Skip only specified spaces
Similar to `{% spaceless %}`, but only removes spaces followed by a special marker (`&nosp;`). Helps keeping proper indentation: {% skipspaces %} Lots of coffee {% if from_brazil %} from Brazil {% else %} from Columbia {% endif %} {% if tea %}&nosp;, some tea{% endif %} and a cake. {% endskipspaces %} Otherwise you'd have to write it in one looong line or get used to living with spaces before commas :) NB the marker itself is stripped from rendered html as well.

Signal to resize uploaded Fiber images as new thumbnailed images
You only have to put the code in some of your models.py and to have django-fiber installed in your system. Every image uploaded using Fiber admin dialog will be automatically resized and thumbnailed. Or whatever you need to do with it.

Coalesce for F()
Updating fields that allow for NULLs must take care about those NULLs. Use case: `Message.objects.filter(id=1).update(price=CF('price', 0) + 7)` `Message.objects.filter(id=1).update(status=CF('status') // 's')` Works for postgres. Supposedly works for mysql. Didn't test with other backends.

Async PIL resize of images
Call resize_image to replace the image with a resized and normalized version of itself. I recommend doing this with celery, but you could also hook it up to the admin interface if you're not impatient.

autotranslate po files using microsoft translator
This snippet is inspired by [dnordberg](http://djangosnippets.org/snippets/1048/) 's translation script which used google's translation script. But after google translation is no more free. I put together it to use microsoft translator's python wrapper by [openlab](https://github.com/openlabs/Microsoft-Translator-Python-API) usage ----- 1. get a bing appID from [here](https://ssl.bing.com/webmaster/developers/appids.aspx) and replace it on the top of script 2. sudo apt-get install translate-toolkit 3. sudo pip install microsofttranslator 4. sudo autotranslate.py [pofile] [sourcelangcode] [targetlangcode] Enjoy!!! **Prabhat Kumar Gupta** Python/Django Dev [http://www.prabhatgupta.com](http://www.prabhatgupta.com)

SASS/SCSS include template tag.
You'll need to `pip install pyScss` first. Converts on the fly, so you won't want to use this for much more than just testing. Usage in a template: {% load sass %} {% include_sass "disclosures/css/base.scss" %} {% include_sass "disclosures/css/grid.scss" %}

Create permissions for proxy models
Until [#11154] is fixed, django won't create permissions for proxy models for you as it does with other models, even the one you define using the [`permissions` option](https://docs.djangoproject.com/en/dev/ref/models/options/#django.db.models.Options.permissions) on your models. This snippet will make sure all permissions are create for proxy models. Just make sure this code gets loaded after the `update_contenttypes` handler is registered for the `post_syncdb` signal. Putting this code in one of your `INSTALLED_APPS' after `django.contrib.contenttypes' should do it.

True Unique Boolean Decorator
Useful when you want to keep only one instance of a model to be the default one. This is a decorative way of doing the same as in http://djangosnippets.org/snippets/1830/ Can this be made better as a class decorator (not having to declare explicitly the save method) ?

Filter change list by a date range
The Django admin site has a feature to filter objects in change list by parameters supplied in the query string. Particularly, parameters such as date\__gte and date\__lte can be used. This example is for filtering objects in change list by a date range (the date field is called expiration_date, but you can, of course, use any other name). As the server side (Django) already supports such filtering, all you need to do is to edit this for your needs (you can also add some DRY if you want) and put it into templates/admin/app_name/model_name/change_list.html. Some CSS for better layout: div.date_filter select#from_month, div.date_filter select#to_month { margin-left: 0; } div.date_filter label { margin-right: 5px; }
