I am following video tutorials for rails.

I am a part where i am suppose to write "scaffold :album" inside admin_controller.

"class AdminController < ApplicationController

  scaffold :album end "

I did that but i get this error "undefined method `scaffold' for AdminController:Class"

What is going on? i am running rails 2.3.5

thanks

Scaffolding was pulled out into a plugin in Rails 2.0 In order to follow that tutorial, you'll need to install it:

script/plugin install scaffolding

However, that tutorial seems pretty out of date. You might want to find a newer one.

Hi, I would recommend using the following link to learn Rails:

http://guides.rubyonrails.org

Good luck,

Is the tutorial telling you to put that code in the AdminController? It is my guess that the code is based on a plugin or gem. Have you included all the proper plugins and gems?

It says "ruby: No such file or directory -- script/plugin (LoadError)"

Scaffold (in the controller) used to be part of Rails. It was removed in 2.0. The original poster should find a current tutorial!

Best,

Are you inside of your project directory when running that command?

yeah i guess so and i cant find a way to get around it. I am a visual learner and these videos help me understand better.

He makes the databases manually in cmd. then db:migrate and then he goes to the admin_controller.rb and put "scaffold :albums" and everything works. when i do the same thing i get "unexpected action view....."

Can you not install the plugin for some reason? Alternatively, you could always install the version of rails that he is using, which must be a pre 2.0 rails.

Bad idea. Scaffolding is best avoided.

No, please don't do that. Learn the current version of Rails. The Rails Guides and Railscasts should get you started.

Best,

I entirely agree, and we’ve all recommended the same, but he seems pretty set on using these certain tutorials :slight_smile:
