A simple jQuery javascript that collapses all stacked inline rows for better handling of large inline fieldsets.

It also adds "Show"/"Hide"-buttons for showing/hiding each row, which could be customized and styled using css.

Usage (see below for example):

Include the javascript on your admin page, together with jQuery, and it'll automatically affect all stacked inlines.

Developed for:

  • jQuery 1.3.2
  • Django trunk (tested in Django v1.0.2)
  • (Might work with other versions with or without adjustments, but not tested)

Use example:

admin.py:

class DateInline(admin.StackedInline):
    model = Date
    extra = 10

class EventAdmin(admin.ModelAdmin):    
    inlines = [DateInline]

    class Media:
        js = ['js/jquery-1.3.2.min.js', 'js/collapsed_stacked_inlines.js',]

admin.site.register(Event, EventAdmin)

            fs.addClass('stacked_collapse');
        else
            fs.addClass('stacked_collapse collapsed');
        
        // Add toggle link
        h3.prepend('<a class="stacked_collapse-toggle" href="#">(' + gettext('Show') + ')</a> ');
        h3.find('a.stacked_collapse-toggle').bind("click", function(){
            fs = $(this).parent('h3').next('fieldset');
            if (!fs.hasClass('collapsed'))
            {
                fs.addClass('collapsed');
                $(this).html('(' + gettext('Show') + ')');
            }

            {
                fs.removeClass('collapsed');
                $(this).html('(' + gettext('Hide') + ')');
            }
        }).removeAttr('href').css('cursor', 'pointer');
    });
});

Now I'm using Django 1.2 beta 1 SVN-12660, and the admin interface now includes a button to dynamically add new inlines. So I exclude the empty inline that Django has hidden, with this:

$('div.inline-group div.inline-related:not(.tabular):not(.empty-form)')...

Adding ":not(.empty-form)')" to the selector excludes all dynamic inlines, and they always appear expanded (I like that way, so the user knows what just created)

xenolog (on June 6, 2010):

For use with Django 1.2 we need change:

jQuery(function($) {

to

(function($) {
    $(document).ready(function() {

and last

});

to

    });
})(django.jQuery);

In this case call jQuery-XXXXX.js from Media from admin.ModelAdmin not nessesary.
