无法解析其余的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，但看不到我做错了什么。

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.

我已经将我的模板标签放在以下布局中：

I've put my templatetag in the following layout:

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

我写的自定义标签文件： / p>

shortenlink.py

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()

使用模板的模板的一部分e标签：

part of the template that uses the template tag:

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

错误

推荐答案

错误在这一行：

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

模板标签使用 {％... ％} （模板过滤器使用 {{...}} ）。尝试：

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

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