posting date Date has wrong format. Use one of these formats instead: YYYY[-MM[-DD]] about ember-django-adapter HOT 16 OPEN

I tried new Date().toJSON().slice(0, 10), and that works. Seems a reasonable workaround.

from ember-django-adapter.

It seems that the issue is that I am only storing a date in the backend. The date is defined in my model as follows:

event_date = models.DateField(default=date.today)

If I replace this with

event_date = models.DateTimeField(default=datetime.now)

then everything works as expected. Nevertheless, I'd like it if the adapter/DRF could convert the JS Date object to the appropriate day. However, I can imagine that this is simply beyond what the adapter can reasonably do. (How could it know that the API only wants a date?)

Having thought it through, my guess is that there is no way for the adapter to solve my problem. Feel free to close. Comments are welcome.

OK, I was too quick. It turns out that in the DateTimeField case, the API does not return 400, but it does not record the date field at all. So my workaround doesn't work actually. Whether the back-end expects a DateField or a DateTimeField it doesn't quite work. In the first case the POST returns 400. In the second case it is 200, but is silently unsuccessful.

The adapter should work with both DateField and DateTimeField without too much headache. I am looking into this.

@ewilson this is still on my todo list. currently battling some dev issues with ember-cli and bower

@dustinfarris No worries, its not a blocker for my toy project. I appreciate what you are doing.

from ember-django-adapter.

I've confirmed this bug. Basically, Ember has one notion of datetime, whereas Django has date and datetime. Ember Data's DateTransform sends a full ISO-8601 datetime value for everything, and DRF blows up if the model's field is a DateField (as opposed to a DateTimeField).

Personally, I think this is a bug in DRF, or at least a deficiency. We will either need to open a PR with DRF (that may or may not get accepted), or add custom date and datetime transforms to the adapter library that can be imported as needed by EDA users.

I'm open to opinions on which way is best, but I'm thinking the custom transforms would be nice quick fix for now.

It looks like the folks over at DRF already gave this some thought: https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/fields.py#L920-L922

Hi I'm using AngularJS and AngularJS Bootstrap UI and the date returned by the JS datepicker is failing with the same error.

On Django the model field is

date_of_birth = models.DateField(null=True, blank=True)

and when I pass it via POST the date is like this

u'1987-09-03T00:00:00.000Z'

but the serializer.is_valid() return that error

from ember-django-adapter.

Hi @StErMi, I'm not sure if it's possible to override that in Angular, but as a workaround you can tell DRF to accept a different format. http://www.django-rest-framework.org/api-guide/settings/#date-and-time-formatting

from ember-django-adapter.

What I'm passing inside the POST is the ISO-8601 standard representation of a Javascript date.
It's pretty strange that DRF is not parsing it correctly.

from ember-django-adapter.

Yeah, DRF will process that just fine for DateTimeField, but not for DateField.

from ember-django-adapter.

Is it a bug? Should we report it?

No, it's a design decision. See the link I posted—DRF is explicit about the formats that are accepted, but you can change them in your settings if you need to.

@ewilson thanks. That sounds like a candidate for a "date" transform.
