Django无法加载模板标签 [英] Django could not load template tag
问题描述
templatetags
文件夹,并在名为 posts.py
的文件中创建了一个以下代码; from django.template import Library,Node
from advancedviews.models import Post
register = Library()
class AllPost(Node):
def render(self,context):
context ['all_posts'] = Post.objects.all()
return '
def get_all_posts(解析器,令牌):
返回AllPost()
get_all_posts = register.tag(get_all_posts)
现在,我尝试在我的模板中加载这个模板标签;
{%load get_all_posts%}
但这给我错误,'get_all_posts '不是有效的标签库:没有找到模板库get_all_posts,尝试django.templatetags.get_all_posts,django.contrib.admin.templatetags.get_all_posts
这个t的错误是什么?
使用加载
使用图书馆的名称,而不是标签 - 所以帖子
在你的情况下。
(我假设你在templateatetags目录中还有一个空白的 __ init __。py
,应用程序在 INSTALLED_APPS
中)
I have created a templatetags
folder inside my application and inside a file named posts.py
, I have written the following code;
from django.template import Library, Node
from advancedviews.models import Post
register = Library()
class AllPost(Node):
def render(self,context):
context['all_posts'] = Post.objects.all()
return ''
def get_all_posts(parser,token):
return AllPost()
get_all_posts = register.tag(get_all_posts)
Now, I try to load this template tag inside my template;
{% load get_all_posts %}
But this gives me with error, 'get_all_posts' is not a valid tag library: Template library get_all_posts not found, tried django.templatetags.get_all_posts,django.contrib.admin.templatetags.get_all_posts
What is the error in this template or have I missed something here.
With load
you need to use the name of the library, not the tag - so posts
in your case.
(I assume you also have a blank __init__.py
in the templatetags directory, and that the application is in INSTALLED_APPS
).
