20 Scaffolding
Scaffolding lets you generate some basic CRUD interfaces for a domain class, including:- The necessary views
- Controller actions for create/read/update/delete (CRUD) operations
build.gradle.dependencies { // ... runtime "org.grails.plugins:scaffolding" // ... }Static Scaffolding
Grails lets you generate a controller and the views used to create the above interface from the command line. To generate a controller type:grails generate-controller Book
grails generate-views Book
grails generate-all Book
grails generate-all com.bookstore.Book
Customizing the Generated Views
The views adapt to Validation constraints. For example you can change the order that fields appear in the views simply by re-ordering the constraints in the builder:def constraints = {
title()
releaseDate()
}inList constraint:def constraints = {
title()
category(inList: ["Fiction", "Non-fiction", "Biography"])
releaseDate()
}range constraint on a number:def constraints = {
age(range:18..65)
}def constraints = {
name(size:0..30)
}
