I've written a new plugin that provides a select widget that can be refreshed via ajax, along with a button that opens a dialog to add new items to the linked table. When the dialog is closed, the select widget is automatically refreshed via ajax and the added item(s) are available as selectable options. You can download or clone the file from the github repository: https://github.com/monotasker/plugin_ajaxselect
In one sense this is a duplication of the "select_or_add" module that has been available on web2py slices. Under the hood, though, they are quite different. My ajaxselect plugin does not manipulate the select widget on the user side (inserting options via jquery). Instead, I use web2py's built in ajax functionality to refresh the widget *from the db*. I think this will make for a more robust and versatile plugin. Please test it out and let me know about (a) bugs and (b) additional features you would like to see (more customizability, etc.). My immediate plan is to expand the plugin to use the same approach for filtering the contents of one select widget based on the value of another. The plugin is licensed under GPL3, so feel free to adapt and reuse it as you like. Cheers, Ian
