如何在Django Admin中筛选出或不包括模型管理多选小部件中的某些记录？

from django.contrib import admin

class CustomFilter(admin.SimpleListFilter):
    title = 'Custom Filter'
    parameter_name = 'custom_filter'

    def lookups(self, request, model_admin):
        return (
            ('option1', 'Option 1'),
            ('option2', 'Option 2'),
        )

    def queryset(self, request, queryset):
        if self.value() == 'option1':
            return queryset.filter(field__contains='option1')
        if self.value() == 'option2':
            return queryset.filter(field__contains='option2')

from django.contrib import admin
from .models import MyModel

@admin.register(MyModel)
class MyModelAdmin(admin.ModelAdmin):
    list_filter = (CustomFilter,)
