在Django Admin中，有没有办法在没有自定义超文本标记语言的情况下，添加一个自定义的autocomplete_field，在保存时为模型字段提供一个查询集？

from django.contrib import admin
from .models import MyModel

class MyModelAdmin(admin.ModelAdmin):
    autocomplete_fields = ['related_field']

admin.site.register(MyModel, MyModelAdmin)

from django.contrib import admin
from .models import MyModel

class MyModelAdmin(admin.ModelAdmin):
    autocomplete_fields = ['related_field']
    
    def get_search_results(self, request, queryset, search_term):
        queryset, use_distinct = super().get_search_results(request, queryset, search_term)
        queryset = queryset.filter(related_field__icontains=search_term)
        return queryset, use_distinct

admin.site.register(MyModel, MyModelAdmin)
