SelectDateWidget don't render correctly

[Martin Conte Mac Donell <Reflejo@…>]

I don't see why you are forcing unicode to datetime values.

[terryh]

The "value" from instance, then the "value" is datetime.date instance.
The "value" from request.POST, then the "value" is unicode string.

force_unicode just make sure the "value". make it render correctly, no matter where it come from.

[Martin Conte Mac Donell <Reflejo@…>]

Actually if you are using SelectDateWidget it's suppose to have only numbers (represented as string; but just numbers) from request.POST. I mean, value_from_datadict is returning '%s-%s-%s' % (y, m, d). And those y m and d MUST be numbers to create datetime.date().

I'm still not seeing where is the unicode chance here.

[terryh]

the following alwayse asume "value" is string

33 def render(self, name, value, attrs=None):
34 try:
35 value = datetime.date(*map(int, value.split('-')))

But if there is no y, and m and d, will return datetime.date, if you try form_for_instance, then render it, you will see, just in my case, maybe I'm wrong

57 def value_from_datadict(self, data, files, name):
58 y, m, d = data.get(self.year_field % name), data.get(self.month_field % name), data.get(self.day_field % name)
59 if y and m and d:
60 return '%s-%s-%s' % (y, m, d)
61 return data.get(name, None)

Just to be clean here.

What "don't render correctly" means?. What did you see?

without this patch, this widget select nothing

[Martin Conte Mac Donell <Reflejo@…>]

This is IMHO a better way to do that

[Martin Conte Mac Donell <Reflejo@…>]

You don't need to force unicode here, you should ask if the comming value is a String (unicode or str) or datetime.

(Duplicate of #5917?)

This is IMHO a better way to do that (Err.. Sorry for the other one)
