python - Is there an easy way to populate SlugField from CharField?

Question

class Foo(models.Model):
    title = models.CharField(max_length=20)
    slug = models.SlugField()

Is there a built-in way to get the slug field to autopopulate based on the title? Perhaps in the Admin and outside of the Admin.

Answer 1

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
