[patch] FileUploadField should allow for clearing the field

[Adrian Holovaty]

It's currently not possible to clear the value of a FileUploadField.

I'm setting this to normal priority - it's needed fairly often and should definitely be possible from the admin interface.

Notes for file_del.patch.

• I guess things will have to change for this to work in magic removal branch.
• The solution provided works for me but suggestions how to improve it are welcome.
• Needs more testing.

Patch for admin app to allow deleting of files.

[anonymous]

it is not working for me (with Images ) so I've change it to:
##

obj = get_object_or_404(mod, pk=object_id)
try:

delete_f = getattr(obj, 'get_%s_filename' % attname)
f=delete_f()
os.remove(f)
obj.image=
obj.save()

##

---

of course it should be better way.

    obj = get_object_or_404(mod, pk=object_id)
    try:
        delete_f = getattr(obj, 'get_%s_filename' % attname)
        f=delete_f()
        os.remove(f)
        obj.image=''
        obj.save()

Reopening because it's not fixed.

We're proposing a solution to this issue here:

Comments please :)

The proposed solution mentioned in my previous comment has been extended and submitted as a patch. Since the patch also addresses the problem of FileField not working properly when core=True, we've started a new ticket for it here: #2534.

Closing as duplicate of #2534 (which supersedes this one).

Milestone Version 1.0 deleted

As far as I can tell, this issue was never fixed, and #2534 was later closed as invalid.

Even with Django 1.0, newforms-admin, and the removal of core fields, it is not possible to have a model with an optional FileField, and remove the value/file associated with that field through the automatic admin. Which is what this ticket was really about if I'm not mistaken.

Granted, it is possible to do this by customizing the admin (i.e. a custom model admin with a custom model form, for every model where this is needed).

But is this not considered a common enough use case to support without customization? In all seriousness I'm perplexed by the apparent lack of requests for this.

FileUploadField no longer exists making this specific ticket invalid. However, Django should support the ability with FileField's in general. #7048 is what we will be doing in a future release of Django. Marking this a duplicate in favor of the other ticket due to the invalidness of this ticket applying to current day Django.
