CRUD new1

In this course, you will learn the fundamentals of Ruby on Rails to build your own application.

You will start by learning how to create a new project, deploy to a Rails server, and the Rails design pattern. After that, you’ll learn how to perform CRUD operations, handle user authentication, and manage sessions.

Once you finish this course, you’ll have the foundations in place to build more complex applications to add to your portfolio.

Introduction to Ruby on Rails

# See https://help.github.com/articles/ignoring-files for more about ignoring files.
#
# If you find yourself ignoring temporary files generated by your text editor
# or operating system, you probably want to add a global ignore instead:
#   git config --global core.excludesfile '~/.gitignore_global'

# Ignore bundler config.
/.bundle

# Ignore the default SQLite database.
/db/*.sqlite3
/db/*.sqlite3-journal

# Ignore all logfiles and tempfiles.
/log/*
/tmp/*
!/log/.keep
!/tmp/.keep

# Ignore uploaded files in development
/storage/*
!/storage/.keep

/node_modules
/yarn-error.log

/public/assets
.byebug_history

# Ignore master key for decrypting credentials and more.
/config/master.key

# README

This README would normally document whatever steps are necessary to get the
application up and running.

Things you may want to cover:

* Ruby version

* System dependencies

* Configuration

* Database creation

* Database initialization

* How to run the test suite

* Services (job queues, cache servers, search engines, etc.)

* Deployment instructions

* ...


# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

require_relative 'config/application'

Rails.application.load_tasks


# This file is used by Rack-based servers to start the application.

# Explanation
## `config/routes.rb`
**Line 4:** We know that `links#index` will serve the `index` view, so you will add `links#index` to be the `root` of your application. This will serve the `index` view at `/` instead of just at `/links/`.
