Ruby On Rails: Create Models View And Controller from existing database

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

Well this goes against principles. The better you have to do, if you want a quick bootstrap for your application is replicate the models you have on your database and use scaffolding.Remember that Rails use a LOT of conventions, and if you decide not follow you'll have a lot of trouble.

Check this guide if you need help.

This is how you can do that -

Try:

rails g scaffold myscaffold

This will generate the files:
