Django Templates: Form field name as variable?

Question

How can I make this loop to print form fields where XXXXXXXX is the value of ticket.id?

{% for ticket in zone.tickets %}
    {{ ticket.id }}: {{ form.ticket_count_XXXXXXXX }}
{% endfor %}

So the output to be something like this...

1: <input ... name="ticket_count_1">
10: <input ... name="ticket_count_10">
12: <input ... name="ticket_count_12">
3: <input ... name="ticket_count_3">

I like this way: stackoverflow.com/a/12307727/177293

You can't pass arguments in the django template, so no.

You'd need to implement a template tag (more of a pain) or filter, or make the association from ticket to formfield in your view (what I would recommend).

Since I don't actually know the relationship between ticket and your form fields, I can't tell what the best method is, but this would 'just work' based on the info you've provided.

# view
form = MyForm()
for ticket in zone.tickets:
    ticket.form_field = form['ticket_count_' + str(ticket.id)]

# template
{% for ticket in zone.tickets %}
    {{ ticket.id }} : {{ ticket.form_field }}
{% endfor %}

This looks like it will work "#ticket['form_field'] = purchaseForm.fields['ticket_' + str(ticket['id'])];" but insted of field HTML I get "<django.forms.fields.IntegerField object at 0x017938D0>"

oops, yeah, I meant to say getattr(form, 'attr')

Yeah, don't do form.fields['field']-- that will literally get you the field object, not the BoundField object that prints as a widget

There we go, try: ticket.form_field = form['ticket_count_' + str(ticket.id)], that will get you the BoundField you need
