python, create dynamic html name values..

Question

i need a small help.. i am looping over objects which are in db and rendering all objects to template, so far so good. but what i want is that every rendered html name field should have different name so that i can refer to all of them latter. my code is this:

{% for p in products %}
      <input type="number" name="name1" value="{{p.arg1}}" size="12"/>
          <input type="number" name="name2" value="{{p-arg2}}" size="12"/>
{% endfor %}

but if i have 4 objects in DB, then i will have 8 rendered input fields in template, but all of them will have the "name" value as name1 and name2, is it possible to create 8 different names dynamically so that i can refer to all of them in my view again...

thanks

Use the forloop.counter variable

{% for p in products %}
    <input type="number" name="name-{{forloop.counter}}-arg1" value="{{p.arg1}}" size="12"/>
    <input type="number" name="name-{{forloop.counter}}-arg2" value="{{p.arg2}}" size="12"/>
{% endfor %}

The forloop.counter is 1-indexed. There is also the forloop.counter0 for indices starting with 0.

Are you sure though that django formsets isn't what you need?
