I'm using MigratorDotNet to manage Rails-style migrations for my web app. I have a workflow where, if I delete all the tables in the database, I can access an installation view that will run MigratorDotNet and create all the necessary tables.
This works locally. For some reason, when I upload my code to my Arvixe hosting, the migrations just never run. I get this odd error:
There is already an object named 'SchemaInfo' in the database.
This is odd because, prior to running migrations, I manually deleted all the tables in the database (to make sure it wasn't left over from a previous install).
My code essentially boils down to:
new Migrator.Migrator("SqlServer", connectionString.ToString(), migrationsAssembly).MigrateToLastVersion();
I've already verified by logging that the connection string is correct (production/hosting settings), and the assembly is correctly loaded (name and version).
Works locally, but not on Arvixe. How do I troubleshoot this?
This is a dark day.
It turns out (oddly) that the root cause was my hosting company used a schema other than dbo
for my database. Because of this, the error message I saw (SchemaInfo already exists
) was talking about their table.
My solution, unfortunately, was to rip out MigratorDotNet and go with FluentMigator instead. not only did this solve the problem, but it also gave me a more intelligible error message (one referring to the schema names).
While it doesn't seem possible to auto-set the schema, and while I need to switch the schema on my dev vs. production machine, it's still a solvable problem (and a better API, IMO). I googled, but did not find any way to change the default schema in migratordotnet.
