Hey,
A filter would work better here if you can use one. The following
should work:
Defined as: @register.filter def encode_url(link_text): return
link_text.replace(' ', '_')
And in template: {% with state_url=flow.state.description|encode_url %}
<a href="{% url 'advance-flow' flow.id state_url %}">advance</a> {%
endwith %}
