Hello Jorge
Thank you for the reply. admin_order_field can 1 and only 1 field.
However, I want to sort by multiple fields. Something like this:
function_name.admin_order_field = [ 'topic id', 'book id' ]
Now the previous line does not work but I wrote it just to show the
idea. if I choose to sort by the function, the admin page should sort by
topic id first then it should sort by book id.
I have seen ModelAdmin.ordering
<https://docs.djangoproject.com/en/1.6/ref/contrib/admin/#django.contrib.admin.ModelAdmin.ordering>
which sort of works. However, this one only specifies default ordering
for a model. I want to make something like this as the function ordering.
Thank you

Hey, it can be done, it's something like this:
In the Model Class where you created the function you are going to add:
function_name.admin_order_field = 'The field to order'

Hello,
I made a library application. I have books each with its own id
number (different from the autofield added by django). the book
has several foreign keys each with its own id.
I wrote a function that returns a long id number in string format
consisting of the book id number and id number of several of its
foreign keys.
say I have a topic foreign key. the function does something like this:
book id: 122
topic id: 4
the function returns: 04-0122
I show this id number in the admin page. I want to sort this item
which is not actually in the database by topic id then by book id.
however, admin_order_field only takes 1 property.
if i have for example the following:
04-0122
03-1002
04-0043
they should be like this in the admin page after sorting:
03-1002
04-0043
04-0122
is that possible?
Thank you
