SWorD

SWorD (Social Web of real Domotics) is a prototype social network where users, homes, providers, devices and appliances can interact and act in a "smarter" way, by talking each other and thus lowering the technical knowledge to use home automation and domotics systems.

LAB2

1. Creation of static pages for our social network: home, about and contact

• rails generate controller Pages home about contact (or from the RubyMine menu Tools > Run Rails Generator...)

2. Add title to HTML files: "SWorD | Page name"

• by using the provide method in each view, i.e., <% provide :title, 'Page name' %>
• by editing the title tag in app/views/layouts/application.html.erb, i.e., <title>SWorD | <%= yield(:title) %>
• learn more about provide at http://api.rubyonrails.org/classes/ActionView/Helpers/CaptureHelper.html#method-i-provide

3. Add an helper to avoid wrong rendering if the page title is not declared

• in app/helpers/application_helper.rb
• by editing the title tag in app/views/layouts/application.html.erb

LAB4 - Preparation

1. Fill with some contents all the views

2. Add bootstrap-sass gem to include the Bootstrap framework with Sass support http://twitter.github.io/bootstrap/

• update the Gemfile
• run bundle install

3. Add and fill a custom SCSS file in app/assets/stylesheets

LAB4

1. Move HTML shim, header and footer code in three partials (placed in app/views/layouts/)

2. Update the routes.rb file, according to the table present in the exercise 1 text

3. Update links present in _header.html.erb and _footer.html.erb

4. Add a faq page:

• add a new view called faq.html.erb with a content similar to the other views
• update the Pages controller
• add the corresponding named route to routes.rb

5. Add a Users controller and a page named "new"

• rails generate controller Users new (or from the RubyMine menu Tools > Run Rails Generator...)
• fill the content of the new.html.erb view
• update/add the corresponding named route to routes.rb, mapping it with the signup URI
• update the "Sign Up" link present in home.html.erb

LAB 5

1. Generate the User model, with two attributes: name and email

• rails generate model User name:string email:string (or from the RubyMine menu Tools > Run Rails Generator...)

2. Migrate the model to the database (i.e., create the table and columns corresponding to the User model)

• bundle exec rake db:migrate (or from the RubyMine menu Tools > Run Rake Tasks...)

3. Add some gems to the Gemfile (and perform a bundle install)

• annotate (version 2.5.0) to show some annotations in the Rails models
• bcrypt-ruby (already present, but commented) to have some state-of-the-art hash functions available in Rails

4. Annotate the User model to show a little bit more information

• bundle exec annotate (or add a new configuration of type Gem Command from the RubyMine menu Run > Edit Configurations...)

5. Add debug information in application.html.erb, by using the debug method

6. Add some validations to the User model

• name must be always present (presence: true) and it must have a maximum length of 50 characters (length: { maximum: 50 })
• email must be always present, unique (uniqueness: { case_sensitive: false }) and with a specific defined format (format: { with: VALID_EMAIL_REGEX })

7. Enforce the uniqueness of the email by using a migration

• add an index on the email column in the database

8. Give to the User model a password field

• generate/migrate a migration to add a column to store the password digest (i.e., an encrypted version of the password)
• update the User model with two virtual attributes: password and password_confirmation
• add the has_secure_password method to the User model, to use the authentication system of Rails

LAB 6 - Preparation

1. Add routes for users

• resources :users in config/routes.rb

2. Add a user in the database, by editing the action new in the Users controller

3. Add a new view associated to the Users controller

• create show.html.erb in app/views/users (filled with some contents)
• update the page stylesheet
• add the corresponding action to the User controller (users_controller.rb)

4. Add an helper for using a Gravatar as profile pic for the users (in users_helper.rb)

• update the view responsible of showing users (show.html.erb)
