Russel, I'm only a non-programmer user, but just curious question:
why you (all of core developers) implement the schema evolution in
the self model that is evolving and not outside the model?
Why not if you have:
from django.db import models
class Poll(models.Model):
question = models.CharField(maxlength=200)
pub_date = models.DateTimeField('date published')
author = models.CharField(maxlength=200)
and you want to rename 'pub_date' to 'publication_date', add 'purpose'
field, and modify DateTimeField to DateField why not:
class Migration(models.Migration):
Poll.changes = {Poll.rename(pub_date, Poll.publication_date)
Poll.addfield(purpose =
models.CharField(maxlength=100)),
Poll.modify(publication_date =
models.DateField("date published")}
Well, in more pollite syntax but you understand me
Migration migrates Poll in database and writes models file
A desktop user have a evolutioned model
Thanks,
Xan.
