Consider reopening ticket #11385

[Andres Osinski]

Hi everyone, I wanted to bring up a request: Ticket #11385 dealt with Django's DateTimeField being unable to handle ISO 8601 date formats.

At the time it seemed reasonable to not support this feature given, however, given the proliferation of web service APIs that return dates using this format, it is natural to use forms to validate the outputs of such services, and having it not baked in while depending on strftime's formatting behavior (which seems to fail tremendously for such datetime formats) makes working with such data very awkward.

I can volunteer to do the bulk of the effort if there's any chance to have a more experienced member of the community go over my work to make sure a decent patch can be submitted.

Cheers

Django’s DateTimeField parsing code is really targeted at values typed by humans. It doesn’t handle time zones because humans don’t tend to write them down :)

Wouldn’t it be easier to write an ISODateTimeField? It could take advantage of django.utils.dateparse.parse_datetime, which parses an ISO datetime reasonably fast and handles time zone offsets.

I'm a little unsure whether that argument continues to hold about users writing times and dates. I don't know of that many sites which don't use a datepicker of some description at least for dates, and even the admin has some client side help for picking times.

It seems reasonable that one field should be able to support both versions - this would also mean that an auto generated ModelForm is appropriate for use in API code, or in progressive enhancement situations where you wish to support AJAX from some arbitrary JS and human input (hey, and curl) all at the same endpoint.

I have personally had to write date parsing into my API code or AJAX endpoint code on multiple occasions to work around this. So, unless there is a good technical reason why this is hard to do, I would like it to be supported.
