I am new to Rails and Ruby, and to OO languages, and seem to be making a very silly mistake somewhere here. Can anybody help? I am trying to write an application which involves ''exercises'', each of which consists of several ''templates''. This is based on MySQL tables with these names. I have models and controllers, built with the Rails Scaffold, for both

OK so I''ve been trying to follow the tutorial here: http://rails.homelinux.org/ When I simply do "scaffold: category" in the controller.rb, everything works fine. BUT after I generate the controllers and other files using scaffold AS A SCRIPT (script/generate scaffold categories), DESTROY (or DELETE) does not work for any record in a table. This is the error I got: Processing

Apparently a scaffold creates at least one instance variable for views to use, and if I override the scaffold then I must also explicitly create that instance variable for the view. I''d like to know exactly what work is performed by the scaffold so that I can know this when over-riding the view. (OR, is it that the controller makes these variables available by default?..)

Hello, I have been experimenting with Single Table Inheritance as described in the More Active Record chapter in Agile Development with Rails. I have started with an object model with three classes x, y and z (for brevity), where y < x and z < y. (I will want to extend this model further to subclass y with other classes.)

Hello there! This is my first post! ;) I''m starting on ruby on rails, so I have many doubts about it! I''m trying to create a system that uses categories/subcategories.

Then I erased all of that and tried rebuilding the program using the ruby script/generate scaffold Item (and category) command. Now the templates look like " <% for

Allo, Just started playing around with RoR/scaffolding and have been impressed so far. However, it seems to create a 1:1 relationship between Controllers and Models and the basic CRUD actions -- I need to CRUD two models from the same views and actions. I have: Book model Book controller, with create/edit/show/destroy/list actions and the scaffold-gen''ed views. Category model Category
