Still quite useful, this is a improved and evolved version of the original implementation of the django-uni-form project.
Add {% load uni_form_filters %} to the template that calls your form.
Append your form call with the as_uni_form filter:
{{ my_form|as_uni_form }}
Add the class of ‘uniForm’ to your form. Example:
<form action="" method="post" class="uniForm">
Refresh and enjoy!
To see this more clearly:
{% extends "uni_form" %}
<form method="post" class="uniForm">
{{ my_form|as_uni_form }}
</form>
