Queryset in newform: form_for_model()

[MarioGonzalez <gonzalemario @…>]

Hello:

I usually show forms using form_for_model(), however there's something I think is missing. My model is something like:

class TransferFile(models.Model):
        file = models.FileField(upload_to="/some/path/in/my/system/")
        owner = models.ForeignKey(User, db_column="owner", db_index=True)
        authorized_account = models.ManyToManyField(User,
related_name="authorized_account")

        class Admin:
                pass

        class Meta:
                permissions = (
                        ('send_file', 'Can send files'),

In my DB I've got lot of users, each one with different groups and permissions, and I don't want to show them in my form. So, I want to pass a parameter in form_for_model() to change the queryset. I wrote a patch for that, I know it needs improvements but it's for explain my idea.
Please see the talk we're having in ​http://groups.google.com/group/django-developers/t/1e4714a469a1a814

This can be easily accomplished with just using the formfield_callback. form_for_* helper functions are not meant for special cases, thats why formfield_callback exists.
