Menu
I have a tasks class, which has a date field. In my view file, I have this line of code :
<g:textField name="date" value="${tasksInstance?.date}" id="datePicker" />
And using the jquery ui plugin, I added this code to my <head> tag :
<g:javascript>
$(document).ready(function()
{
$("#datePicker").datepicker({dateFormat: 'mm/dd/yy'});
})
</g:javascript>
But when I save the date field, I get the following error:
Property date must be a valid Date error
Tasks.groovy
package mnm.schedule
class Tasks {
static belongsTo = [ user : User, project: Project ]
String reason
boolean completed
String title
String description
Date date
static constraints = {
user(nullable:false)
completed(nullable:true)
title(nullable:false)
description(size:1..500,nullable:false)
reason(nullable:true)
}
String toString(){
this.title
}
}
And controller action code is :
def save() {
def adminProject = params.managersProject
def foundProject = Project.findByNameLike("$adminProject")
def tasksInstance = new Tasks(params)
foundProject.addToTasks(tasksInstance)
if (!tasksInstance.save(flush: true)) {
render(view: "create", model: [tasksInstance: tasksInstance])
return
}
redirect(action: "show", id: tasksInstance.id)
}
How to recover from this?

I assume you're getting a String like '02/16/2012'? You could just call:
params.date = Date.parse( 'MM/dd/yyyy', params.date )
Before creating the Task object...
There's probably an automatic way of doing this in Grails as well using PropertyEditorSupport
Also, in grails 2.0, you can do:
def date = params.date( 'myVar', 'MM/dd/yyyy' )
To parse the date param out of the params object
