TemplateView and FormView inconsistency

[step21]

Hi all,

When developing I noticed an inconsistency - when using TemplateView, kwargs are passed to context, but not when using FormView or others.

Source comparison:

Relevant super old issue talking about depreciation here:
https://code.djangoproject.com/ticket/19878

I discussed this briefly on IRC and was told to post here, as it is an inconsistency and maybe should be fixed but maybe wasn’t for a reason. Seeing as there was already talk of depreciating it several years ago and no clear opposition, maybe I could prepare a patch for it?
Any thoughts?

Hi,

After reading the ticket, I agree this could be deprecated as a backwards incompatibility. The deprecation plan suggested by loic84 looks like it could work but would be a bit unwieldy on large projects. Maybe there's another path?

One thing that's not explicitly in the discussion: the view kwargs are always accessible inside templates because ContextMixin.get_context_data passes 'view', and view.kwargs is always set by View.setup().

Thanks,

Adam

I do not have a better idea right now, but also do not know the django core code that well. Personally, as you could get all TemplateViews via Ack or another code search method, I do not think replacing them would take long.

I came up with a PR that will raise a deprecation warning on variable access - see the ticket.
