Documentation mentions {{ form.id }} for formsets

[Marek Onuszko]

Documentation from 1.4 up to dev mentions a mysterious variable {{ form.id }} for formsets. However, no such thing seems to exist, and it prints an empty string instead. The closest equivalent seems to be {{ form.prefix }}.

​https://docs.djangoproject.com/en/1.5/topics/forms/formsets/#manually-rendered-can-delete-and-can-order

I stumbled upon this while working on a contact form, and apparently it does seem to print something if the formset is based on a ModelForm. But in such case it's still unclear what {{ form.id }} is supposed to mean. What id is that ?

Hi,

I don't get what {{ form.id }} is supposed to be either. It was mentionned in the original ticket (#16126) and I'm guessing it was specific to that use-case (the form probably had a field called id).

I think we can safely remove that line.

However, reading that code example I noticed that it's missing the {{ form.published_date }} field so it'd be nice to add it while we're changing that code.

Thanks!

Hello,
{{form.id}} is actually necessary for inline formsets (and probably also model formsets, but I haven't tested it)

form.id is not displayed, but omitting it gives a MultiValueDict error and prevents saving when you try to save a formset having more than 1 form (which is the whole point of formsets)

This example isn't for model formsets or inline formsets. #9704 is an open ticket about mentioning form.id.
