模板语法

1.深度查询：

def index(request):
    name = "root"
    age = 13
    sex = True
    lve = ["swimming","shopping","coding",]
    bookinfo = {"id":10,"price":9.0}

    return render(request,"index.html",locals())

//locals()代表传入的所有变量
#模板代码template/index.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<a> hi {{name}}</a> //普通变量取值
<a>lve :{{lve.1}}</a>//通过局点符取出列表中的第二个元素
<a>lve :{{bookinfo.id}}</a> //通过句点符取出字典中id的 值
</body>
</html>

//句点符表示深度查询

 2.嵌套，继承

{% include "模版文件名" %}#模版嵌入


{% extends "base.html" %}#模板继承

    def index（request):
        """ 模版语法"""
        return render(request,"index.html",locals())
#子模版部分 templates/index.html
{% extends "base.html"%}
......内容
{{block.super}}#继承父盒子中的默认数据
{% endblock %}
#必须放在最上面


#父模版 templates/base.html
.......内容

    [% block title %]
    <title>title<tetle/>
    {% endblock %}
............内容
