Django Admin: Using a custom widget for only one model field

阅读更多关于 Django Admin: Using a custom widget for only one model field

I have a DateTimeField field in my model. I wanted to display it as a checkbox widget in the Django admin site. To do this, I created a custom form widget.

How might one change the default widget for all DateFields to a custom MyDateWidget? I'm asking because I want my application to have a jQueryUI datepicker for inputting dates. I've considered a custom field that extends django.db.models.DateField with my custom widget. Is this the best way to implement this sort of across-the-board change
