Paypal form with better sandbox support
This is a class I use instead of the default PayPalPaymentsForm in django-paypal. I wanted to use the Paypal sandbox on my development site and the real Paypal site on my production site. Currently, if you want to output the Paypal form with the sandbox you have to call the sandbox() method on the form, rather than the render() method. Using this class instead of the default PayPalPaymentsForm, you can just set PAYPAL_DEBUG to True in the settings file and the form will take you through to the sandbox instead. Don't forget to set the sandbox merchant account's business email address as PAYPAL_RECEIVER_EMAIL too.

A more complete Drupal 7 compatible password hasher
Use this class to authenticate against Drupal 7 password strings. When importing passwords from Drupal, the database values should be prefixed with "drupal$". In contrast to the two present solutions, this class also works with passwords which were imported to Drupal 7 (e.g. from Drupal 6 or phpBB) and with passwords with variable iteration numbers. It is possible to use this class for encoding passwords, but due to questionable design decisions in Drupal (like truncating the non-standard base64 encoded hash at 43 characters) I'd recommend to do this this only if you really need to be able to migrate back to Drupal.

Haystack whoosh backend for stemming non-english language words
It's haystack whoosh backend code which involves stemming for specific language in time of indexing. 2 lines was changed comparing to original whoosh backend (StemmingAnalyzer replaced with LanguageAnalyzer for russian language, list of supported languages: [here](https://bitbucket.org/mchaput/whoosh/raw/default/src/whoosh/lang/snowball/__init__.py) )

A basic view for working with jQuery dataTables plugin
jQuery dataTables is a fantastic and powerful client-side plugin, which has many capabilities. There are many libraries out there that easily integrate it with django with little to no effort. However, they provide everything out of the box, which isn't always the most flexible solution. I also think beginners have a lot to learn from not using already created tools. So, finding the general examples out there lacking, I though I'd hatch out a quick example of how to very basically integrate the two. I supply two lists at the top which define how to order the fields and which are searchable (quite similar to the one defined in the admin site) and later everything is figured from there. Of course, for a little more complex implementation (say using a method instead of a field) this will not work (since getattr doesn't automatically call a function if it is a function), but this snippet isn't supposed to provide everything but a very basic usage example, which can be very quickly expended in any way needed. Anyway, this snippet should work on all django versions and all dataTables versions without a hitch. last note- I use `cStringIO` with `json.dump` out of good personal experience with that settings, though it might not be the best way to serialize the data. Good luck, share use and enjoy, ~yuvi

Dict Concat
Wanted a simple function to concatenate n dictionaries. Each dictionary passed in is deep copied to avoid any possible mutation of dictionaries being concatenated. Dictionary m's key/values will be overwritten by dictionary m+1's key/values.

Greek uppercase tag for django
Tag to correctly uppercase Greek characters with accent, copy the code in your templatetags folder in a file of your choice, load it in your templates {% load yourfile %} and use it as {% string|gruppercase %} the code works also with other languages, it won't modify anything (eg {% ukwork|gruppercase %} as it transforms only Greek characters (unless your language contains Greek characters).

Inherit the standard url tag to include domain name
This module extends the standard `url' template tag in Django and adds support for fully qualified domain name URLs. It also can be extended with simple URL load balancing techniques if desired. See my blog for the background story: <http://atodorov.org/blog/2013/12/22/django-template-tag-inheritance-howto/>

Lazy context processor.
Sometimes you have context variables that are needed on many pages in a site, but not all. You only want them to be evaluated when actually needed, especially if they are expensive calculations that do DB queries etc. The pattern to use is shown: put a callable into the context, not the final value, and also wrap the callable with memoize_nullary.

Decorator to execute a method only once
Beware if using Amazon Simple Queue Service to execute Celery tasks which send email messages! Sometimes SQS messages are duplicated which results in multiple copies of the messages being sent. This is a simple decorator which uses a cache backend to prevent the task from executing twice in a specified period. For example: @task @execute_once_in(3600*24*7) def cron_first_week_follow_up(): """ Send a follow-up email to new users! """ pass For more info see <http://atodorov.org/blog/2013/12/06/duplicate-amazon-sqs-messages-cause-multiple-emails/> <http://atodorov.org/blog/2013/12/11/idempotent-django-email-sender-with-amazon-sqs-and-memcache/>

Load Template from App
Updated a similar snippet by "King" to work with Django 1.6. This is especially useful for overriding the admin templates without having to symlink or copy them into your project. For example {% extends "admin:base.html" %} would extend the admin page base.html.
