Question

Ruby on Rails apparently changed the syntax for creating scaffold. I’m trying an example that says to use:

ruby script/generate scaffold tale tale
ruby script/generate scaffold genre genre

The database tables are named “genres” and “tales”. When I don’t repeat, it works ok:

ruby script/generate scaffold tale
ruby script/generate scaffold genre

However, the localhost/genre does not work as described in the book. I can access the page using localhost/genres, but when I select “create” the page only shows:

New genre

(Create button)

Back

Am I missing something that is required to show the input field?
“show create table genres” shows the table is defined as:

CREATE TABLE `genres` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `genre_name` varchar(25) NOT NULL,
  `description` varchar(100) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |

Answer 1

for the scaffold to generate the input fields on the form, you should pass them in the command itself.

ruby script/generate scaffold genre genre_name:string description:text

that will generate the same db table you show and with the proper input fields on the views.
