This is something I’ve just seen pop up… wondering if anyone else has seen this and has an idea about what might be causing it?
After successfully running rake db:migrate and creating all my tables, I am no longer able to migrate back down. Any calls to rake db:migrate version=0 result in absolutely nothing happening. The only solution I have is to drop all of the tables or drop and recreate the database through MySQL… A migrate then works as expected to create the tables, but then I cannot go back down.
I first noticed this on Ubuntu 6.10 with MySQL 5… but then it happened at PlanetArgon, and then on a Mac that one of my students users. I primarily develop on Windows and so I’ve never seen this before.
Is this a known bug? Is there something we’re missing with the MySQL configuration? I get no error messages… it just runs the task and does nothing.
