效果图：
一、Stark组件
stark/service/core_func.py
from django.urls import re_path
from django.shortcuts import HttpResponse, render class StarkHandler(object):
list_display = [] def __init__(self, model_class, prev):

tr_list.append(getattr(obj, field)) # 获取字段的值
body_list.append(tr_list) context = {

二、业务处理
web/stark.py
from stark.service.core_func import site, StarkHandler from web import models class DepartmentHandler(StarkHandler):
list_display = ['title'] class UserInfoHandler(StarkHandler):
list_display = ['name', 'age', 'email'] site.register(models.Department, DepartmentHandler)
site.register(models.UserInfo, UserInfoHandler)
