Hi all, I have created a custom widget using the branch newforms-admin to represent (see code below):
To test it, create a couple of countries, then a few cities attached to those countries, and then create a new Person. In the class PersonOptions, the line "formfield.widget.render = widgets.RelatedFieldWidgetWrapper(formfield.widget.render, db_field.rel, self.admin_site)" allows me to get the green cross. By clicking that cross, a popup appears and you can add a new city. Until then it's great.... ....except that once the new city is saved, the popup doesn't close. It remains blank, and if you look at the html source of that popup you'll get something like: "<script type="text/javascript">opener.dismissAddAnotherPopup(window, 7, "New York");</script>" By looking at the function "dismissAddAnotherPopup" in the file "http://127.0.0.1:8000/media/js/admin/RelatedObjectLookups.js"; it seems that if the widget is not a "select" component, then it won't be refreshed. So, my questions: - How can we get that pop up window to close when the new city is saved? - How can we refresh the custom widget? - How can we put the green cross in a better place? (with the current template it is placed in the bottom left corner, which is not that visible) Thanks a lot for your help!
