当 ForeignKey 数据过多，手动在后台添加时不方便找到自己的想要数据，遂想要一个可以搜索检索数据功能。

With this you can use the autocomplete_fields on a foreignkey field on your source admin class and as before set the search_fields on the target admin class.

配置 admin

class AnchorBindAgentAdmin(admin.ModelAdmin):
    list_display = ["agent", "anchor", "proportion", "start_time", "end_time", "create_time"]
    list_display_links = ["agent", "anchor", "proportion", "start_time", "end_time", "create_time"]
    list_filter = ["agent", "anchor", "start_time", "end_time"]
    list_per_page = 20  # 每页数量
    readonly_fields = ["start_time"]
    autocomplete_fields = ["anchor"]  # 带有搜索框的外键选择框
