Dynamically adding forms to a formset with jQuery

I recently worked on an application, where I had to provide a way for users to search for objects based on user-defined properties attached to these objects. I decided to model the search form using a formset, and I thought it'd be a good idea to allow users dynamically add and remove search criteria. The script (dynamic-formset.js) should be re-usable as-is: 1. Include it in your template (don't forget to include jquery.js first!). 2. Apply the 'dynamic-form' class to the container for each form instance (in this example, the 'tr'). 3. Handle the 'click' event for your `add` and `delete` buttons. Call the `addForm` and `deleteForm` functions respectively, passing each function a reference to the button raising the event, and the formset prefix. That's about it. In your view, you can instantiate the formset, and access your forms as usual.

Dynamic tabular inlines with optional drag-n-drop sorting

This jQuery javascript enables dynamic add/delete of rows in tabular inlines. It adds a "+" icon at the bottom of the inline to allow addition of new rows, and replaces the default delete checkbox with a "x" icon for deletion, giving you the possibility to add/delete rows instantly without reloading the page. In addition, it gives you drag-n-drop ordering functionality with a named position model field using jQuery UI Sortable. **Usage (see below for example):** Just include the javascript on your admin page, together with jQuery, and it'll automatically affect all tabular inlines. Optionally, also include jQuery UI Sortable and an Integer field in your inline model named "position" (or whatever you set "position_field" to), which will automatically hide the position field and enable drag-n-drop sorting. **Developed for:** * jQuery 1.3.2 * jQuery UI 1.7.1 * Django trunk (tested in Django v1.0.2) * (Might work with other versions with or without adjustments, but not tested) **Settings (in top of javascript):** * "position_field" is the name of an integer model field that is used for ordering the inline model. If left empty or not found, the drag-n-drop functionality is dropped. Defaults to "position". * "add_link_html" for custom look of "add"-buttons. Defaults to Django's built-in "+" image icon. * "delete_link_html" for custom look of "delete"-buttons. Defaults to Django's built-in "x" image icon. **Use example: ** *admin.py:* class NameInline(admin.TabularInline): model = Name extra = 1 class PersonAdmin(admin.ModelAdmin): inlines = [NameInline] class Media: js = ['js/jquery-1.3.2.min.js', 'js/ui/ui.core.js', 'js/ui/ui.sortable.js', 'js/dynamic_inlines_with_sort.js',] css = { 'all' : ['css/dynamic_inlines_with_sort.css'], } admin.site.register(Person, PersonAdmin) *models.py:* class Person(models.Model): year_born = models.PositiveIntegerField(_('year born'), null=True, blank=True) class Name(models.Model): profile = models.ForeignKey(Profile, verbose_name=_('profile')) position = models.PositiveIntegerField(_('position'), default=0) name = models.CharField(_('name'), max_length=100) class Meta: ordering = ('position',) *dynamic_inlines_with_sort.css:* /* To make row height of saved items same as others */ .inline-group .tabular tr.has_original td { padding-top:0.5em; } .inline-group .tabular tr.has_original td.original p { display:none; } Please post bugs in comments.

Firebug Lite Middleware

This middleware allows you to easily include the excellent debugging tool Firebug Lite in your projects. To install it, just add the middleware class to your list of installed middleware, pretty much anywhere in the list. If DEBUG is True, and your IP address is in the list of INTERNAL_IPS, Firebug Lite will load. It will, however, only load in browsers that are **not** Firefox, as I'm assuming that you have the **real** Firebug installed in Firefox. If you don't, go install it--what's wrong with you? Check out http://getfirebug.com/lite.html for more information.

Dynamically add inlines

These functions use JQuery to dynamically add new entries for stacked or tabular inlines on a change form. To enable it, change the parent model to include this Javascript as well as JQuery. Here's an example: class MeetingAdmin(admin.ModelAdmin): inlines = [MeetingDonationInline, MeetingExtraInline] class Media: js = ["/media/jquery-1.3.2.min.js", "/media/dynamic_inlines.js"]

Admin list_display Ajax

Sometimes it can be time consuming to go through a bunch of objects in Django's Admin if you only need to update one field in each. An example of this is an `order` field that allows you to manually set the order for a queryset. **This snippet contains examples of how to set up the Admin list_display to make Ajax calls to a custom view.** The following code may not be worthy of being a snippet, it's all pretty straightforward, but here it is for those who just want to copy-and-paste.

ajax error sink

Often its useful to get error information for ajax/javascript errors happening on various clients. This can go to something like this: # error_sink def error_sink(request): # post request, with event name in "event", and event data in "data" context = request.REQUEST.get("context", "") context = cgi.parse_qs(context) context["data"] = cgi.parse_qs(context.get("data", [""])[0]) context["user"] = request.vuser context["referrer"] = request.META.get('HTTP_REFERER', "referrer not set") context = pformat(context) send_mail( "ajax error", context, "[email protected]", ["[email protected]",], fail_silently=True ) return JSONResponse({"status": "ok" }) # }}}

Admin Hack: Quick lookup of GenericForeignKey id by ContentType

Generic Relations with django.contrib.contenttypes.generic.GenericForeignKey work well for models but the admin interface just shows the object id as an integer with no easy way to lookup the id of a new object. This jquery javascript adds a "Lookup <ContentType Name>" link next to the object id field in the admin interface. This is done by reusing the showRelatedObjectLookupPopup() function provided with django which is used when the field is included in raw_id_fields (a little magnifying glass linked to popup object selector shows up). This essentially works the same way but changes which model's objects are shown and selected in the popup based on the ContentType selected for object_type

jQuery ajax search

This is the result of my first tests with jQuery and Django. After entering a search term it gets search results using ajax and json. Then is uses the rather crude `result_table` function to generate a table of results. Django is on the serverside for generating json

Add special field lookups to the Admin list_filter display

Ever wanted to add an atypical [field lookup](http://www.djangoproject.com/documentation/db-api/#field-lookups) to the Django Admin list_filter filters, like `__isnull` or `__in`? This jQuery snippet allows you to do just that. Since you can access those additional filters by directly typing them into in the Admin URL, the tricky part is to add those to the regular list_filter display. A lot of this code is spent checking on querystring matches which is ugly and error-prone -- if you see any problems or room for improvement, drop me a comment! A suggestion of where to place this code is in `templates/admin/yourapp/yourmodel/change_list.html`. Mine kinda looks like this: {% extends "admin/change_list.html" %} {% block content %} <script src="/static/js/jquery-1.2.2.min.js" type="text/javascript"></script> <script type="text/javascript"> // the JavaScript posted in this snippet </script> {{ block.super }} {% endblock %}
