Is there some sort of way to roll back the initialize_project_db script in pyramid?
initialize_db is not a migration script. It is for bootstrapping your model and that's that. If you want to tie in migrations with upgrade/rollback support, look at alembic for SQL schema migrations.
I am a rails developer that is learning python and I am doing a project using the pyramid framework. I am used to having some sort of way of rolling back the database changes If I change the models in some sort of way. Is there some sort of database rollback that works similar to the initialize_project_db command?
