The FilteredManyToMany widget needs javascript in 'stacked.html' and 'tabular.html' when using inline content

[replytosander@…]

I'm developing a custom sortable manytomany widget which allows the user to order the items in the widget.

You can find it here: ​https://github.com/fabrique/django-sortedm2m

When using inline models the widget needs the javascript in stacked.html and/or tabular.html. It initializes a new instance when adding an inline item.

To keep the sortedm2m library as pluggable as possible I would like to know how I can provide this javascript in the library. This way a developer doesn't need to override the admin templates.

This doesn't seem possible at the moment. Maybe there should be a way to provide document ready javascript in the scope of the widget.

Any ideas on this?

Code used in overridden stacked.html template:

var updateOrderedSelectFilter = function() {
            // If any SelectFilter widgets are a part of the new form,
            // instantiate a new SelectFilter instance for it.
            if (typeof OrderdSelectFilter != "undefined"){
                $(".selectfilter").each(function(index, value){
                    var namearr = value.name.split('-');
                    OrderdSelectFilter.init(value.id, namearr[namearr.length-1], false, "{% admin_media_prefix %}");
                });
                $(".selectfilterstacked").each(function(index, value){
                    var namearr = value.name.split('-');
                    OrderdSelectFilter.init(value.id, namearr[namearr.length-1], true, "{% admin_media_prefix %}");
                });
            }
        }

This is a feature request, and it isn't very precise. In such cases, it's best to write to the ​django-developers mailing list, and open a ticket once a concrete action plan has been determined.

Overriding admin templates is the canonical way to inject additional features in the admin pages. Your library can ship templates replacing the admin's built-in templates; they will be used if you app comes before django.contrib.admin in INSTALLED_APPS.
