How to put comments in Django templates

Question

As answer by Miles, {% comment %}...{% endcomment %} is used for multi-line comments, but you can also comment out text on the same line like this:

{# some text #}

Comment tags are documented at https://docs.djangoproject.com/en/stable/ref/templates/builtins/#std:templatetag-comment

{% comment %} this is a comment {% endcomment %}

---

Single line comments are documented at https://docs.djangoproject.com/en/stable/topics/templates/#comments

{# this won't be rendered #}

Using the {# #} notation, like so:

{# Everything you see here is a comment. It won't show up in the HTML output. #}

In contrast to traditional html comments like this:

<!-- not so secret secrets -->

---

Django template comments are not rendered in the final html. So you can feel free to stuff implementation details in there like so:

Multi-line:

{% comment %}
    The other half of the flexbox is defined 
    in a different file `sidebar.html`
    as <div id="sidebar-main">.
{% endcomment %}

Single line:

{# jquery latest #}

{#
    beware, this won't be commented out... 
    actually renders as regular body text on the page
#}

I find single line comments especially helpful as placeholders for views that have not been created yet <a href="{% url 'view_name' %}".

Multiline comment in django templates use as follows ex: for .html etc.

{% comment %} All inside this tags are treated as comment {% endcomment %}

This way can be helpful if you want to comment some Django Template format Code.

{#% include 'file.html' %#} (Right Way)

Following code still executes if commented with HTML Comment.

<!-- {% include 'file.html' %} --> (Wrong Way)
