Mysql database migration failing on Rails - mysql

Question

I have this migration file:
class InitialDigitizationWork < ActiveRecord::Migration
def self.up
create_table :digitizations do |t|
t.string :submission_code, :null => false
t.timestamps
end
add_index :digitizations, :submission_code, :unique => true
create_table :digitized_pieces do |t|
t.integer :digitization_id, :null => false
t.integer :position, :null => false
t.string :piece_type, :default => "Page"
t.timestamps
end
add_index :digitized_pieces, :digitization_id
create_table :digitized_views do |t|
t.integer :digitized_piece_id, :null => false
t.string :initial_file_name
t.string :attachment_file_name
t.string :attachment_content_type
t.integer :attachment_file_size
t.datetime :attachment_updated_at
t.integer :position, :null => false
t.boolean :is_primary, :default => false
t.timestamps
end
add_index :digitized_views, :digitized_piece_id, :null => false
end
and it fails on the last line:
-- add_index(:digitized_views, :digitized_piece_id, {:null=>false})
rake aborted!
StandardError: An error has occurred, all later migrations canceled:
Unknown key: :null. Valid keys are: :unique, :order, :name, :where, :length, :internal, :using, :algorithm,
Anyone have any idea what is going on?
What's annoying here is that since the last line fails, I can't rerun the migration again because the table on top digitizations exists. I know how to use Postgresql and access the specific table that is created specified by this yml file:
#SQLite version 3.x
#gem install sqlite3-ruby (not necessary on OS X Leopard)
development:
adapter: mysql2
database: arthouse_development
username: root
password:
host: localhost
port: 3306
#socket: /tmp/mysql.sock
legacy_development:
adapter: mysql2
database: arthouse_legacy_development
username: root
password:
host: localhost
port: 3306
Anyone know how I can console into the database here?
Anyone know what might be going on? This is my first time using mysql and could use some help.
also when I type in mysql this happens:
mysql
ERROR 1045 (28000): Access denied for user 'jwan'#'localhost' (using password: NO)
but this works:
mysql -u root
Do I have to do that everytime?

Ok so here is what you need to do:
First rollback your last migration so that you begin on a clean slate:
rake db:rollback
Then remove the default=> null constraint on your indexes. The error message states explicitly that it's not a known key:
Unknown key: :null. Valid keys are: :unique, :order, :name, :where,
:length, :internal, :using, :algorithm,
Then rerun the migration:
rake db:migrate
