class BookAdmin(admin.ModelAdmin):
    model = Book
list_display = ['title', 'get_name']

def get_name(self, obj):
    return obj.author.name
get_name.admin_order_field = 'author'
get_name.short_description = 'Author Name'
admin.site.register(Book, BookAdmin)
Can "list_display" in a Django ModelAdmin display attributes of ForeignKey fields?
