A practice Twitter-like project for Rails.

Notes for Ruby Hack Day V

Create new actions in Users controller: login, process_login and logout

The form in login.html.erb

  <%= form_for(@user, :url => { :action => "process_login" }) do |f| %>

Practice how to use 'session'
- In process_login action:
```
`session[:id] = user.id`
```
- In logout action:
```
`reset_session`
```

Create a method, authenticate, in User model for simplifying the code in the controller

  def self.authenticate(user_info)
    find_by_name_and_password(user_info[:name], user_info[:password])
  end

config/routes.rb
```
  root :to => "barks#index"
```

Notes for Ruby Hack Day IV

Add status updating page

  $ rails generate model Bark status:string
  $ rake db:migrate
  $ rails generate controller Barks new

Try belongs_to and has_many
- Bark belongs_to User
- User has_many Barks
Create <select> tag by collection_select(:bark, :user_id, User.all, :id, :name)

We still need to add user_id to make Bark belongs_to User

  $ rails generate migration AddUserIdToBarks user_id:integer
  $ rake db:migrate

Try bark.user.name to feel the magic of Rails!

Notes for Ruby Hack Day II

Start a Rails app

  $ rails new barker
  $ rails generate model User name:string email:string fullname:string password:string created_date:timestamp
  $ rails generate controller Users new index

Create the database for your Rails app. Please refer the list by '$ rake -T'
```
  $ rake db:setup
```
Or
```
  $ rake db:migrate
```

config/routes.rb

  resources :users
  root :to => "users#new"

Seperate your form by
```
  <%= render 'form' %>
```
and create a new .erb file called _form.html.erb
What's the difference between redirect_to and render?
