类视图
代码越少越好
永远不要重复代码
View应当只包含呈现逻辑, 不应包括业务逻辑
保持view逻辑清晰简单
不要将CBVs用作403, 404, 500的错误处理程序
保持mixin简单明了
Django自身提供的View永远在最右边
mixin依次在以上view的左边
mixin永远继承自Python的object类型
View 基本View 可以在任何时候使用 见后面详细介绍 RedirectView 重新定向到其他URL 将访问"/log-in/"的用户重新定向到"/login/"TemplateView 显示Django 模板 一般网站中使用模板显示的页 ListView 显示对象列表 文章列表页 DetailView 显示对象详情 文章详细页 FormView 提交From 网站联系我们或emai订阅form CreateView 创建对象 创建新文章页 UpdateView 更新对象 修改文章页 DeleteView 删除对象 删除文章页 Generic date views 显示一段时间内的对象 按时间归类的博客
