python - Django bootstrap3_datetime widget in admin site doesn't pass form data -

i'm trying replace standard adminsplitdatetime widget in admin site better functionality (basically want display 'available' dates in calender couldn't find how default picker). decided use bootstrap3_datetime widget.

after overriding field use new widget, doesn't seem transferred 'clean' method (isn't in self.cleaned_data) validation.

models.py

publish_time = models.datetimefield('date publish') 

admin.py

class myform(forms.modelform):      def __init__(self, *args, **kwargs):         super(myform, self).__init__(*args, **kwargs)         bad_dates = []         #populating bad_dates application logic      def clean(self):          # return none when using new widget.         # when working default widget, have 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, widget works , text field populated correct date (and 'bad_dates' disabled). problem seems isn't saved on form.

i tried initializing widget in init method doing:

self.fields['publish_time'].widget = datetimepicker(options=...) 

but result same.

what missing here? possible modify widgets in admin site?

thanks!

update: i've analysed post request sent using each of widgets. in default admin widget, see generates 2 fields: "publish_time_0" (for date) , "publish_time_1" (for time). in bootstrap3 widget, single "publish_time" field sent.

i'm assuming admin site understands field datetimefield (from models), looks id_0 , id_1 , that's why fails. make sense? there anyway around it?
