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..

I don't think it's intended you should alter data in your templates. For in your specific case, you could instead use the forloop.counter
variable.
For example:
{% for op in options %}
{{op.choices}}<input type="radio" name="template" id="template{{forloop.counter}}" value="template{{forloop.counter}}"/>
{% endfor %}
Also note that I added that number to the id
attributes of the <input />
tag. Otherwise you'll have multiple inputs with the same id.
EDIT: I didn't note that it was a radio input. You could of course have the same name for each <input type="radio" />
.
You explicitly can't do that in a template. Variable assignment is not allowed.
However if all you want is a counter in your loop, you just need to use {{ forloop.counter }}
.
