Introduction

In order to explain how this plugin works we are going to write some code for a dummy example app which contains three type of relations (one-to-many, many-to-one and one-to-one) between four domain classes.

Domain Model

Scaffolding

Grails Project Creation

Plugin installation

Generating domain class model

Let's edit generated domain classes

Company

Customer

Address

Phone

CRUD Company and Customer Generation

Flex compilation

It's time to start up our app-server and navigate our application

open browser and go to http://localhost:8080/gfs-test

Success tips (Important information)

Relations

• many-to-one supports only inPlace:false (this declaration is not required because it's setted as a default)
• one-to-many both cases are supported inPlace:false/inPlace:true.
• one-to-one supports only inPlace:true (this declaration is not required because it's setted as a default).
• If relations are declared as inPlace:true, e.g: Customer <-> Address o Customer -> Phone, the included class (Address, Phone) must define the constraint diplay:false for property that is including "custormer(display:false)". At this moment, this restriction is not valid in generation code time and ends by abort process
• Relations must ever be lazy:false if not, BlazeDS throws a LazyInitialization exception (in future versions we are going to support this feature with DPHibernate or similar).
  

Constraints

• Front-End supported constraints
  • blank, email, size, minSize, maxSize, min, max, range, url, inList
  • For each Front-End constraint, a Flex validator is generated. This avoids user to persist the entity without the need of Back-End validation.
    

• All other constraints (Grails constraints) follows Grails validation way, doing validation on Back-End side which have the responsibility of getting feedback about errors to Front-End. This kind of errors are supported by i18n.
