Learning Laravel's Eloquent

By: Francesco Malatesta

Overview of this book

<p>Learning Laravel's Eloquent starts off by taking you through setting up your first project and guiding you in creating a perfect Laravel environment. You will learn how to build the right database structure with the Migrations system and the Schema Builder class. Next, you will be introduced to the main element of Eloquent: the model. After treating the model as a single, isolated entity, you will learn how to create relations between them. You will be taken through organizing, filtering, and sorting your data with collections. You will then learn to enhance an application with new features using events and by creating new observers. Towards the end of the book, you will discover how to install, configure, and use the Eloquent ORM without Laravel. The book concludes by walking you through how to deal with complex problems and build advanced and flexible systems.</p>

Summary

We did it!

We prepared everything that is needed to work with Laravel and Eloquent. We set up a local development server, learned the basics of Composer to correctly manage our dependencies, installed a couple of more useful tools, and, finally, successfully configured our database connection. Not bad for the first chapter, huh?

However, we have just begun, and our journey inside Eloquent is at the very beginning. We are ready to leave our safe house, go into the darkest corner of the Eloquent ORM to explore it, and understand all of its secrets.

It will be a great ride. And now, let's explore our first topic on our way: the Schema Builder and the migrations system, to build the perfect database!
