Grails object relational mapping (GORM) is one of the most powerful features of the Grails framework. Project bootstrapping and CRUD scaffolding are nice things to get you started, but GORM continues to pay off throughout the development of an application. Even maintenance tasks become simpler and more fun with GORM.
In this presentation we’ll discover what GORM is and what it does for us. We’ll cover dynamic domain class methods, dynamic finders, one-to-many and many-to-many relationships, Hibernate Criteria Builders and more. We’ll also take a look at some things to watch out for since, after all, this is Object Relational Mapping we’re talking about.
Grails is a full stack web development framework that enables you to build complete web applications in a fraction of the time and with less code than other frameworks.
In Grails: A Quick-Start Guide, you'll see how to use Grails by iteratively building an unique, working application. By the time we're done, you'll have built and deployed a real, functioning website.
Along the way, we'll learn about domain classes, controllers, and GSP views. We'll see how Grails allows us to use powerful frameworks like Spring and Hibernate without even knowing it.
Using this hands-on, pragmatic approach, we'll explore topics such as AJAX in Grails, custom tags, and plugins. We'll dig into Grails' powerful view technology, Groovy Server Pages, and see how we can easily leverage the help given to us by scaffolding to create custom user interfaces faster than you would have thought possible.
With Grails, you can get a lot done with little effort. With this book, you'll get a lot done as well. It's time to bring the fun back into web programming. Get started with Grails today.
