63 Model Name In URL

By default, Rails uses the model's id in the URL. What if you want to use the name of the model instead? You can change this behavior by overriding the to_param method in the model. Watch this episode for details.

Cambiamos en index.rhtml

product_path(product)

por

...

y en product.rb añadimos:

def to_param
  "#{id}-#{permalink}"
end

Pero si no queremos el id:

def to_param
  permalink #o el campo que queramos
end

Aunq es más lento.
