Type less with newforms admin
I recently converted a site with over 60 models to newforms admin. I like the seperation of the display from the defintion, but it does introduce quite a bit more typing which isn't in the spirit of Django DRY... I particular I got bored of typing admin.site.register(Model, ModelAdmin) Over and over again so I wrote this little bit of code which does a bit of introspection. It assumes that 1. You import all your models into your admin.py, ie from "myapp.models import *" 2. The admin class for Model is called ModelAdmin Put this snippet at the end of your admin.py I hope that saves someone a bit of typing!

Using Google Apps Premium infrastructure for user management
To create a lower entry barrier to logging into our intranet I created a very simple backend using Google Apps Premium provisioning API (http://code.google.com/apis/apps/gdata_provisioning_api_v2.0_reference.html). This enables controlling access for your users based on their status in your Google Apps instance. *(NOTE! Since the provisioning API is only available in the Premium version of Google Apps you first need to upgrade if you haven't done so already)* Requirements: You need Google Data libraries for python. They can be downloaded from http://code.google.com/p/gdata-python-client/downloads/list Google Apps Premium -- User used by the script must have admin rights

Creator/updater fields for admin
This ModelAdmin class sets fields for models saved in admin corresponding to the user that created the object and the user that last updated the object. Trivial for the current model, but a little more involved to make it work with inlines. The fields still show up as drop-downs (`select`) in the admin, but I fixed that with a little jQuery: $(function(){ $("select[id*='creator'], select[id*='updater']").each(function(){ var user = $('option:selected', this).text(); $(this).siblings('.add-another').hide(); $(this).hide(); $(this).after(user); }); }); This could easily be subverted, but with trusted users, it makes for a quick and dirty read-only field.

Ordering a queryset by _CHOICES
I recently needed to sort a list of objects by cardinal direction clock-wise. Since this is different than alphabetical, and I didn't want to use a dictionary to map to integers, here is what I came up with. There may be a cleaner way to do this by overriding some object methods, but I just thought I'd put this out there anyway.

Admin definition converter (for newforms-admin)
A script I wrote a little while ago to help speed up newforms-admin conversion. From memory it works best when run from an old-forms installation, but it is still useful post-conversion. There are some features missing, but it's supposed to be a starter. Just install this command and run: ./manange.py port2nfa > admin.py (To install, copy the file to management/commands/port2nfa.py in an app somewhere)

Add a "remove file" field for Image- or FileFields
This adds a checkbox in the admin site that removes the reference to a file uploaded via a FileField (or ImageField). It does not delete the actual file.

Template tag: split list to n sublists
Based on [this snippet](http://www.djangosnippets.org/snippets/660/), adapted to split a list into *n* number of sublists, e.g. split a list of results into three evenly-divided sublists to enable display of the results in three columns on one page with CSS. Tag: `{% list_to_columns your_list as new_list number_of_columns %}` The split_seq solution comes from a comment by Sebastian Hempel on [this post](http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/425397). More info [here](http://herself.movielady.net/2008/07/16/split-list-to-columns-django-template-tag/).

ModelForm-based create_update generic views
This is a ModelForms-based rewrite of the create_object and update_object generic views, with a few added features. The views now accept a "form_class" argument optionally in place of the "model" argument, so you can create and tweak your own ModelForm to pass in. They also accept a "pre_save" callback that can make any additional changes to the created or updated instance (based on request.user, for instance) before it is saved to the DB. Usage: just save the code in a file anywhere on the PythonPath and use the create_object and update_object functions as views in your urls.py.

Dynamic Django settings context processor
Here's a nice way of easily passing only certain settings variables to the template. Because of the way Django looks up context processors, we need a little hack with sys.modules. The [blog entry is here](http://sciyoshi.com/blog/2008/jul/10/dynamic-django-settings-context-processor/).
