admin list_filter: limit choices to model values?

[Micky Hulse]

Hi.

Not sure where to start... Just hoping someone can give me a kick in
the right direction.

I have built a flat page app that allows for an author FK (optional field).

When I setup the admin to allow author as a list_filter, the actual
filter list of authors is way to long to be useful.

Would it be possible for me to setup my list_filter to only show
author names that have been assigned to my flat pages? For example,
let's say I have 10 pages, and two of those pages have the been FK'd
to "bjohnson" and "fjackson"... In my list_filter view, I would like
to only see "bjohnson" and "fjackson".

Does any of this make sense? :D

Any tips and/or advice would be awesome.

Thanks!
Micky

Maybe simpler: Is there an easy way to limit the list_filter to folks
with "Superuser status"?

Just as an update, I found this:

<https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_filter>

... and it looks like what I need... Unfortunately, it's new in trunk
(I'm on 1.3).

I am hoping there's something similar to SimpleListFilter in 1.3.

I'm now trying to figure out how to browse Django source for version 1.3. :)

I will post back with more info if I figure something out.

Thanks!

Cool, found 1.3 source:

django/branches/releases/1.3.X
<https://code.djangoproject.com/browser/django/branches/releases/1.3.X>

Looks like maybe FilterSpec might be what I want:

<https://code.djangoproject.com/browser/django/branches/releases/1.3.X/django/contrib/admin/filterspecs.py>

At least now I have a better idea of what to Google for "django
FilterSpec author". :)

Thanks!

In 1.4/trunk, looks like filterspec.py gets replaced by filters.py (as part of adding the ability to filter a list_filter), so we'll just sit tight and wait for 1.4 to be released (rather than have to go  back and remove the defunct filterspec code).

Related to my original question:

On top of needing to limit list_filter in the admin, I also needed to
limit the user choices in my FK to auth.user. This bit of code does
just that:

<https://gist.github.com/1719713>

Just thought I would share the code to help others.

I am wondering if I can apply the same logic, as a method, to list_filter?

list_filter = SomeMethod()

(probably not, but that would be nice)

Anywho... Anyone know when Django 1.4 is scheduled to be released?

The Django 1.4 roadmap

Before the final Django 1.4 release, several other preview/development
releases will be made available. The current schedule consists of at
least the following:

* Week of January 30, 2012: First Django 1.4 beta release; final
feature freeze for Django 1.4.

* Week of February 27, 2012: First Django 1.4 release candidate;
string freeze for translations.

* Week of March 5, 2012: Django 1.4 final release.

If necessary, additional alpha, beta or release-candidate packages
will be issued prior to the final 1.4 release. Django 1.4 will be
released approximately one week after the final release candidate.
