I'm trying to replace the standard AdminSplitDateTime widget in my admin
site for better functionality (basically I want to display only 'available'
dates in my calender which I couldn't find how to do with the default
picker). I decided to use the bootstrap3_datetime widget.
After overriding my field to use the new widget, it doesn't seem to be
transferred into the 'clean' method (isn't in self.cleaned_data) for
validation.
*models.py*
publish_time = models.DateTimeField('Date to publish')
*admin.py*
class MyForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(MyForm, self).__init__(*args, **kwargs)
bad_dates = []
#populating bad_dates with application logic
def clean(self):
# This will always return None when using the new widget.
# When working with the default widget, I have the correct value.
publish_time = self.cleaned_data.get('publish_time', None)
publish_time = forms.DateTimeField(widget=DateTimePicker(options=
{"format": "DD-MM-YYYY HH:mm",
"startDate": timezone.now().strftime('%Y-%m-%d'),
"disabledDates": bad_dates,
})
class MyModelAdmin(admin.ModelAdmin):
form = MyForm
admin.site.register(MyModel, MyModelAdmin)
HTML-wise, the widget works well and the text field is populated with the
correct date (and with the 'bad_dates' disabled). The problem is that it
seems it isn't saved on the form.
I also tried initializing the widget in the init method by doing:
self.fields['publish_time'].widget = DateTimePicker(options=...)
But the result was the same.
I've analysed the POST request that is sent using each of the widgets. In
the default admin widget, I see that it generates two fields:
"publish_time_0" (for date) and "publish_time_1" (for time). In the
bootstrap3 widget, only a single "publish_time" field is sent.
I'm assuming that the admin site understands that the field is a
DateTimeField (from models), looks for id_0 and id_1 and that's why it
fails. Does that make sense? Is there anyway around it?
Thanks a lot!
