Here’s another piece of info that wasn’t easy to discover using the Google query I expected. If you should ever find yourself needing to explicitly set the migration version that Rails thinks you are at, perform the following steps:
1. Open your Database (using MySQL, this should be something like “mysql -h localhost -u root -p”, followed by “use [database name];” in the MySQL console)
2. Run “Update schema_info SET version=[version number];”
And you’re done!
