In my previous GORM related article, "Association Types in GORM", I have described how to create different types of relationships using Grails ORM. In this article, I would like to talk about several advanced GORM features that may help you in the development process, such as:
This example shows how to use pagination and sorting with many-to-many relationship in Grails.
Assume you have a page with pagination that displays some objects table (selected from DB with GORM criteria) in your Grails application. If you want to know total number of possible results (as if there are no pagination parameters), you can do it in this way:
Hi, guys, today we’re gonna talk about the really interesting and tricky Grails task, implementation of the custom sorting.
It’s a pretty often appearing situation, when you need to sort the list of items, basing on the values that can only be calculated, and that are not persisted in the db.
I know what you might say, - "Hey, why don’t you just use transient properties for that?"
Modern web applications are counting on the big amount of users, so efficiency is a very important aspect of a web development. Today we’ll talk about the ways to increase efficiency of the web application, developed on the Grails platform.
