That is not possible using the standard template syntax which is
deliberately meant to be simple.
If you really want to do it you can either write a custom template tag
which in your case would take X.id as argument and return the correct
form field (the tmplate tag code can access the context and find the
form object). See the template_python doc for details.
However when I have needed to do this I simply add a item attribute to
each form field so in the template you can do:
{% for x in form %}
{{x.item.some_x_attr}}
{{x}}
{% endfor %}
To set up the item attr just do:
form = DynForm()
form.setFields(form_dict)
for x in y:
form.fields[x.id].item = x
Obviously if you do this a lot you would modify DynForm to do all the work.
