1、新建Django项目--新建app:app01和stark--在settings中配置app和数据库--在models.py中新建模型表--完成数据库迁移

2、在stark下的apps.py中：

from django.apps import AppConfigfrom django.utils.module_loading import autodiscover_modulesclass StarkConfig(AppConfig):    name = 'stark'    def ready(self):        autodiscover_modules('stark')  # 在程序启动后、url路由分配之前去找到叫stark的app

3、在settings中配置stark：

4、在app01下新建stark.py文件，完成模型表注册：

from stark.service.stark import *from django.utils.safestring import mark_safefrom django.urls import reversefrom .models import *class UserInfoConfig(ModelStark):    def edit(self, data_obj):        """编辑"""        model_name = self.model._meta.model_name  # 表名        app_label = self.model._meta.app_label  # app名        _url = reverse("%s_%s_edit" % (app_label, model_name), args=(data_obj.pk,))  # 反向解析 拿到url        return mark_safe("编辑" % _url)  # 防止转义    def checkbox(self, data_obj):        """每条记录前面插入一个选择框"""        return mark_safe("")    list_display = [checkbox, "name", "age", edit]class BookConfig(ModelStark):    list_display = ["title", "price", "pub_date"]site.register(UserInfo, UserInfoConfig)site.register(Book, BookConfig)print("_registry:", site._registry)"""函数：函数中有多少个参数，就要传递多少各参数，不存在自动传参方法：自动将调用对象作为第一个参数进行传递"""

5、在stark下新建包service--service下新建stark.py文件：

from django.conf.urls import urlfrom django.shortcuts import HttpResponse, renderclass ModelStark(object):    list_display = []    def __init__(self, model, site):        self.model = model  # 用户当前访问的模型表        self.site = site    def add(self, request):        """新增记录"""        return HttpResponse("add")    def delete(self, request, delete_id):        """删除记录"""        return HttpResponse("delete")    def edit(self, request, edit_id):        """编辑"""        return HttpResponse("edit")    def show(self, request):        """查看"""        data_list = self.model.objects.all()  # 获取数据        new_data_list = []        if self.list_display:            for data_obj in data_list:  # 数据对象                temp = []                for field in self.list_display:  # 字段名                    if callable(field):  # 判断是否为函数                        val = field(self, data_obj)                    else:                        val = getattr(data_obj, field)  # 通过反射获取字段对应的数据                    temp.append(val)                new_data_list.append(temp)        return render(request, "listInfo.html", locals())    def get_method(self):        """增删改查url"""        method_list = []        model_name = self.model._meta.model_name        app_label = self.model._meta.app_label        method_list.append(url(r'^add/', self.add, name="%s_%s_add" % (app_label, model_name)))        method_list.append(url(r'^(\d+)/delete/', self.delete, name="%s_%s_delete" % (app_label, model_name)))        method_list.append(url(r'^(\d+)/edit/', self.edit, name="%s_%s_edit" % (app_label, model_name)))        method_list.append(url(r'^$', self.show, name="%s_%s_show" % (app_label, model_name)))        return method_list    @property    def urls2(self):        return self.get_method(), None, Noneclass StarkSite(object):    def __init__(self):        self._registry = {}    def register(self, model, stark_class=None):        if not stark_class:            stark_class = ModelStark        self._registry[model] = stark_class(model, self)    def get_urls(self):        """拼接url"""        urls_list = []        for model, stark_class_obj in self._registry.items():            model_name = model._meta.model_name  # 模型表            app_label = model._meta.app_label  # app名称            print(model_name, app_label)            # 添加url            urls_list.append(url(r'^%s/%s/' % (app_label, model_name), stark_class_obj.urls2))            """           url(r'^app01/userinfo/', UserInfoConfig(UserInfo).urls2),            url(r'^app01/book/', ModelStark(Book).urls2),            """        return urls_list    @property    def urls(self):        return self.get_urls(), None, Nonesite = StarkSite()

6、templates下新建模板

7、全局urls.py：

from django.contrib import adminfrom django.urls import path, includefrom django.conf.urls import urlfrom stark.service import starkurlpatterns = [    path('admin/', admin.site.urls),    # 自定义stark组件    url('^stark/', stark.site.urls),]"""admin源码：1、注册    admin.py          admin.site.register()2、url设计    在ModelStark中：        self.model :用户当前访问的模型表        查看页面：        表头        表数据        search        actions        分页        filter        增删改(modelForm)        pop功能        作业：        访问任何模型表时都有编辑、删除、选择框        如果用户没有配置的list_display，如何显示数据"""
