Django - User admin - adding groups to list_display

Question

As we know, ManytoMany relations can't be listed in list_display. Is there any work around to make it like group1, group2 etc?

Answer 1

I don't understand your example (group1, group2) but you can certainly use any function as a column in the changelist view, which means you can likely do what you want to show!

Example:

class MyModelAdmin(admin.ModelAdmin):
    list_display = ('foo', 'bar')

    def foo(self):
        return "This column is Foo"

    def bar(self, obj):
        try:
            return obj.m2m.latest('id')
        except obj.DoesNotExist:
            return "n/a"


    # there's a few more things you can do to customize this output
    def bar(self, obj):
        return '<span style="color:red;">By the way, I am red.</span>'

    bar.short_description = "My New Column Label"
    bar.allow_tags = True
