Question

I’m trying to build my own custom django form widgets (putting them in widgets.py of my project directory). What should the value ‘value_from_datadict()’ return? Is it returning a string or the actual expected value of the field?

I’m building my own version of a split date/time widget using JQuery objects, what should each part of the widget return? Should the date widget return a datetime and the time widget return a datetime? What glue code merges the two values together?

For value_from_datadict() you want to return the value you expect or None. The source in django/forms/widgets.py provides some examples.

But you should be able to build a DatePicker widget by just providing a render method:

DATE_FORMAT = '%m/%d/%y'  class DatePickerWidget(widgets.Widget):     def render(self, name, value, attrs=None):         if value is None:             vstr = ''         elif hasattr(value, 'strftime'):             vstr = datetime_safe.new_datetime(value).strftime(DATE_FORMAT)         else:             vstr = value         id = 'id_%s' % name         args = [             '<input type=\'text\' value=\'%s\' name=\'%s\' id=\'%s\' />' % \             (vstr, name, id),             '<script type=\'text/javascript\'>$(\'#%s\').datepicker({dateFormat:'mm/dd/y'});</script>' % id             ]         return mark_safe('\n'.join(args))
