DRY custom ModelAdmin.list_display methods with a decorator

If you add a lot of custom `ModelAdmin` methods to `list_display` like I do, you know it can require a lot of repetition. Notice how adding 'checkbox' to `list_display` requires typing the method name 4 times: class ExampleAdmin(admin.ModelAdmin): list_display = ['checkbox', '__str__'] def checkbox(self, object): return '<input type="checkbox" value="%s"/>' % object.pk checkbox.short_description = mark_safe('&#x2713;') checkbox.allow_tags = True Using this decorator, the name only needs to be typed once: class ExampleAdmin(admin.ModelAdmin): list_display = ['__str__'] @add(list_display, mark_safe('&#x2713;'), 0, allow_tags=True) def checkbox(self, object): return '<input type="checkbox" value="%s"/>' % object.pk

whitespaceoptimize block tag

This is a custom block tag and is used like this: {% load whitespaceoptimize %} {% whitespaceoptimize "css" %} /* CSS comment */ body { color: #CCCCCC; } {% endwhitespaceoptimize %} And when rendered you get this output: body{color:#CCC} To install it, download the snippet and call it `myapp/templatetags/whitespaceoptimize.py`. (Make sure you have a `__init__.py` in the `templatetags` directory) You need to download and install [slimmer](http://www.issuetrackerproduct.com/Download#slimmer) and put on your Python path. The block tag can be used for `javascript` and `html` as well as `css`. You can also let it guess the format; this would work for example: {% whitespaceoptimize %} <table> <tr> ... {% endwhitespaceoptimize %} ...but this would just replicate the functonality of the [built-in spaceless tag](http://docs.djangoproject.com/en/dev/ref/templates/builtins/#spaceless)

Orderable inlines using drag and drop with jQuery UI

An easy way of making inlines orderable using drag-and-drop, using [jQuery UI's](http://ui.jquery.com/) sortable() plugin. First, add an "order" field to the inline models which is an IntegerField, and set that model to use 'order' as its default order_by. Then hook in the JavaScript. This should make them drag-and-drop sortable using jQuery UI, and also hide the divs containing those order fields once the page has loaded. This technique is unobtrusive: if JavaScript is disabled, the order fields will be visible and the user will be able to manually set the order by entering numbers themselves.

WorldIP - access to IP database over API

The WorldIP database provides real-world geographical location. Database is more correct than [Whois records and Whois-based databases](http://www.wipmania.com/en/blog/why-worldip-data-rather-than-whois-data-examples/), that show geographic locations of network owners, and not the geographic location of Internet-connected PC or appliance itself.

Bind Administration

Binds $Model to $ModelAdmin without having to specify each binding manually. The ModelAdmins **must** have the same name as the model (as well as same case) with Admin appended. Example: from django.db import models class SomeModel(models.Model): name = models.CharField(max_length=255) class AnotherModel(models.Model): name = models.CharField(max_length=255) # bind administration bind_administration('myproject.myapp.models', 'myproject.myapp.admin')
