Iniciando com Ruby on Rails

Programação Ruby on Rails
#1

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

(in C:/Documents and Settings/Henrique/Meus documentos/NetBeansProjects/RailsApplication1)

Alguém já passou por essa situação.

Valeu.

#2

manda o código da sua migration também. :wink:

#3

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.

#4 
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
#5

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 [/quote]

Cara… teste assim

create_table :contexts do |t|
   t.string :name
end
#6

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 [/quote]

Cara… teste assim

create_table :contexts do |t| t.string :name end [/quote]

Cara valeu, mas o erro continua…
