#13968 closed (fixed)

SelectDateWidget does not validate chosen date

Reported by: mitar Owned by: ramiro
Component: Forms Version: 1.2
Severity: Keywords:
Cc: mmitar@… Triage Stage: Accepted
Has patch: no Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: UI/UX:


SelectDateWidget does not validate chosen date and does not show an error to the user about invalid date (like 31 February) but silently discards it and resets/nullify the value. So user does not get any feedback and possibility to correct the date.

This is with USE_L10N set to True.

The problem is probably that any ValueError errors from datetime are silently discarded and input date is taken as it is invalid format not invalid date.

  • Needs documentation unset
  • Needs tests unset
  • Patch needs improvement unset
  • Triage Stage changed from Unreviewed to Accepted

Here is code to reproduce the bug:

In [1]: from django import forms

In [2]: from django.forms.extras.widgets import SelectDateWidget

In [3]: class DateForm(forms.Form):
   ...:     date = forms.DateField(widget=SelectDateWidget)

In [4]: form = DateForm({'date_month': '2', 'date_day': '31', 'date_year': '2010' })

In [5]: form.is_valid()
Out[5]: False

In [6]: form.errors
Out[6]: {'date': [u'This field is required.']}

At the very least, the error here should be "invalid date".

Looks like it's fixed in the latest trunk. Following the same example, I get the following -

>>> from django import forms
>>> from django.forms.extras.widgets import SelectDateWidget
>>> class DateForm(forms.Form):
...     date = forms.DateField(widget=SelectDateWidget)
>>> form = DateForm({'date_month':'2', 'date_day':'31', 'date_year':'2010'})
>>> form.is_valid()
>>> form.errors
{'date': [u'Enter a valid date.']}

  • Owner lemanal deleted
  • Status changed from assigned to new

This still shows up for me when I explicitly set USE_L10N=True in but not otherwise.

As I reported, the problem is only with USE_L10N set to True (default is False).

In [15417]:

[1.2.X] Fixed #13968 -- Fixed SelectDateWidget processing of an invalid date input value when USE_L10N is on, for consistency with its behavior when USE_L10N=False (now the form field reports the validation error in both cases). Thanks mitar for the report.

Backport of [15416] from trunk
