Hi everybody,
I'm looking for a way to migrate SQLAlchemy based database easily. I
found Migrate, but finally it's almost the same as doing the migration
by hand.
If this doesn't exists, do you think that it would be hard to do a
simple migration tool which would :
- Add/Delete columns from DB if they are not anymore in the models
(With a confirmation for deletion)
- Add/Delete constraints/sequences on table if they are not on the
model too
We could also imagine a way to :
- Handle column rename, with data copy from one to another
- Handle column type change, with proper data conversion
Of course, such a system can't be 100% automated, that's not the goal.
Human interventation will be needed, but it might be more simpler for
simple cases than Migrate.
