Can I get down now dad?

Tramps like us, baby we were born to code

Digging the crazy Grails thing

So here goes, my first Grails app. A simple todo list

First create me an application with: grails create-app todo

Then create a domain class with: grails create-domain-class and tell to create a class called todo.

Edit the domain class, add some fields and constraints as follows:

class Todo {

String description
String type
Date dueDate

static constraints = {
description(unique:true,,blank:false,length:5..30)
type(nullable:false,blank:false,inList:[’work’,'private’])
}
}

Then generate a controller with: grails create-controller and tell it to use Todo.

Finally edit the controller class TodoController.groovy an tell it to dynamically generate the scaffoled code based on the Todo domain class.

class TodoController {

def scaffold = Todo
}

And with just that tiny bit code I have a running app. I can test it locally and when I am happy create a war file with grails war.

Finally, and wondefully I can just upload this to my tomcat server and it works. See the demo app here.

There is a very real chance I may wet my pants.

Final note, the database is just a in memory db so things will disappear.

    All of my code is within the Grails app mduole, so can’t say I’ve come across that.One thing that comes to mind is whether IDEA is generating a jar file for your Java mduole, and placing it within the grails app.. IDEA probably delegates to the grails run-app’ command, and probably requires all of the classes/jars to be available on the filesystem in the standard grails app structure.
