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
Now that we've created a new Rails app, let's take a look at the files generated and learn what they do
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.
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.
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.
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.
Handling form submissions with Rails teaches us about strong parameters and saving data with our Rails models into the database.
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.
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.
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.
Our blog doesn't look great. We're going to install TailwindCSS so we can easily style our Rails application however we want.
Next we're going to deploy our Rails blog application to production! This is a huge step, but also
Scheduling blog posts to be published in the future is the next feature we're going to add. In this lesson, we'll talk about several options we have to implement this and then choose one to build.
Our scheduled blog posts adds some complexity to our app. In this lesson, we're going to write some tests to make sure that our code does what we want it to do.
Scopes are a way for us to change the way a database table is queried. For example, we can use them to change the ordering of the results so certain records are first.
ActionText is a feature of Rails that allows you to add rich text including file uploads to any of your models. This is a perfect fit for our Blog Posts, so we're going to replace the text column with a rich text field with ActionText.
Rails uses the MVC Pattern. This isn't as scary as it sounds. It's basically a design architecture that gives you 3 primary buckets to help you organize your code.
Processing inbound webhooks can be tricky. In this lesson, you'll learn how receive, verify, and process webhooks in an efficient and well-organized manner.
A lot of developers use link_to and button_to interchangeably. In this lesson, we'll explore when you should use link_to and when to use button_to and the differences between them.
