Checks if the request is an AJAX request, if not it returns an HttpResponseNotFound. It looks for the XMLHttpRequest value in the HTTP_X_REQUESTED_WITH header. Major javascript frameworks (jQuery, etc.) send this header in every AJAX request.
A general AntiSpamForm using some tricks to prevent spam based on current [django.contrib.comments.forms](http://code.djangoproject.com/browser/django/trunk/django/contrib/comments/forms.py). It uses a timestamp, a security hash and a honeypot field. See [AntiSpamModelForm](http://www.djangosnippets.org/snippets/1856/) too.

Easy way to generate image thumbnails for your models. Works with any Storage Backend. From: [http://code.google.com/p/django-thumbs/](http://code.google.com/p/django-thumbs/) **Usage example:** ============== photo = ImageWithThumbsField(upload_to='images', sizes=((125,125),(300,200),) To retrieve image URL, exactly the same way as with ImageField: my_object.photo.url To retrieve thumbnails URL's just add the size to it: my_object.photo.url_125x125 my_object.photo.url_300x200 Note: The 'sizes' attribute is not required. If you don't provide it, ImageWithThumbsField will act as a normal ImageField **How it works:** ============= For each size in the 'sizes' atribute of the field it generates a thumbnail with that size and stores it following this format: available_filename.[width]x[height].extension Where 'available_filename' is the available filename returned by the storage backend for saving the original file. Following the usage example above: For storing a file called "photo.jpg" it saves: photo.jpg (original file) photo.125x125.jpg (first thumbnail) photo.300x200.jpg (second thumbnail) With the default storage backend if photo.jpg already exists it will use these filenames: photo_.jpg photo_.125x125.jpg photo_.300x200.jpg **Note:** It assumes that if filename "any_filename.jpg" is available filenames with this format "any_filename.[widht]x[height].jpg" will be available, too.
This is exacly the same snippet as #197 http://www.djangosnippets.org/snippets/197/ but returning search enigne, search engine domain and search term in: request.search_referrer_engine request.search_referrer_domain request.search_referrer_term I wanted to show ads only to people comming from search engines so I took snippet #197 and modify it to put that info in the request object.
This is the same as [{% widthratio %}](http://docs.djangoproject.com/en/dev/ref/templates/builtins/#widthratio) but when the given value is greater than the max_value it just uses the max_value. This way the result is never greater than max_value. It also returns max_width if the max_value is 0 instead of returning a blank string. Usage example: {% smart_widthratio this_value max_value 100 %}
