ActiveRecord Aggregations let you use composed_of to combine columns into a single attribute using a Ruby object.
Rails' ActiveRecord supports virtual generated columns in the database. For example, you can use these for converting numbers like degrees Celsius to Fahrenheit. These columns are saved with the regular table data and allows you to query against them.
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.
Our first step in building any application is designing what database models we will need to store our data.
Since we're planning to share passwords with multiple users, we need to use a join table to associate the password with users. We'll explore how to set this up and create records using the join table and has_many through association
Errors can come up in many different ways. This episode, we'll look at how we can improve error handling in the noticed gem to cleanly handle issues with ActiveRecord without negatively affecting
Did you know serialize can be used for more than saving Ruby hashes as JSON or Yaml in your db? You can take any attribute and convert it to an object seamlessly with Rails using serialize and custom coders.

Modules and concerns provide a way to make functionality reusable across your Rails application and other apps. In this lesson, we'll show you how we can refactor our comments functionality to add a feature to any resources in Rails.
Complex queries can slow your page rendering down. We can now run long queries in parallel with Rails 7's load_async method in ActiveRecord to speed up page rendering.
Using Signed GlobalIDs, we can create polymorphic select boxes in Rails to easily choose a record of any type. This is also secured by using signed global IDs to prevent tampering by malicious users.
Nested comment threads pose a lot of unique challenges. One of these is deleting comments because you can easily lose the child comments or context. We'll take a look at a couple great ways of handling this.

With Rails 6.0, you can now define multiple primary and replica databases, define separate migrations for each primary database, and configure each model to read and write from different databases.
Custom ActiveRecord validations are easy to make and they're implemented exactly the same way as the built-in Rails validations. It's super handy to be able to add nice, clean validations that you can repeat throughout your apps.
