class Member groups = ManyToMany through Membership member_since = Date class Membership group = ForeignKey member = ForeignKey order = Integer class MembershipInline model = Membership The membership inline works just fine for the primary goal of ordering the members in the Group. But it would be a nice visual aid to be able to display the member_since date in the inline. This is good information to inform the ordering. Right now I can't find a way to do this other than denormalizing and copying the member_since field onto the Membership Model. What I would expect is to be able to do is something like this. class MembershipInline model = Membership list_display = ('member_since',) def member_since(self, obj): return obj.member.member_since.strftime() member_since.short_description() On Jan 7, 5:32 am, frans <franshaar...@gmail.com> wrote: > On 7 jan, 11:15, Daniel Roseman <dan...@roseman.org.uk> wrote: > > > > > On Jan 7, 9:22 am, frans <franshaar...@gmail.com> wrote: > > > > Is this something which exists ?
