From Ruby on Rails I've learned about a comfortable and very manageable way to do database migrations.
How would one handle such cases in Qt4? It does not need to be that elaborated as Rails' solution. I'd be fine with running SQL and code snippets to go up or down the version list of my data.
I googled a little bit but there seems to be no standard solution. There even seems to be no one who scratched his head before. It looks like everybody implements their own idea of how to do that.
Is there anyone interested or working on a standard solution and like to share efforts? Or maybe even has a working implementation? I'm thinking of the idea to have something similar like the information_schema table in Rails and let the application run a wizard to up- or downgrade the database (and maybe offer to do a backup/dump first), or as another option just run the migration without wizard, maybe just a handy progressbar.
