Ruby on Rails+MySQL

Sebesta corvette example In rails_apps create a directory (car_app), change to this dir and run rails (rails cars) Rails_apps Car_app cars

Go to cars dir and type: ruby script/generate controller main C:\InstantRails\rails_apps>mkdir car_app C:\InstantRails\rails_apps>cd car_app C:\InstantRails\rails_apps\car_app>rails cars create create app/controllers create app/helpers create app/models create app/views/layouts create config/environments create components create db create doc create lib create lib/tasks … C:\InstantRails\rails_apps\car_app>cd cars C:\InstantRails\rails_apps\car_app\cars>ruby script/generate controller main exists app/controllers/ exists app/helpers/ create app/views/main exists test/functional/ create app/controllers/main_controller.rb create test/functional/main_controller_test.rb create app/helpers/main_helper.rb C:\InstantRails\rails_apps\car_app\cars>

Building tables I used phpmyadmin to build the tables. The text uses scripts in mysql to generate the tables.

main/welcome

Requesting all coupes from 1970 to 2005

Source files for cars app (with little guidance on where to put them)

Where to put the files Put controllers in controllers Put rhtml (or directories with display.rhtml) in views Models dir 

controllers

views

Create a new database, cars_development

Phpmyadmin from rails

Looking at a table

An app dir in a rails application

Trying to register to be a member returns “user created” if no errors

User “secretariat” created

Secretariat in db

So what all is in this app?

application.rb # Filters added to this controller apply to all controllers in the application. # Likewise, all the methods added will be available for all controllers. class ApplicationController < ActionController::Base # Pick a unique cookie name to distinguish our session data from others' session :session_key => '_rail_space_session_id' end

site_controller class SiteController < ApplicationController def to 'My' RailSpace!" end def 'My' RailSpace!" end def for 'My' RailSpace!" end

user_controller class UserController < ApplicationController def index end def = "Register" if = User.new(params[:user]) render :text => "User created!" end

app/models- users.rb in notes
