JSONField
This is a custom field that lets you easily store JSON data in one of your model fields. This is updated to work with Django 1.1. **Example: (models.py)** from django.db import models import JSONField class MyModel(models.Model): info = JSONField() ** Example: (shell)** >>> obj = MyModel.objects.all()[0] >>> type(obj.info) <type 'NoneType'> >>> obj.info = {"test": [1, 2, 3]} >>> obj.save() **[Code at GitHub](http://github.com/bradjasper/django-jsonfield/tree/master)**

Truncate HTML without breaking tags
Put it in appname/templatetags/truncatehtml.py and load it with {% load truncatehtml %}, then for instance {{ some_story|truncatehtml:100 }} to truncate the story to 100 characters. Tags are not counted in the length given, and character entities count as one character. The filter should never break an open-tag text close-tag sequence without adding in the close tag. It will also preserve character entities. It won't sanitize the HTML, though: garbage in, garbage out. There's a bit more info about how it works in a [blog post](http://ole-laursen.blogspot.com/2009/05/safe-truncation-of-html.html) I wrote.

Email obfuscation filter using ROT13
An email address obfuscation template filter based on the ROT13 Encryption function in Textmate's HTML bundle. The filter should be applied to a string representing an email address. You can optionally pass the filter an argument that will be used as the email link text (otherwise it will simply use the email address itself). Example usage: {{ email_address|obfuscate:"Contact me!" }} or {{ email_address|obfuscate }} Of course, you can also use this on hardcoded email addresses, like this: {{ "[email protected]"|obfuscate }}

Simple Admin-button linking to Databrowse
If you want all the objects in your models' admin interface to have a direct link to their databrowse page (just like the *history* link).. follow these steps: 1) copy the *change_form.html* admin template in mytemplates/admin/ 2) edit *change_form.html* by adding this code right next to (before or after) the following line (=the history button markup): `<li><a href="history/" class="historylink">History</a></li>` 3) Make sure that all of you models are registered with [databrowse](http://docs.djangoproject.com/en/dev/ref/contrib/databrowse/) That's it. Obviously if you don't want ALL the models to have this link, you should use a different recipe, for example this one: [http://www.djangosnippets.org/snippets/1016/](http://docs.djangoproject.com/en/dev/ref/contrib/databrowse/)

Language aware cache decorator
Caches a view based on the users language code, a cache_key and optional function arguments. The cache_key can be a string, a callable or None. If it's None, the the name of the decorated function is used. You can pass a tuple `func_args` of arguments. If passed, these arguments are part of the cache key. See examples for details.

convenience parent class for UserProfile model
This is just a reusable convenience parent class to allow you to create and administer an automatic user profile class using the following code: class UserProfile(UserProfileModel): likes_kittens = models.BooleanField(default=True) Whenever a `User` object is created, a corresponding `UserProfile` will also be created. That's it. NB: You will still need to set `AUTH_PROFILE_MODULE` in your settings :-) (PS: It would also be nice to have the resulting class proxy the `User` object's attributes like django's model inheritance does, while still automatically creating a `UserProfile` object when a `User` object is created :-)

Quantize decimal template filter
Takes a float number (23.456) and uses the decimal.quantize to round it to a fixed exponent. This allows you to specify the exponent precision, along with the rounding method. And is perfect for monetary formatting taking into account precision.

Decorator to modify reverse() to render SSL urls
This snippet monkey-patches Django's reverse() method (use for generating URLs from vew functions and parameters) to allow certain areas of your site to automatically have URLs with the correct SSL domain in place. This saves you from having to use unnecessary redirects to guide users to an SSL-encrypted version of a page. This should still be used alongside a redirect-based method (such as [this snippet](http://www.djangosnippets.org/snippets/85/)) to ensure that the user can't access an unencrypted version of the page Simply add the code to the files mentioned in the code. This obviously won't work anywhere that doesn't use reverse(), the admin app seems to be an example of this.

ImageMagick commands from Django Templates
A template filter which wraps imagemagick's `convert` command. The filter acts upon a source image path, and returns the filtered image path. usage: {{ source_path|convert:"-resize 64x64\!" }} The filter parameter is the processing arguments for an ImageMagick 'convert' command. See e.g. http://www.imagemagick.org/Usage/resize/ Every image created is saved in a cache folder. This code does not handle removing obsolete cached images. If the filtered image path exists already, no image processing is carried out, and the path is returned.
