Is there an easy way to populate SlugField from CharField?
for Admin in Django 1.0 and up, you'd need to use
prepopulated_fields = {'slug': ('title',), }in your admin.py
Your key in the prepopulated_fields dictionary is the field you want filled, and the value is a tuple of fields you want concatenated.
Outside of admin, you can use the slugify function in your views. In templates, you can use the |slugify filter.
There is also this package which will take care of this automatically: https://pypi.python.org/pypi/django-autoslug
Outside the admin, see this django snippet. Put it in your .save(), and it'll work with objects created programmatically. Inside the admin, as the others have said, use prepopulated_fields.
