Django - 您是否忘记注册或加载此标记？
我已经创建了一个我想要使用的自定义标记，但Django似乎无法找到它。我的templatetags目录设置如下：
pygmentize.py
from pygments import highlight
from pygments.lexers import get_lexer_by_name
from django import template
from pygments.formatters.other import NullFormatter
register = template.Library()
@register.tag(name='code')
def do_code(parser,token):
code = token.split_contents()[-1]
nodelist = parser.parse(('endcode',))
parser.delete_first_token()
return CodeNode(code,nodelist)
class CodeNode(template.Node):
def __init__(self,lang,code):
self.lang = lang
self.nodelist = code
def render(self,context):
code = self.nodelist.render(context)
lexer = get_lexer_by_name('python')
return highlight(code,lexer,NullFormatter())
我正在尝试使用此标记在gameprofile.html中呈现代码。
gameprofile.html
(% load pygmentize %}
{% block content %}
<title>{% block title %} | {{ game.title }}{% endblock %}</title>
<div id="gamecodecontainer">
{% code %}
{{game.code}}
{% endcode %}
</div>
{% endblock content %}
当我导航到gameprofile.html时，出现错误：
第23行的无效广告代码：＆＃39;代码＆＃39;，预期＆＃39; endblock＆＃39;。您是否忘记注册或加载此标记？

{% load games_tags %}
在顶部而不是pygmentize？
答案 1 :(得分：6)
错误在此行：(% load pygmentize %}，无效标记。
将其更改为{% load pygmentize %}
答案 2 :(得分：2)
我有同样的问题，这是我如何解决它。在this very excellent Django tutorial的第一部分之后，我做了以下内容：
- 执行：
python manage.py startapp new_app创建一个新的Django应用
- 修改
settings.py文件，将以下内容添加到INSTALLED_APPS列表中：'new_app', - 将新模块添加到名为
new_app的{{1}}包中。 - 在Django HTML模板中，将以下内容添加到文件顶部，但在
new_app_tags之后：{% extends 'base_template_name.html' %} - 在
{% load new_app_tags %}模块文件中，创建自定义模板标记（见下文）。 - 在相同的Django HTML模板中，从上面的第4步开始，使用你的闪亮新自定义标记：
new_app_tags - 庆祝！
上述第5步的例子：
{% multiply_by_two | "5.0" %}答案 3 :(得分：2)

并且它起作用了。因此，在您的情况下，如果您尝试从基本模板加载 {% load static %}，您只需要像这样添加它：
gameprofile.html答案 4 :(得分：1)
对于Django 2.2及更高版本，您必须先在html模板中加载 staticfiles ，然后再使用 static 关键字
{% load staticfiles %}
<link rel="stylesheet" href="{% static 'css/bootstrap.min.css' %}">
还必须检查是否在 setting.py
中定义了 STATIC_URL最后确保静态文件存在于定义的文件夹中
答案 5 :(得分：0)
包含自定义标记的应用必须位于INSTALLED_APPS中。那么您确定您的目录位于INSTALLED_APPS吗？
包含自定义标记的应用必须位于
INSTALLED_APPS，才能使{% load %}代码生效。这是一个安全功能：它允许您在单个主机上托管许多模板库的Python代码，而无需为每个Django安装启用所有模板库。
答案 6 :(得分：0)
在gameprofile.html中，请将标签{% endblock content %}更改为{% endblock %}，然后它将起作用，否则django将不会加载 endblock 并给出错误消息。
