[RAILS] What to do if you get a SQLite3 :: BusyException: database is locked error

This is a workaround that was taken when a new table was created and rails db: migrate was executed during Rails learning, but it was not reflected in the DB (DB Browser for SQlite).

ActiveRecord::Base.connection.execute("BEGIN TRANSACTION; END;")

I entered this command with rails consoloe and it was fixed.
