How can I programmatically obtain the max_length of a Django model field?

Say I have a Django class something like this: class Person(models.Model): name = models.CharField(max_length=50) # ... How can I programatically obtain the max_length value for the name field?
Person._meta.get_field('name').max_length will give you this value. But having to use _meta suggests this is something you shouldn't do in normal usage. Edit: as Carl pointed out, this naming is misleading and it does seem quite acceptable to use it: http://www.b-list.org/weblog/2007/nov/04/working-models/ Read more at Django Docs: https://docs.djangoproject.com/en/dev/ref/models/meta/#django.db.models.options.Options.get_field
