diango之下拉选择处理（day-29）

关键词 autocomplete_fields = (“外键”,)
需要在admin class中定义 search_fields
附上代码：

from django.contrib import admin
# Register your models here.
from .models import Country, Province
class ProvinceAdmin(admin.ModelAdmin):
    list_display = ("countryid", "provinceid", "chn_name", "eng_name", )
    autocomplete_fields = ("countryid",)
@admin.register(Country)
class CityAdmin(admin.ModelAdmin):
    search_fields = ("chn_name", "eng_name",)
# admin.site.register(Country, CityAdmin)
admin.site.register(Province, ProvinceAdmin,)

注意外键字段代表的是定义了 ForeignKey

进阶之路：用国家关联城市，需要使用插件 django-smart-selects
