Initially posted this to django-users, having completely forgotten about the existence of django-dev. Sorry about that.
Currently, it is unclear as to how apps that override admin templates should maintain compatibility with both 1.3 and 1.4 when referring to the admin media file URLs in the overridden templates. This applies primarily to third-party apps like django-admin-tools, that want to support at least the latest two major Django versions. The changes I'm referring to are ones in the giant r16487 commit ( https://github.com/django/django/commit/09cccc395597145d35f3793d57f70b7795214f64 ). Since that change, Django now constructs URLs using `{% static "admin/ css/base.css" %}` internally, instead of the old `{% admin_media_prefix %}css/base.css` method. That change also saw the removal of `ADMIN_MEDIA_PREFIX = '/static/admin/'` from djago.conf.global_settings. This results in the following dilemma for any app that wishes to maintain compatibility with both 1.3 and 1.4: To maintain support for 1.3, the app cannot use {% static %}, as it is not available yet, so it uses {% admin_media_prefix %}, which causes a PendingDeprecationWarning that we're OK to ignore. However, due to the removal of the default ADMIN_MEDIA_PREFIX value, the {% admin_media_prefix %} tag no longer works as expected, returning "css/ base.css" instead of "/static/css/base.css". To overcome this, the app needs to ask that the project define an ADMIN_MEDIA_PREFIX, or define one itself, nether of which is desirable. Furthermore, having an ADMIN_MEDIA_PREFIX defined now triggers a DeprecationWarning, which is visible, and we're not OK to ignore it anymore. Of course, the app can provide its own {% admin_media_prefix %} tag, where it checks for ADMIN_MEDIA_PREFIX first, and returns STATIC_URL/ admin if it's not found, but this seems like the kind of functionality that should be provided by Django itself, to reduce the number of apps that will break with the upgrade to 1.4. I'm happy to write a ticket and a patch, but just wanted to hear from the core devs' opinion on the issue first. -- You received this message because you are subscribed to the Google Groups "Django developers" group.
