Goto command prompt

c:\>cd EMP

u ll see the Folder structure is created for grails project , it follows MVC design pattern,

so u can manage your code properly like we can separate thing, all presentation logic we keep in grails-app/view folder , we can add model class in grails-app/domain folder, controller class added to perform actions on http request/response keep in grails-app/Controller folder, grails provide good command line artifact to perform this action ...

u can simply run c:\EMP> grails run-app

and http://localhost:8080/EMP u will see the index page of create application..

added a domain class

c:\EMP> grails create-domain-class User ->this command is create a User Class .

u can Edit this grails-app/domain/User.groovy class , add attribute

class User{

String userName

String password

static constraints = {}

}

similarly create Controller for User.Class

c:\EMP> grails create-controller User

u can Edit this grails-app/controller/UserController.groovy class ,

class UserController {

def scaffold = User

}


now save this classes and run application

c:\EMP> grails run-app

hit http://localhost:8080/EMP on browser u will see the index page with user controller action link, u can now easily perform Add/Modify/Delete/List feature

That information will form the basis of our domain model, and the various data elements on the form will become the attributes of our domain classes.  Create-Domain-Class racetrack> grails create-domain-class Race class Race { String name Date startDateTime String city String state Float distance Float cost Integer maxRunners = 100000 static hasMany = [registrations:Registration] } racetrack> grails create-domain-class Registration class Registration { Race race String name Date dateOfBirth String gender = 'F' String emailAddress String postalAddress Dat...
