Support IP ranges in INTERNAL_IPS

CIDR ( http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing ) is a well-known IP range syntax. This CIDR_LIST class can be used to make ranges of IPs considered "internal" for Django's debugging and security purposes. (Django only ever needs to do "ip in INTERNAL_IPS" so __contains__ is sufficient for the purpose.) For example, to make localhost and the entire block of 10.0.0.* considered to be internal, use: INTERNAL_IPS = CIDR_LIST([ '127.0.0.1', '10.0.0.0/24' ])

Decorate Template Tag (In-Line include and extend with local context)

I had an issue with the django templating system, where by if I included several different files at the same level on one template.. and all the included templates extended the same base template. It would render the defined blocks for the first inclusion for all. i.e. everything in the parent that is being extended would be not updated for the subsequent inclusion. So, if anyone else has this problem. I have a solution that I sorta wanted for other reasons anyway. It's called a decorator tag, you can include and extend a template at the same time - in-line, with local context scoping so it only affects that tag. This is also a nice way to avoid creating .html files for simple extending purposes.

Drop in dynamic formsets in admin

A very plugable way to get Stanislaus jquery dynamic formset working in the admin with adding just one template. Add the following to templates/admin/APP/MODEL/change_form.html and also update the MODEL in the prefix setting. Thanks Stanislaus [http://elo80ka.wordpress.com/2009/10/10/jquery-plugin-django-dynamic-formset/](http://elo80ka.wordpress.com/2009/10/10/jquery-plugin-django-dynamic-formset/) [http://go2.wordpress.com/?id=725X1342&site=elo80ka.wordpress.com&url=http%3A%2F%2Fcode.google.com%2Fp%2Fdjango-dynamic-formset%2F](http://go2.wordpress.com/?id=725X1342&site=elo80ka.wordpress.com&url=http%3A%2F%2Fcode.google.com%2Fp%2Fdjango-dynamic-formset%2F) [http://www.djangosnippets.org/snippets/1389/](http://www.djangosnippets.org/snippets/1389/)

jstree integration to django admin

You have some tree-like structure in your models, for example: `class MyModel(models.Model): parent = models.ForeignKey('self', verbose_name=u'Parent', \ null=True, blank=True, related_name='children') name = models.CharField(u'Раздел', max_lengtch=255) position = PositiveSmallIntegerField(u'Позиция', default=0) class Meta: ordering = ('position',)` To see it as a tree in admin's object list(you also can sort items, move to another parents by drag-n-drop; and rename them) add this to admin.py: `class MyModelAdmin(admin.ModelAdmin): ordering = ('position',) list_display = ('pk','name','parent','position') raw_id_fields =('parent',) list_per_page = 900 #we sould have all objects on one page list_editable = ('name','position','parent') def parent_id(self,obj): return obj.parent and obj.parent.id or '0' class Meta: model = MyModel class Media: js = [settings.MEDIA_URL + s for s in ('lib/jquery-1.3.2.min.js', 'lib/jquery.tree.min.js', 'lib/plugins/jquery.tree.contextmenu.js', 'lib/mymodel_admin.js',)] css = { 'all':(settings.MEDIA_URL+'css/nestedsortablewidget.css',) }` mymodel_admin.js is the code listed here, if you have different title field(not "name"), change var title_column in javascript, list_display and list_editable. jstree can be obtained here: [jstree](http://www.jstree.com/) screenshot is in [my blog](http://tabed.org/blog/2010/01/06/jstree-in-django-admin/)

"Save and Continue" keyboard command for admin, with autoscroll

This snippet is helpful if you do a lot of editing on a single large admin form (for example, in a rich text field), and want to frequently save your progress. If you press control-S, or command-S on a Mac, the admin change form will save and reload, and the page will scroll back down to where you last were. This snippet relies on jquery, [jquery.cookie](http://plugins.jquery.com/project/cookie), and the [shortcut.js](http://www.openjs.com/scripts/events/keyboard_shortcuts/) keyboard library (which doesn't use jquery, but seemed more robust than the jquery keyboard plugins I saw). It uses a temporary cookie to remember where the page was scrolled to, to avoid having to override the admin behavior. Note: don't put this in templates/admin/change_form.html -- the circular import causes a Django crash. *Edit: Had forgotten to include jquery.cookie, which I was already including elsewhere.*

Choices

This allows you to access the choices (and their respective values) you create as a dictionary. It works great within django and it allows you to reference the choices as a dictionary (CHOICES[CHOICE1]) instead of CHOICES[0][0]... it is a tuple... but I mean, come on... what if you change the order? If you need the tuple just call CHOICES.choices and it will return the standard tuple.
