Works perfectly, thanks :) Tested with a join 4 levels deep too and
it made just one query.
I use select_related elsewhere for more generic optimizations but it

Hi John,
Use select_related [1] to tell Django to 'follow' the foreign key. Try

testmodels =

Hello.
I want to register users.
So I made a RegisterForm(ModelForm):

Hey,
I'm trying to improve the performance of a Django app, and noticed
that you can't seem to properly defer fields when making lookups with
joins. To demonstrate, I set up a test project with the following
models:

other = models.ForeignKey('OtherModel')

overwrite the models's delete() method where you decide wether to delete or

You can upgrade the "inspectdb" result with Django Autoadmin (

basic AdminModel classes on the fly, without the need for manual
