Filtering Model Results for the Django admin Selection Window

I just started playing with Django today and still find it quite difficult to do simple things. Now I am trying to filter a list of state types. StatusTypes Model:

class StatusTypes(models.Model):
    status = models.CharField(max_length=50)
    type = models.IntegerField()
    def __unicode__(self):
        return self.status
    class Meta:
        db_table = u'status_types'

On one admin page, I need all the results, where type = 0, and on the other, I need all the results, where type = 1, so I can’t just limit it from within the model. How can i do this?

EDIT: I should have been more clear. I have a Unit model that has a foreign key to StatusTypes. Models are as follows:

class StatusTypes(models.Model):
    status = models.CharField(max_length=50)
    type = models.IntegerField()
    def __unicode__(self):
        return self.status
    class Meta:
        db_table = u'status_types'

class Unit(models.Model):
    name = models.CharField(unique=True, max_length=50)
    status = models.ForeignKey(StatusTypes, db_column='status')
    note = models.TextField()
    date_added = models.DateTimeField()
    def __unicode__(self):
        return self.name
    class Meta:
        db_table = u'units'

So, now on the administration page for the device model, I want to limit the status only to those who have type = 1. Based on the answer of lazerscience below, I tried the following code:

from inv.inventory.models import Unit
from django.contrib import admin

class UnitAdmin(admin.ModelAdmin):
    def queryset(self, request):
        qs = super(UnitAdmin, self).queryset(request)
        return qs.filter(type=0)

admin.site.register(Unit, UnitAdmin)

. qs, , , - ?

EDIT 2: , , , Unit.

queryset MyModelAdmin:

from django.contrib import admin

class MyModelAdmin(admin.ModelAdmin):

    def queryset(self, request):
        qs = super(MyModelAdmin, self).queryset(request)
        return qs.filter(type=0)

admin.site.register(StatusTypes, MyModelAdmin)

type=0!
