filtering dropdown values in django admin

Question

class Foo(models.Model):
    title = models.TextField()
    userid = models.IntegerField()
    image = models.CharField(max_length=100)
    def __unicode__(self):
           


        

Answer 1

You could subclass your own model.ModelAdmin and create a custom field for your ChoiceField...

class CustomForm(model.ModelForm):

    class Meta:
        model = Foo

    foo = forms.ChoiceField(widget=forms.Select, initial=self.foo_queryset)

    def foo_queryset(self):
        return Foo.objects.filter(xy)...

class FooAdmin(model.ModelAdmin):
    form = CustomForm
