Adding attributes into Django Model's Meta class
django, django-models, metadata, python
Solution
I don't know about elegant, but one pragmatic way is:
import django.db.models.options as options
options.DEFAULT_NAMES = options.DEFAULT_NAMES + ('schema',)
Obviously, this would break if Django ever added a 'schema' attribute of its own. But hey, it's a thought...you could always pick an attribute name which is less likely to clash.
Problem
I'm writing a mixin which will allow my Models to be easily translated into a deep dict of values (kind of like .values(), but traversing relationships). The cleanest place to do the definitions of these seems to be in the models themselves, a la: ``` class Person(models.Model, DeepValues): name = models.CharField(blank=True, max_length=100) tribe = models.ForeignKey('Tribes') class Meta: schema = { 'name' : str, 'tribe' : { 'name' : str } } Person.objects.all().deep_values() => { 'name' : 'Andrey Fedorov', 'tribe' : { 'name' : 'Mohicans' } } ``` However, Django complains about my including this in `class Meta` with: ``` TypeError: 'class Meta' got invalid attribute(s): schema ``` (entire stack trace here) Now, I suppose I could elaborately override this in my mixin, but is there a more elegant way of storing this information?
