[patch] Exclude filter for the admin

[[530]]

class Amodel(models.Model):

    field = models.ManyToMany(SomeOtherModel)

    class Admin:
        list_filter = ('-field') # just like ordering

Typo in example

class Amodel(models.Model):

    field = models.ManyToManyField(SomeOtherModel)

    class Admin:
        list_filter = ('-field') # just like ordering

Missing: Should also raise a not implemented error for date and booleanfields.

What does this do?

Instead of filtering the result in the admin it excludes, so you can get the results not matching that particular choice, foreignkey, manytomany relation.

Like Adrian, I had trouble figuring out what the -field syntax actually did. The fact that neither Adrian nor I could understand what this does at first glance implies it needs a bit more thought. I'm +0 on the concept, however, so perhaps you can come up with a more obvious implementation?

Marking as wontfix given the comments above. If someone can provide a good example of how/when this would be useful, then please reopen.

So let's say we have a Posts model, it has a field called Flag, Flag can have a tri-status: normal, sticky, and obsolete, now I show only posts other than obsolete. How can I do that easily in Django admin?

This can now probably be done using custom filters. However, I want to say I need something like this.

I'm doing filtering on member__options and some of those options are don't send email (pk 42). I want to list (in the admin) all the members who *don't* belong in the don't send email-group. (So, the people I *can* send email to)

So really, having ?member__options__not=42 do it's magic would be swell.
