So this is my first real Ruby on Rails project. I've learned my lesson -- I didn't make all changes using migrations so things are a bit messed up.
What's the best way to start over with new migration files and rebuild the schema, etc? My project is too far along to rebuild the entire project, but not far enough along to where I care about losing the migrations I have thus far. I also don't mind losing the data in the database. I was trying to rollback to the beginning but some of it is failing.
I know this is a bad state to be in, but lesson learned.
EDIT: I just deleted all the migrations files and rebuilt the schema file with db:schema:dump. I assume this puts me in a clean state with my existing database, just lost migrations.

You can rollback your migration by using rake db:rollback with different options. The syntax will be different according to your requirements. where n is number of migrations to rollback, counting from latest migration. where xxxxx is the version number of the migration.
just use rake db:reset , that will drop your database (same as undoing all migrations) and reset to the last schema. UPDATE: a more correct approach will be using rake db:migrate:reset . That will drop the database, create it again and run all the migrations, instead of resetting to the latest schema.
db:reset: Resets your database using your migrations for the current environment. It does this by running the db:drop , db:create , db:migrate tasks. db:rollback: Rolls the schema back to the previous version, undoing the migration that you just ran. If you want to undo previous n migrations, pass STEP=n to this task.
To delete a migration created using Mover, do the following: Click Migration actions. From the dropdown menu, select Delete migration.
if you want to migrate some steps back you can
rake db:rollback STEP=2
That command will migrate your database 2 migrations back. If you need more help with rake commands, jus type
rake -T
That command will list all the tasks you have in you application.
