Lessons
Seeding Movies with One to Many Model Factory Relationships
In this lesson, we'll learn how we can use Model Factory Relationships to create a pool of cineasts to bind to our movies. This will create cineasts bound to many movies as a writer, director, or both.
Defining One to Many Relationships with Lucid Models
In this lesson, we'll learn how to define one-to-many and many-to-one relationships using Lucid Models. We'll also learn how we can specify the columns that should be used for a relationship, allowing us to use one model for multiple relationships.
Cascading and Deleting Model Relationships
In this lesson, we'll learn how to account for foreign key constraints when deleting relationships using our Lucid Models. We'll then learn how we can automatically cascade deletions through to relationships.
Querying Relationships and Eager Vs Lazy Loading
In this lesson, we'll learn how we can query our relationships using our Lucid Models. We'll then learn what the difference is between eagerly loading a relationship (load) and lazily loading a relationship (preload).
Model Factory Relationships
In this lesson, we'll learn how to use relationships with our Model Factories; easing our capabilities to quickly generate fake data with relationships.
Defining One to One Relationships Within Lucid Models
In this lesson, we'll learn how to define one-to-one relationships within our Lucid Models. We'll learn about the belongs to and has one decorators, their options, and types that make this possible.

Generating A Unique Movie Slug With Model Hooks
In this lesson, we'll learn how we can use Model Hooks to generate a unique URL-safe slug based on the movie's title.
Let's Learn AdonisJS 6 #4.16
Querying Recently Released and Coming Soon Movies
In this lesson, we'll learn how to use the Model Query Builder to query our movies that have been recently released. We'll then do a separate query to get movies that are coming soon.

Tapping into Model Factory States
In this lesson, we'll dive a little bit deeper into Model Factories by introducing factory states. We'll also learn how we can use the tap method to alter a factory result prior to it persisting into the database
Let's Learn AdonisJS 6 #4.14
Reusable Query Statements with Model Query Scopes
In this lesson, we'll learn about Model Query Scopes and how we can use them to create easily reusable query statements that we can apply using the Model Query Builder.
Let's Learn AdonisJS 6 #4.13
SQL Parameters and Injection Protection
In this lesson, we'll learn about SQL Parameters, also called query bindings, and how using them helps safeguard our database from malicious attacks attempting to perform SQL Injection.
Let's Learn AdonisJS 6 #4.12
Adding A Profile Model, Migration, Factory, and Controller
Uh oh, a new requirement has come in and now we also need to account for user profiles! In this lesson, we'll learn how we can easily create a new model, migration, factory, and controller for an entity in one fell swoop!
Let's Learn AdonisJS 6 #4.11
Altering Tables with Migrations
In this lesson, we'll learn how to alter our database tables using migrations both while in development, where we can delete our data, and once our data has already hit production where we need to persist all data.
Let's Learn AdonisJS 6 #4.10
Unmapped and Computed Model Properties
In this lesson, we'll learn how to add unmapped and computed properties to our Lucid Models. We'll discuss the differences between a model column, unmapped property, and a computed property.
Querying Our Movies with the Query Builder
In this lesson, we'll introduce both the database and model query builder. We'll learn the differences between the two and the basics of how to use them.
Stubbing Fake Data with Model Factories
In this lesson, we'll learn how we can quickly and easily bulk-create dummy/fake data within our database for each of our Lucid Models using Model Factories
Defining Required Data with Seeders
Our database will have specific, non-changing, roles and movie statuses. In this lesson, we'll learn how we can quickly and easily create these records inside of our database using seeders.
The Basics of CRUD
In this lesson, we'll walk through the basics of creating, reading, updating, and deleting (CRUD) data from our database using our Lucid Models.
