CRM客户关系管理系统知识点总结

一、项目需求（使用PrecessOn）

二、models.py

三、开发中使用的相关技术：

　　Django\Bootstrap\Jquery等

四、项目各个功能的实现以及知识点：

1、自定义数据库表显示页面

  注解：

  enabled_admins ：register(model_class：表名,admin_class=None：表相关的类)

  model_class._meta.app_label：相当于models.Customer._meta.app_label  结果为：app名：'crm'

  　　model_class._meta.model_name：相当于models.Customer._meta.model_name 结果：'customer'

  models.Customer._meta.verbose_name获取表的中文名

  admin_class.model = model_class相当于models.Customer

  enabled_admins[model_class._meta.app_label][model_class._meta.model_name] = admin_class  实例化类 （CustomerAdmin）

  table_list:   table_list = king_admin.enabled_admins  当前已经注册的表， enabled_admins 中存的app、表名

  页面跳转的实现：
  <a href="{% url 'table_objs' app_name table_name %}">

  url(r'^(\w+)/(\w+)/$', views.display_table_objs,name="table_objs"),
  相当于：def table_objs((w+),(w+))的两个参数为app_name table_name
