在 app01 下新建一个 templatetags 的文件夹，然后创建 myfilter.py 文件
这个 templatetags 名字是固定的，myfilter 是自己起的
myfilter.py：
from django import template
register = template.Library()
@register.filter(name="sleep") # name 是 html 中的过滤器名
def sleep(arg):
return "%s is sleep" %arg
views.py：
from django.shortcuts import render, redirect, HttpResponse
from app01 import models
# Filter 测试
def filter_test(request):
name = "Jack"
return render(request, "filter_test.html", {"name": name})
filter_test.html：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Filter 测试</title>
</head>
<body>
<!-- 这里需要导入自定义的 filter -->
{% load myfilter %}
{{ name|sleep }}
</body>
</html>
运行结果：
myfilter.py：
from django import template
register = template.Library()
@register.filter(name="sleep")
def sleep(arg):
return "%s is sleep" %arg
@register.filter(name="eat")
def eat(arg, arg1):
return "%s is eating %s" %(arg, arg1)
filter_test.html：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Filter 测试</title>
</head>
<body>
{% load myfilter %}
{{ name|sleep }}
<br>
{{ name|eat:"meat" }}
</body>
</html>
运行结果：
