Overview of this book

Go Programming – From Beginner to Professional is a comprehensive guide that takes your proficiency in the Go programming language from novice to expert. Starting with fundamental concepts, this book covers variables, command-line tools, and working with data before delving into advanced concepts, including error handling, interfaces, and generics, harnessing Go’s latest features through hands-on exercises. Along the way, you’ll learn to structure projects using Go modules, manage packages effectively, and master debugging techniques. As you progress, you’ll get to grips with practical application-centric aspects such as command-line programming, file manipulation, and working with SQL databases. Additionally, the book explores web server development, RESTful APIs, and utilizing the Go HTTP client to interact with web applications. Further enhancing your Go skills, you’ll learn concurrent programming, testing methodologies, Go tools, and how to deploy applications in the cloud. Throughout the book, you’ll uncover Go’s hidden gems and gain insights into time manipulation, best practices, and more. By the end of this book, you’ll have worked through practical exercises and activities that’ll equip you with the knowledge and skills needed to excel as a proficient Go developer, primed for success in real-world projects.

Adding users with GORM

So far, we’ve interacted with the database by writing some SQL queries directly. What we’ve done is create and run Go code, which was used to then run SQL code. This is perfectly fine, but there is also a way to run just Go code to interact with a SQL database. On top of this, the data that we are storing in the database will then be unwrapped into Go variables, and the content of a row might define the values of an instance of a Go struct. What we can do to improve and simplify the whole process is abstract the database even more and use an object-relational mapper (ORM). This is a library that matches the tables and their relations as Go structs so that you can insert and retrieve data the same way you would instantiate and delete any instance of a Go struct. An ORM is not generally part of a language, and Go does not provide one by itself. There is, however, a set of third-party libraries, one of which is the de facto ORM for Go, and this is...
