Actually I've used on my model But when my RitchTextField attribute is used on a template it render the raw html value.
For example: If the user write a texte like "This is the project one" on django admin.
On my custom template it shows "This is the <strong>project</strong> one"
This is my template:
{% extends "base.html" %}
{% load i18n %}
{% block meta_title %}{% trans "Home" %}{% endblock %}
{% block title %}{% trans "Home" %}{% endblock %}
{% load pages_tags %}
{% block main %}
<div class="page-header">
<h3>{{project.title}}</h3>
</div>
{{project.description}}
{% endblock %}
