Estoy tratando de seguir las instrucciones del libro "Head First Rails" y en la página 50 dice crear un modelo pero no puedo crear un modelo usando el comando rails.carriles generan modelo
Cuando escribo esto en este indicador: localhost: ~ $ hogar
rails generate model ad name:string description:text price:decimal seller_id:integer email:string img_url:string

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.

estoy utilizando rieles -v 3.2.8 y Ruby 1.9.3p125
¿Usted hizo un cd en su directorio de proyectos de rieles? – PeterWong
Creo que ese puede ser el problema. No tengo un dir de proyecto El libro está escrito para la versión 2.1 de los rieles. En este tutorial debía crear un directorio usando 'rails mebay', pero ese comando no funciona en Rails 3.2.8. Se supone que no debo usar 'rails new mebay' porque se supone que debo crear manualmente los modelos y los controladores. Creo que falta un paso en el libro. – Livi17
