CRM系统主要通过自定义stark组件来实现的(参照admin系统自定义):
STARK组件:
1 admin组件
1 如何使用admin
2 admin源码
3 创建自己的admin组件：stark
(1)当django启动时加载每一个app下的stark.py文件
from django.utils.module_loading import autodiscover_modules
autodiscover_modules('stark')
(2) 注册模型
基于模块单例模式：
func.py:
class A():
pass
a=A()
main.py:
from func import a
from func import a as b
a==b
stark组件的单例类：
class ModelStark(object):
list_display=["__str__"]
def __init__(self,model):
self.model=model
class StarkSite(object):
"""
stark组件的全局类
"""
def __init__(self):
self._registry = {}
# 1 模型类的注册功能
def register(self, model, admin_class=None):
# 设置配置类
admin_class=admin_class or ModelStark
self._registry[model] = admin_class(model)
site= StarkSite()
在某一个app下的stark.py文件下：
from .models import *
class BookConfig(ModelStark):
list_display=["title"]
site.register(Book,BookConfig)
site.register(Publish)
View Code
(3) 设计URL
语法：url或者path的分发
1 path("test1/",([
2 path('test02/', ([
3 path('test04/', views.test04),
4 path('test05/', views.test05),
5 ],None,None)),
6 path('test03/', views.test03),
7 ],None,None))

--添加，编辑 modelform组件
