There is also an app called django-autoslug which provides a field type AutoSlugField. Using that, you could have:

class Something(models.Model):
    title = models.CharField(max_lenght=200)
    slug = AutoSlugField(populate_from='title')
    ...

This AutoSlugField has many nice features, such as generating a slug so that it is unique either globally of combined with some other field (maybe a category or the year part of a DateTimeField).

See http://pypi.python.org/pypi/django-autoslug for further details.

There used to be a prepoulate_from option for the SlugField up to 0.96. It became an admin option after that. See here for reference on that.

Alternatively, you could override the model's save method to calculate the value of the slug field on save().

This question may be helpful, too.
