You have to create simple model for every table with relations, and then you can

[rails3] > rails generate scaffold_controller Club name:string exclusive:boolean
      create  app/controllers/clubs_controller.rb
      invoke  erb
      create    app/views/clubs
      create    app/views/clubs/index.html.erb
      create    app/views/clubs/edit.html.erb
      create    app/views/clubs/show.html.erb
      create    app/views/clubs/new.html.erb
      create    app/views/clubs/_form.html.erb
      create    app/views/layouts/clubs.html.erb
      invoke  test_unit
      create    test/functional/clubs_controller_test.rb

Alternatively you can try active_admin gem

ActiveAdmin - https://github.com/gregbell/active_admin

rails generate active_admin:resource [MyModelName] 

RailsAdmin is also good enough https://github.com/sferik/rails_admin

You should specify at least 2 rules for your model if it doesn't use rails conventions. Example

class Article < ActiveRecord::Base
  self.table_name "tbl_articles"
  self.primary_key "art_id"
end
