Iniciando com Ruby on Rails

Pessoal estou iniciando meus estudos com Ruby on Rails, e ao executar o comando do rake: db:migrate, esta gerando o erro abaixo.

Alguém já passou por essa situação.

Valeu.

manda o código da sua migration também.

Cara não use essa versão do JRuby, ele já ta na versão 1.4 se ta usando a 1.1. Ou use o Ruby puro. Acho que teu problema é biblioteca desatualizada.

class CreateContexts < ActiveRecord::Migration def self.up create_table :contexts do |t|t.column :name, :string end end def self.down drop_table :contexts end end

Cara... teste assim

create_table :contexts do |t| t.string :name end

Cara valeu, mas o erro continua..
