No se puede convertir el fixnum en una cadena durante el rake db: create (1)

El analizador YAML tiene que adivinar qué tipo de datos es cada valor en su archivo database.yml , sin ninguna otra información contextual.

Como tal, probablemente considera que el valor de tu password de 123 es un número entero.

Tratando de forzar la interpretación de la cuerda:

password: "123"

Acaba de crear una nueva aplicación de blog usando Rails 3.0

mi modelo es simple

class Post < ActiveRecord::Base has_many :comments end class Comment < ActiveRecord::Base belongs_to :post end

Utilicé los comandos: los rieles generan el título del post del andamio: cuerpo de la cadena: texto, etc.

para crear estos archivos.

Ahora quería generar el db usando:

rastrillo db: crear

Me salió el error

rake aborted! can''t convert Fixnum into String

¿Alguna idea de cuál puede ser el problema?

Estoy siguiendo este tutorial: http://sixrevisions.com/web-development/how-to-create-a-blog-from-scratch-using-ruby-on-rails/
