《Django 5 By Example》阅读笔记:p54-p75
《Django 5 By Example》学习第3天,p54-p75总结,总计22页。
一、技术总结
1.分页
(1)分页:Paginator
(2)页数不存在处理: EmptyPage, PageNotAnInteger
2.class-based views(类视图)
(1)为什么使用类视图?
1)Organize code related to HTTP methods, such as GET, POST, or PUT, in separate methods, instead of using conditional branching(使用类视图可以根据http请求方法来组织视图,而不是条件判断)。
2)Use multiple inheritance to create reusable view classes (also known as mixins)(使用多继承来实现视图复用)。
3.forms(表单)
主要是两类:Form, ModelForm。不过表单在实际的开发中用得较少。
二、英语总结(生词:2)
1.canonical
p55, Using canonical URLs for models.
(1)canon
c. a rule, principle or law.
(2)canonical
adj. according to a rule.
2.facilitate
(1)facilitate: facili(“easy to do”),
vt. to make sth easier(促进). p76, To facilitate the separation of configuration from code, we are going to use python-decouple.
三、其它
今天没有什么想说的。
