- 基本使用
- 母版
- 导入include
- 函数 - > 不用加() 自动执行
- 模版自定义函数：
- simple_filter
- 最多两个参数 {{ name2|my_upper2:’ hello!’ }}
- simple_tag
- 参数个数限制 {% my_upper3 name2 ‘ddd’ ‘hello!’ ‘autumn’ %}
- simple_filter 可以做条件判断，simple_tag不行

</html>自定义simple_tag 过程
- a、在app中创建templatetags模块
b、创建任意 .py 文件，如：xx.py
#!/usr/bin/env python #coding:utf-8 from django import template from django.utils.safestring import mark_safe register = template.Library() @register.simple_tag def my_simple_time(v1,v2,v3): return v1 + v2 + v3 @register.simple_tag def my_input(id,arg): result = "<input type='text' id='%s' class='%s' />" %(id,arg,) return mark_safe(result)c、在使用自定义simple_tag的html文件中导入之前创建的 xx.py 文件名
{% load xx %}d、使用simple_tag
{% my_simple_time 1 2 3%} {% my_input 'id_username' 'hide'%}e、在settings中配置当前app，不然django无法找到自定义的simple_tag
