Jinja2“ as”标签不起作用？

Question

I have this code in index.html :

{% url 'cronjobs:remove-job' as remove_job_url %}

And I want to use it further down in the same HTML file multiple times, eg:

<a href="{{ remove_job_url }}">Remove job</a>

According to this answer , I think I got everything right. However, the variable remove_job_url is null. Nothing is printed to the anchor tag.

I have loaded the Jinja2 into my settings.py -> TEMPLATES as described in the documentation , yet it does not seem to work. Any ideas what might be wrong?

(this also happens when I use the {% trans ... as trans_var %} tag, the trans_var is again - empty)

You are trying to use Django template syntax in a Jinja2 template. The template syntax is related, but no the same . You need to use Jinja2 assignment syntax instead.

{% set remove_job_url = url('cronjobs:remove-job') %}

Note the url() call . See the Url reversing section of the Django-jinja integration documentation.
