How would you inherit from and override the django model classes to create a listOfStringsField? | 1,126,642 | <p>I want to create a new type of field for django models that is basically a ListOfStrings. So in your model code you would have the following:</p>

So, why not using <a href="http://code.google.com/p/django-tagging/">django tagging</a>?<br />
It works like a charm, you can install it independently from your application and its API is quite easy to use.</p>

Do you use find_packages? This function by default uses the VCS (e.g. subversion, hg, ...). If you don't like it, just write a different Python function which collects only the things you want.</p>
