一、需求
仿照django的admin，开发自己的stark组件。实现类似数据库客户端的功能，对数据进行增删改查。
二、实现
1、在settings配置中分别注册自己生成的app
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'crm.apps.CrmConfig',
"stark.apps.StarkConfig"
]
注：python manage.py startapp app01 创建新项目
2、在app01的models文件中创建数据类

数据库生成数据
python manage.py makemigrations python manage.py migrate
3、扫描(加载)每一个app下的stark.py
在app01创建一个stark.py文件，在项目启动时扫描每个app下的stark.py文件并执行
即在stark的apps.py中配置
from django.apps import AppConfig
from django.utils.module_loading import autodiscover_modules
class StarkConfig(AppConfig):
name = 'stark'
def ready(self):
autodiscover_modules('stark') #自动扫描
4、注册
仿照admin设置相关类，首先创建下面的文件
在执行admin.py文件时我们发现其实第一步就是导入admin，导入时通过单例模式生成了一个site对象，现在我们也来写一个类，生成一个单例对象
class StarkSite(object):
def __init__(self):
self._registry = {}
site = StarkSite()
在app01stark.py文件中导入
from stark.service.stark import site
这样我们也就得到了一个单例对象site，在注册时admin使用的是site对象的register方法，我们也学着他写一个register方法
class StarkSite(object):
def __init__(self):
self._registry={}
def register(self,model,modle_stark=None):
if not modle_stark:
modle_stark=ModelStark
self._registry[model]=modle_stark(model)
site = StarkSite()
这个方法的本质其实就是往self._registry这个字典中添加键值对，键就是我们的数据类(如Book类)，值是一个类的对象，这个类就是我们要创建的第二个类，样式类
class ModelStark(object):
def __init__(self, model, site):
self.model = model
self.site = site
self.model指的是什么？ 就是用户访问的model
通过这个类我们控制页面展示的内容和样式
做完这几步我们就可以在app01的stark.py文件中开始注册了
#app01 from stark.service.stark import site from .models import * site.register(UserInfo,UserInfoConfig) site.register(Blog) site.register(Article) site.register(Category) site.register(Tag)
注册完成后，我们的site._registry字典中就有了我们注册类对应的键值对，接下来就要配置url了
