Hi,
Below is a Javascript file with the hackery we use to trigger a change
event when the add/change popup window is dismissed, which works for Django
1.7 at least.
Hopefully it will help, or at least point you in the right direction.
Regards,
James
/*
* Trigger change events when Django admin's popup window is dismissed
*/
(function($) {
$(document).ready(function() {
// HACK to override `dismissRelatedLookupPopup()` and
// `dismissAddAnotherPopup()` in Django's RelatedObjectLookups.js to
// trigger change event when an ID is selected or added via popup.
function triggerChangeOnField(win, chosenId) {
var name = windowname_to_id(win.name);
var elem = document.getElementById(name);
$(elem).change();
}
window.ORIGINAL_dismissRelatedLookupPopup =
window.dismissRelatedLookupPopup
window.dismissRelatedLookupPopup = function(win, chosenId) {
ORIGINAL_dismissRelatedLookupPopup(win, chosenId);
triggerChangeOnField(win, chosenId);
}
window.ORIGINAL_dismissAddAnotherPopup =
window.dismissAddAnotherPopup
window.dismissAddAnotherPopup = function(win, chosenId) {
ORIGINAL_dismissAddAnotherPopup(win, chosenId);
triggerChangeOnField(win, chosenId);
}
});
})(jQuery);
