def ready(self):

    autodiscover_modules('stark')

　　

class StarkSite(object):

　　def __init__(self, name='admin'):

　　　　self._registry = {} #记录注册的model类

　　def register(self, model, admin_class=None, **options):

　　　　if not admin_class:

　　　　admin_class = ModelStark # 配置类

　　　　self._registry[model] = admin_class(model)

　　

#一级路由代码

def get_urls(self):

    temp = []

    for model_class, config_obj in self._registry.items():

        print("===>", model_class, config_obj)

        model_name = model_class._meta.model_name

        app_label = model_class._meta.app_label

        print("===>", app_label, model_name)

        temp.append(url(r'^%s/%s/' % (app_label, model_name),config_obj.urls))

　　

def get_urls(self):

    temp=[

        url("^$",self.list_view,name="%s_%s_list"%(self.app_model_name)),

        url("^add/$",self.add_view,name="%s_%s_add"%(self.app_model_name)),

        url("^(\d+)/change/$",self.change_view,name="%s_%s_change"%            (self.app_model_name)),

        url("^(\d+)/delete/$",self.delete_view,name="%s_%s_delete"%(self.app_model_name)),

]

        temp.extend(self.extra_urls())

        return temp

@property                               #此装饰器的作用是让方法变成可以像属性一样调用

def urls(self):

　　   return self.get_urls(),None,None

至于增删改查视图中的方法就步过介绍了，自定义admin组件的基本逻辑就是这样
