无法解析剩余的 Django [英] Could not parse the remainder Django

问题描述

我一直在尝试编写一个自定义模板标签来缩短链接，我已经附上了下面的代码和错误.我试图查看 Django 提供的文档，但看不出我做错了什么.

I've been trying to write a custom template tag to shorten links with bitly, I've attached the code and error I've been getting below. I've tried to look into the documentation provided by Django but cannot see what it is that I am doing wrong.

我已将我的模板标签置于以下布局中:

I've put my templatetag in the following layout:

scribbler/
    models.py
    templatetags/
        __init__.py
        shortenlink.py
    views.py

我编写的自定义标记文件:

the custom tag file that I've written:

from django import template
from django.conf import settings
from urllib import urlencode
from urllib2 import urlopen

register = template.Library()

@register.simple_tag
def bitlyshort(the_url):
    endpoint = 'https://api-ssl.bitly.com/v3/shorten?access_token={0}&longUrl={1}&format=txt'
    req = urlencode(endpoint.format(settings.ACCESS_KEY, the_url))
    return urlopen(req).read()

使用模板标签的模板部分:

part of the template that uses the template tag:

{% load shortenlink %}
<p>{{ bitlyshort "http://www.google.com" }}</p>

推荐答案

错误在这一行:

<p>{{ bitlyshort "http://www.google.com" }}</p>

模板标签使用{% ... %}(模板filters使用{{ ... }}).试试:

Template tags use {% ... %} (template filters use {{ ... }}). Try:

<p>{% bitlyshort "http://www.google.com" %}</p>
