Ruby on Rails: Training and Skills to Build Web Applications

Generate a Rails controller for pages with about and contact, then launch the Rails server and view them at localhost3000/pages/about, and /pages/contact, editing content in Sublime Text.

Add navigation links between the about and contact pages in a Rails app, and move common code into the application layout with yield so it applies to all pages.

Learn how to install the bootstrap-sass gem in a Rails app, run bundle install, restart the server, and set up bootstrap imports via custom.css.scss and application.js.

Implement a Bootstrap navigation bar at the top, simplify the code by removing dropdowns and search, and wire links to about, contact, and home via the application layout.

Learn to style Rails forms with Bootstrap by applying form-control and form-group, updating buttons and links, and wrapping content in a container for a cohesive listing interface.

Install paperclip and ImageMagick to enable image uploads for listings in Rails; add the gem, bundle install, restart the server, and install ImageMagick on Mac or Windows.

Set up paperclip in a Rails app to attach and display listing images by adding migrations, updating the listing model and controller, and modifying views to upload and show images.

Format listings with Bootstrap's grid system to create a responsive 4-per-row layout using column md 3. Build a two-column show page with thumbnails, listing name, and price formatted as currency.

Learn to clean up page design using css and bootstrap, customize body and navbar styles with selectors, and apply nth-child layouts to arrange product listings.

Learn to save and share Rails projects by using Git and GitHub, creating repositories, and managing SSH keys to authenticate and upload code.

Set up a GitHub repository, link it to your Rails app, and practice saving versions with git status, git add, git commit, and git push for continuous code versioning.

Protect sensitive account data in a Rails app by using the Figaro gem to store secrets in config/application.yml and ignore them with gitignore, then deploy securely to Heroku.

Tailor Dropbox usage by adding environment-specific Paperclip settings for development and production. Ensure local host uses local files while Heroku pulls images from Dropbox, and ignore /public/system to avoid uploads.

Install devise to enable user authentication in your Rails app, configure urls, flash messages, and migrations, and test sign up, sign in, and profile edits.

Replace html links with Rails link_to and rake routes, and use user_signed_in? to conditionally show sign in, sign up, or sign out and edit profile links.

Learn to implement validations in Rails, enforcing presence for user names and listing attributes, apply numericality constraints for prices, customize Devise messages, and style errors with Bootstrap alerts.

Enforce user permissions with devise by authenticating users, using before_action to restrict sensitive actions to owners, and conditionally displaying links and URL access.

Link orders to listings by updating the controller, routes, and forms to populate listing_id, buyer_id, and seller_id, with authentication, a buy now button, and deployment via git and heroku.

Create two order history pages in Ruby on Rails by adding routes and controller actions for sales and purchases, and building views to display orders with images, prices, and dates.

Add navigation links for sales and purchase histories in the Rails app, implement Bootstrap dropdown menus in the nav bar, and restrict order history actions to new and create.

Install and configure Stripe in the Rails app, including the Stripe gem, Figaro for test and live keys, and Stripe.js with a meta stripe-key in the layout.

Update the order form to collect credit card number, CVC, and expiration date using Stripe and Rails, with Bootstrap grid layout to display fields side by side.
