Django admin配置list_filter报错people__type非有效字段问题问询

问题原因 #

• list_filter 属性缩进错误，当前代码中它定义在 PeopleAdmin 类的外部，不属于Admin类的配置属性，Django无法识别这是你给People后台配置的筛选规则。
• list_filter 的值配置错误，你当前是给People模型本身配置Admin后台，筛选自身字段直接写字段名即可，people__type 是关联模型跨表查询的写法，不适用于当前场景。

修正后的admin.py代码 #

from django.contrib import admin
from django.db import models
from .models import *
from tinymce.widgets import TinyMCE

# Register your models here.
class PeopleAdmin(admin.ModelAdmin):
    fieldsets = [
        ("Type", {"fields": ["type"]}),
        ("Information", {"fields": ["people_name",
                                    "people_surname",
                                    "people_phone_number",
                                    "people_email",
                                    "people_occupation",
                                    "people_revenue"]}),
        ("URL", {"fields": ["people_slug"]}),
    ]
    # 缩进移到类内部，直接使用字段名type
    list_filter = ('type',)

admin.site.register(People, PeopleAdmin)
