pythonDjango开发-自定义模板标签

1.在APP同级目录新建文件夹'templatetags' 并在文件夹下创建__init__.py和定义标签用的customer.py文件

2.在customer.py文件中定义自定义标签

from  django import template

from django.shortcuts import render,render_to_response

import datetime

register = template.Library()

@register.simple_tag

def get_current_time(format_string):

    return datetime.datetime.now().strftime(format_string)

@register.simple_tag

def get_html_test():

    return '<div>123123123131<div/>'

3.在需要调用的html页面 调用 先需要在页面引入 自定义模板文件{% load customer %},然后调用

<!DOCTYPE html>

{% load customer %}

<html lang="en">

  <head>

    <meta charset="utf-8">

    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <meta name="viewport" content="width=device-width, initial-scale=1">

    <meta name="description" content="">

    <meta name="author" content="">

    <link rel="icon" href="../../favicon.ico">

    <title>中文BBS</title>

    <!-- Bootstrap core CSS -->

    <link href="../../static/css/bootstrap.min.css" rel="stylesheet">

        <link href="../../static/css/customerize.css" rel="stylesheet">

<!-- Custom styles for this template -->

    <link href="../../static/css/navbar-static-top.css" rel="stylesheet">

  </head>

  <body>

     {% get_current_time "%Y-%m-%d %I:%M %p" as the_time %}

            <p>The time is {{ the_time }}.</p>

         <div>

             {% get_html_test %}

         </div>

    <!-- Bootstrap core JavaScript

</html>
