Question

{% if posts %}
    {% for p in posts %}
        {{p|safe}}
    {% endfor %}
{% endif %}

I want this to render html but not javascript, what should I do?

Answer 1

There is no filter in django that can do what ou want: strip javascript and leave html.

You can create a custom template filter to do that:

from django import template
from django.template.defaultfilters import stringfilter
from django.utils.safestring import mark_safe
from django.utils.encoding import force_unicode
import re

register = template.Library()

@register.filter
@stringfilter
def stripjs(value):
    stripped = re.sub(r'<script(?:\s[^>]*)?(>(?:.(?!/script>))*</script>|/>)', \
                      '', force_unicode(value), flags=re.S)
    return mark_safe(stripped)

(Where to put template filters/tags: Custom template tags and filters/Code layout)

Brief explanation:

Create a folder named templatetags in your application folder. Add an empty file __init__.py (for it to be a package) and a module file that will contain the filter, my_filters.py. Copy the code in that file.

In the template file add (before any first use of the filter): {% load my_filters %}

Usage:

{% if posts %}
    {% for p in posts %}
        {{ p|stripjs }}
    {% endfor %}
{% endif %}
