每次都會忘掉

氣死我了, 每次都會忘掉怎麼用ruby on rails, 老了, 還是寫下來的好

1. rails testrails
2. in config\database.yml
development:
adapter: mysql
database: account
username: root
password:
host: localhost

test:
adapter: mysql
database: account_test
username: root
password:
host: localhost

production:
development


3. ruby script\generate model user
4. in db\migrate

class CreateUsers < ActiveRecord::Migration
def self.up
create_table :users do |t|
t.column :login, :string
t.column :password, :string
t.column :created_at, :datetime
end
end
def self.down
drop_table :users
end
end

5. rake db:migrate

6. ruby script\generate controller user

7. scaffold in controller
class UserController < ApplicationController
scaffold :user
end

8. ruby script/server
9. browse to http://localhost:3000/user

10. ruby script\generate scaffold user
11. edit those controllers
12. browse to http://localhost:3000/users
