1 普通正则
2 分组正则
url(r'/blog/(\d+)/(\d+)',views.blog) blog(request,arq1,arq2) 按照位置传参
3 分组命名
url(r'/blog/(?P<year>\d+)/(?P<month>\d+)',views.blog) blog(request,year,month)
4 用name 指定别名
url(r'/blog/(?P<year>\d+)/(?P<month>\d+)',views.blog,name ='blog') blog(request,year,month
涉及到了反向解析URL
4-1 在html里面:{% url 'blog' 2012 12%}
4-2from django.urls import reverse reverse ('blog',arg=(2013,11))
5 用namespace 指定命名空间
url(r'/app01/',inclue(app01.urls,namespace='app01))
涉及到了反向解析URL
5-1 HTML 里面{% url 'app01:blog' 2012 11%}
5-22 在views reverse('app01:blog' ,arg=(2010,33))
--------------
通过get取值 和通关过分组取值的用法和对比
1 HTML 里面{% url 'app01:blog' 2012 11%}
2 在views reverse('app01:blog' ,arg=(2010,33))
要在Django Console 打印出有sq语句 在django 项目的配置信息中加上这个日志 而且引用
models 中插入这句在定义的类的下面的缩进行里 这样打印出来的结果对象就会是实际的内容
def __str__(self):
return '{}{}'.format(self.cname,self.first_day)
单表查询的增删改查
单表查询的API 介绍 共13条

1 all():全部 2 filter():过滤 3 exclude():不包括
4 value()值 5value_list() 值的列表 6 order_by() 排序正序
7 reverse() 反转 8 distinct() 去重
