i getting below error "

noreversematch @ /member/when/ reverse 'media' arguments '()' , keyword arguments '{}' not found." 

in following line in views.py

redirect_to = request.post.get('next',                 reverse('media')             ) 

template is

<form action="/member/when/" method="post"> {% csrf_token %}                    {{ form.manual_date_time }}             <p id=ir-nextbutn><a href="{% url incident.views.media %}">             {% include "buttons/next.html" %}</form>  attributeerror @ /member/when/ 'function' object has no attribute 'find' 

you need name urls

url(r'^when/$', 'when', name='when'), url(r'^media/$', 'media', name='media'), url(r'^followup/$', 'followup', name='followup'), 

or avoid conflicting url names can prefix app's name.

url(r'^when/$', 'when', name='app_name_when'), url(r'^media/$', 'media', name='app_name_media'), url(r'^followup/$', 'followup', name='app_name_followup'), 

obviously replace app_name actual name of app.

you can update template

{% url incident.views.media %} # changes to: {% url 'media' %}
