10.21CRM项目(01)

2018-10-21 13:35:19

crm第一天!放上初始源码!

后面等做完最后一天的手放上所有源码!

越努力越幸运!永远不要高估自己!

注意 多层for循环的时候,切记,不要名字重复!啦!!!!!不要名字重复!啦!!!!!不要名字重复!啦!!!!!不要名字重复!啦!!!!!

注意语法:

如果在某个model里面定义有元组

如果想取到该字段元组后面的值比如"男","女"

则需要调用

obj.get_gender_display()

若是用getattr()的方法仅仅只能取到前面的"1",

2. 在原有的strak系统中扩展某个表下的url
　　2.1 在该表的配置类中写入一个定义url的方法(stark的ModelStrak类中也得有这个方法,以为都是父类提供接口,子类重写方法)
　　crm/stark.py

    def extra_url(self):

        temp=[]

        temp.append(url(r"cancel_course/(\d+)/(\d+)",self.cancel_course))

        return temp

　　2.2父类的代码

　　server/stark.py

　　

    def extra_url(self):

        return []
　　

def get_urls_2(self):

    temp = []

    model_name=self.model._meta.model_name
    app_label=self.model._meta.app_label

    temp.append(url(r"^add/", self.add_view,name="%s_%s_add"%(app_label,model_name)))
    temp.append(url(r"^(\d+)/delete/", self.delete_view,name="%s_%s_delete"%(app_label,model_name)))
    temp.append(url(r"^(\d+)/change/", self.change_view,name="%s_%s_change"%(app_label,model_name)))
    temp.append(url(r"^$", self.list_view,name="%s_%s_list"%(app_label,model_name)))
　　
　　# 在这继承extra_url()的temp ,这样默认temp为空,其他的表的配置类没有写则无扩展的url,如果有的话则实现了扩展
    temp.extend(self.extra_url())

    return temp
