All, How Can we increment a value like the following in django templates, {{ flag =0 }} {% for op in options %} {{op.choices}}<input type="radio" name="template" id="template" value="template{{flag++}}"/> {% endfor %} thanks..

For instance, given that I have pk of object from class A , I would like to do something like the following: {{ A.objects.get(pk=A_pk).name }} How can I do this?
