如何在Django中创建具有两种不同状态的过滤器

Question

I want to create a filter in Django admin which would return records with two different statuses by single "filter" defined as one of:

def lookups(self, request, model_admin):
    return (
        ('1', 'class 1'),
        ('2', 'class 2'),
        ('3', 'class 3'),
        ('4', 'class 3')
    )

I'm using an API that returns to me all statuses with two extra statuses which I don't need.

def queryset(self, request, queryset):
    if self.value() == 'all':
        return queryset.filter()
    else:
        return queryset.filter(client__status=self.value())

In my filter list I want to have just one logical item clients with status x which would give me all clients with status M and status N.

def queryset(self, request, queryset):
    if self.value() == 'all':
        return queryset.all()
    elif self.value() == 'clients with status x':
        return queryset.filter(client__status__in=['M', 'N', ])
    else:
        return queryset.filter(client__status=self.value())
