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.
ActionText builds on top of the ActiveStorage file uploads feature in Rails, so we're going to configure Amazon S3 storage so we can upload files in production
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.
Over time, you'll need to upgrade the Ruby version of your Rails application. For example, a new version of Ruby was released since we started this series that fixes a couple security issues in Ruby so we'll teach you how to upgrade your Ruby version.
Pagination is something we don't need until we publish a lot of blog posts. We can use the pagy gem to add page links to the bottom of our pages and handle thousands of blog posts.
We look at using the built in SimpleDelegator class to easily create decorators for objects.
Blog posts often need cover images for social sharing. In this lesson, we'll add cover image file uploads with ActiveStorage.
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.
URI in Ruby is powerful, but not complete. We can use the PublicSuffix and Addressable gems to take this a step further for parsing domains and subdomains.
The addressable gem adds some nice features over Ruby's built-in URI class, but it doesn't have any helpers for extracting subdomains. In this lesson, we'll add some methods to Addressable to make accessing subdomains easier.
