Filter to add zero-width space to break up long words

If you have long words (no spaces) that are so long that it's messing up your design, add a 0-width space in the word every X chars. Usage: Step 1. Inside your app's directory, create dir called 'templatetags'. In that directory, create a .py file (say 'app_extras.py'). Make sure you make this a python module, make an empty the init .py (with the 2 underscores on each side). Step 2. Inside template (make sure app is on INSTALLED_APPS list in settings.py): {% load app_extras %} Step 3. Enjoy! {{ some_long_word_with_no_breaks|zerowidthspace_separator:25 }}

Unique naming for file uploads

This snippit can be used to generate unique file names for uploads. `upload_to` allows a callable, but only provides two arguments: `instance` and `filename`. In order to prevent dumping all of the files for a model into one directory, this utilizes the `partial` decorator from `functools`, which essentially allows adding an extra argument to the function. The returned path will be of the form: `[model name]/[field_name]/[random hash].[filename extension]`

UKPhoneNumberField GB v3 (improved)

Validates and cleans UK telephone numbers. Number length is checked, and numbers are cleaned into a common format. For example, "+44 (0)1234 567890" will be stored as "01234 567890". Can reject premium numbers (0912 312 3123) or service numbers (1471, 118 118) with UKPhoneNumberField(reject=('premium', 'service')) Can reject multiple number types so you can tune the form input to accept only landline or only mobile, or whatever combination you want. Corrects the errors found in http://djangosnippets.org/snippets/1207/ and adds extra functionality and detail to the code found at http://djangosnippets.org/snippets/2809/ In particular, this version rejects individual invalid area codes and caters for area codes with mixed-length numbering in fine-grained detail. **Uses info from:** [here](http://www.aa-asterisk.org.uk/index.php/Regular_Expressions_for_Validating_and_Formatting_UK_Telephone_Numbers)
