Snippet List

RecaptchaForm

There already is a [snippet on here](http://www.djangosnippets.org/snippets/433/) that shows how to use reCAPTCHA with Django, but being the lazya-- that I am, I wanted the form to: * display the captcha when as_table is used * handle captcha validation for me So RecaptchaForm does the trick. Just subclass from it and voila, your form will include reCAPTCHA validation. Other than that, you need to * be on Django trunk version (or use clean_data instead of cleaned_data for 0.96) * set RECAPTCHA_PRIVATE_KEY and RECAPTCHA_PUBLIC_KEY in your settings.py * make sure that the [captcha module](http://pypi.python.org/pypi/recaptcha-client) is available somewhere (i.e. that "import captcha" works)

CheckedField

Here's a snippet to pair an arbitrary form Field type (the "target field") with a checkbox. If the checkbox is not selected, the cleaned_data value for the field will be None. If the checkbox is selected, it will return the target field's cleaned value.

CSRF this!

A form with built-in CSRF protection. Include CsrfCookieMiddleware in your MIDDLEWARE_SETTINGS, subclass SafeForm and off you go. See: [this django-developers post](http://groups.google.com/group/django-developers/browse_thread/thread/2c33621003992d07?hl=en) for more info. [edit] This form is actually WAY overengineered currently. Will update soon.

Chunks template filter

A simple filter which divides an iterable (list, tupe, string, etc) in chunks, which can then be iterated over separately. A sample of the filter usage is given: a gallery template in which I needed to display images in a table, three images per row, one row for images followed by one row for their descriptions.
