问题
I am getting the following errors in a django app:
TemplateSyntaxError at /
'markup' is not a valid tag library: Template library markup not found, tried django.templatetags.markup,django.contrib.admin.templatetags.markup
I have tried to following the solutions form this website which suggests that that 'django.contrib.markup' is missing from the INSTALLED_APPS list, but I already have it there.
I can import markdown from python manage.py shell so it is installed and is in the path.
I am using Django 1.3.
Here is the template:
{% load markup %}
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
...
I just tried it again, and it works. Odd. I tried restarting the server before submitting the question, but I am not sure what is different now.
回答1:
Try calling render_to_response from python manage.py shell on the template in question, and please give a clip of the template file in question.
Fixed itself? Spooky. I hate those "fixes" because there's no guarantee that it won't break again or that the same "fix" will work again.
The only things I can think of there are:
- Something had the old version cached
- There was an old .pyc file laying around
- Your server was trying to be clever
- WSGI didn't reload the code or templates after you changed it
