我在mytag.py文件中有mytag的标签定义。当我使用带有settings.py和INSTALLED_APPS的Django项目时,这很好用 - 我将'myapp'附加到列表中并将mytag.py放在myapp / templatetags中。
现在我正在使用django.conf.settings.configure,我没有带有templatetags子目录的模块 - 如何加载mytag.py?
更新
我现在尝试使用带有templatetags目录的模块,但我无法让它工作。这是我的设置:
文件:
__init.py__
__init__.py
这是相关代码:
# test.py
from django.template import Template, Context
from django.conf import settings
from mostlystatic.processors.mostlystaticprocessor import MostlystaticProcessor
from mostlystatic.stuff import DebugLogger
import sys
sys.path.append("~/")
settings.configure(
DEBUG=True,
TEMPLATE_DEBUG = True,
INSTALLED_APPS = ("myapp",)
)
t = Template(open("test.html").read())
c = Context({})
content = t.render(c)
print content
# test.html
{% load mytag %}
# mytag.py (doesn't load)
from classytags.arguments import Argument
from classytags.core import Tag, Options
from django import template
register = template.Library()
class MyTag(Tag):
name="mytag"
def render_tag(self, context:
return "test"
register.tag(MyTag)
当我运行test.py时,我收到此消息:
Traceback (most recent call last):
File "test.py", line 16, in <module>
t = Template(open("test.html").read())
File "/Library/Python/2.7/site-packages/django/template/base.py", line 125, in __init__
self.nodelist = compile_string(template_string, origin)
File "/Library/Python/2.7/site-packages/django/template/base.py", line 153, in compile_string
return parser.parse()
File "/Library/Python/2.7/site-packages/django/template/base.py", line 270, in parse
compiled_result = compile_func(self, token)
File "/Library/Python/2.7/site-packages/django/template/defaulttags.py", line 1033, in load
(taglib, e))
django.template.base.TemplateSyntaxError: 'mytag' is not a valid tag library: Template library mytag not found, tried django.templatetags.mytag
答案 0 :(得分:3)
最简单的方法是创建一个带有templatetags
子目录的模块,并在配置设置时将该模块包含在INSTALLED_APPS
中。
任何其他方法都涉及与Django内部的摔跤。
如果您的脚本不起作用,请尝试将其拆分为下面非常简单的内容,然后重新构建它。
from django.conf import settings
settings.configure(INSTALLED_APPS=('my_app',))
from django.template import Template
# my_tags does not exist, but the error shows that it is
# searching my_app's template tag directory
Template.render("{% load my_tags %}")
TemplateSyntaxError: 'my_tags' is not a valid tag library: Template library my_tags not found, tried django.templatetags.my_tags, my_app.templatetags.my_tags
