[英]Django: Create custom template tag -> ImportError
I'm sorry to ask this again, but I tried several solutions from stack overflow and some tutorials and I couldn't create a custom template tag yet. 很抱歉再次问到这个问题,但是我尝试了堆栈溢出的一些解决方案和一些教程,但还无法创建自定义模板标签。 All I get is ImportError: No module named test_tag
when I try to start the server via python manage.py runserver
. 我得到的只是ImportError: No module named test_tag
当我尝试通过python manage.py runserver
启动服务器时, ImportError: No module named test_tag
。
I created a very basic template tag (found here: django templatetag? ) like so: 我创建了一个非常基本的模板标记(在这里找到: django templatetag? ),如下所示:
My folder structure: 我的文件夹结构:
demo
manage.py
test
__init__.py
settings.py
urls.py
...
templatetags
__init__.py
test_tag.py
test_tag.py: test_tag.py:
from django import template
register = template.Library()
@register.simple_tag
def test_tag(input):
if "foo" == input:
return "foo"
if "bar" == input:
return "bar"
if "baz" == input:
return "baz"
return ""
index.html: index.html的:
{% load test_tag %}
<html>
<head>
...
</head>
<body>
{% cms_toolbar %}
{% foobarbaz "bar" %}
{% foobarbaz "elephant" %}
{% foobarbaz "foo" %}
</body>
</html>
and my settings.py: 和我的settings.py:
INSTALLED_APPS = (
...
'test_tag',
...
)
Please let me know if you need further information from my settings.py and what I did wrong so I can't even start my server. 如果您需要我settings.py中的更多信息以及我做错了什么,请甚至告诉我,我什至无法启动服务器。 (If I delete 'test_tag' from installed apps I can start the server but I get the error that test_tag is not known, of course). (如果我从已安装的应用程序中删除“ test_tag”,则可以启动服务器,但是我得到的错误是,当然不知道test_tag)。
Thanks 谢谢
The templatetags
folder should be within an application. templatetags
文件夹应位于应用程序内。
You project tree should look something like: 您的项目树应类似于:
demo
manage.py
test
__init__.py
settings.py
urls.py
test_app
__init__.py
models.py
tests.py
views.py
templatetags
__init__.py
test_tag.py
Then, add test_app
to INSTALLED_APPS
, and remove test_tag
from there. 然后,将test_app
添加到INSTALLED_APPS
,然后从其中删除test_tag
。
