Anyone can create, edit, or delete a blog post in our Rails app currently. In this lesson, we'll add authentication so only allowed users can do those actions.

We want to be able to delete blog posts we no longer want. We'll learn how to delete blog posts and refactor our code in this lesson.

Implementing Edit and Update actions are straightforward now. We can reuse what we've learned with New and Create and reuse some of the logic to edit and update database records in Rails.

Handling form submissions with Rails teaches us about strong parameters and saving data with our Rails models into the database.

We now want to create new Blog Posts in our Rails app, not directly in the database. To do this, we're going to start by building a new action and form for inputting data for our Rails model.

We need a way to view individual Blog Posts on their own URLs now. That's where our Show action comes into play and we will learn how to build that in this lesson.

An index page allows us to display all the blog posts in our database. We will learn how to setup routes that point to controllers and actions that render HTML.

The first thing we need is a database table to store our blog posts. We create a Rails model (the M in MVC) to create the database and a Ruby class for us to interact with the database table.

Now that we've created a new Rails app, let's take a look at the files generated and learn what they do

We're going to build a Blog with Ruby on Rails so let's start by making sure we have everything installed and create our new Rails app
