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>

    <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

    <!-- Placed at the end of the document so the pages load faster -->
    <script src="../../static/js/jquery.min.js"></script>
    <script src="../../static/js/bootstrap.min.js"></script>

  </body>
</html>
