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.
Defining Our Models
In this lesson, we'll walk through the process of defining all our database tables and columns as models and properties within our application.
Introducing Lucid Models
In this lesson, we'll introduce models using the Lucid ORM. We'll learn how we can map database columns to our model properties and specify special behavior for our date time columns.
The Flow of Migrations
In this lesson, we'll learn about the various migration-based commands made available by the Ace CLI and how they interact with our migration files. We'll use these commands to run, rollback, and refresh our migrations against our database.
Introducing and Defining Database Migrations
In this lesson, we'll introduce database migrations. We'll learn what they are, why they're great to have, and how we can create and use them to define our database tables and their columns.
Understanding our Database Schema
In this lesson, we'll walk through how to understand a database schema diagram. We'll then discuss the schema we'll be working with throughout this series; describing the tables, columns, data types, and relationships.
Configuring Lucid and our Database Connection
In this lesson, we'll learn how we can configure Lucid to use a different driver other than SQLite; PostgreSQL is shown but MySQL and MSSQL are much the same. Then, we'll set up our connection details so that we can successfully connect to our database.
Let's Learn AdonisJS 6 #2.11
Defining A Structure for our Movie using Models
In this lesson, we'll introduce the concept of models by using one to define the properties our movies should contain. We'll then stub some methods that will mock calls we'll later be able to use to load data from our database.
Model vs Database Query Builder
In this lesson, we'll take a look at the differences between the model and database query builders.
A Deep Dive Into Mixins & Compose
In this lesson, we'll walk through what mixins are and how they work by first inspecting them as plain objects then working our way into classes then finally TypeScript. We'll then implement mixins via AdonisJS' compose utility.
Limiting, Sorting, & Pagination with the Query Builder
In this lesson, we'll take a look at the various options we have to limit results when using the query builder including first, firstOrFail, limit, and pagination. We'll also learn how we can sort our results.
Intro to the Query Builder & It's Where Statements
In this lesson, we'll introduce the query builder. We'll spend most of our time looking at its various where statement options and how we can use them to build queries.
AdonisJS Quick Tip #17.0
How To Use AdonisJS Model Hooks To Log All User Actions
In this lesson, we’ll be taking a look at how we can log any and every user action performed against our AdonisJS models.
