Django FormWizard with different templates - django

Question

I am trying to use FormWizard to make a registration for new users. Because in some steps I would need to use js,formsets, and photos, I decided to make a different template for each step. But then I got an error :
ValidationError at /registration_steps
[u'\u0414\u0430\u043d\u043d\u044b\u0435 ManagementForm \u043e\u0442\u0441\u0443\u0442\u0441\u0442\u0432\u0443\u044e\u0442 \u0438\u043b\u0438 \u0431\u044b\u043b\u0438 \u0438\u0441\u043a\u0430\u0436\u0435\u043d\u044b.']

As form wizard complains about the missing management form, the problem seems to be related to nested formsets. Make your relevant template section look like:
<table>
{{ wizard.management_form }}
{% if wizard.form.forms %}
{{ wizard.form.management_form }}
{% for form in wizard.form.forms %}
{{ form }}
{% endfor %}
{% else %}
{{ wizard.form }}
{% endif %}
</table>
