效果图：
新增函数
def get_choice_text(title, field) 闭包函数，显示choice字段 def inner(self, obj=None, is_header=None) def display_edit(self, obj=None, is_header=None) 显示编辑 def display_delete(self, obj=None, is_header=None) 显示删除
一、Model
web/models.py
class UserInfo(models.Model): """ 用户表 """ MALE = 1 FEMALE = 2 GENDER_CHOICES = ( (MALE, '男'), (FEMALE, '女'), ) CLASSES_CHOICES = ( (1, 'python一班'), (2, 'python二班'), ) name = models.CharField(verbose_name='姓名', max_length=32) age = models.CharField(verbose_name='年龄', max_length=32) email = models.CharField(verbose_name='邮箱', max_length=32) gender = models.PositiveIntegerField(verbose_name='性别', choices=GENDER_CHOICES, default=MALE) classes = models.PositiveIntegerField(verbose_name='班级', choices=CLASSES_CHOICES, default=1) department = models.ForeignKey(verbose_name='部门', to='Department', on_delete=models.CASCADE) def __str__(self): return self.name
二、stark
stark/service/core_func.py

三、业务处理
web/stark.py
from stark.service.core_func import site, StarkHandler, get_choice_textfrom web import modelsclass DepartmentHandler(StarkHandler): list_display = ['title']class UserInfoHandler(StarkHandler): list_display = [ 'name', get_choice_text('性别', 'gender'), get_choice_text('班级', 'classes'), 'age', 'email', 'department', StarkHandler.display_edit, StarkHandler.display_delete, ]site.register(models.Department, DepartmentHandler) site.register(models.UserInfo, UserInfoHandler)
四、引入静态文件
引入了bootstrap
stark/templates/layout.html
{% load staticfiles %} Strak组件 {% block css %}{% endblock %} {% block content %} {% endblock %} {% block js %} {% endblock %} 
stark/templates/stark/data_list.html
{% extends 'layout.html' %}{% block content %} {% for item in header_list %} { { item }} {% endfor %} {% for row in body_list %} {% for ele in row %} { { ele }} {% endfor %} {% endfor %}
{% endblock content %}
