How to get a DateTime input in a Play! CRUD form? - datetime

Question

By default a java.util.Date field is represented in a CRUD form as a simple "DATE" input.
public class DatedModel extends Model {
public Date creationDate;
in the CRUD admin I see:
creationDate [TEXTINPUT]
yyyy-MM-dd format.
Is there any way to have a DateTime input instead, on selected fields only (not all of them modifying the application.conf date.format)?
Is there a way to affect which "widget" is used for a given field in the 'automated' CRUD admin?

Answer 1

Something like this in your application.conf:
module.crud=${play.path}/modules/crud
date.format=yyyy-MM-dd hh:mm:ss
Then in the model:
package models;
import java.util.*;
import play.data.binding.As;
import play.db.jpa.*;
import play.data.validation.*;
import play.templates.*;
import play.mvc.Scope.*;
import javax.persistence.*;
import play.Logger;
import play.templates.JavaExtensions;
#Entity
public class Product extends Model {
#As(lang={"*"}, value={"yyyy-MM-dd hh:mm:ss"})
public Date creationDate;
}
Your controller:
package controllers;
import play.*;
import play.mvc.*;
import java.util.*;
import models.*;
public class Products extends CRUD {
}

I finally found in the documentation my answer:
You can indeed customize each field; a more extensive example can be found on the lunatech blog using jquery datatables which also shows how to modify pagination.
#{crud.table fields:['name', 'company']}
#{crud.custom 'company'}
<a href="#{Companies.show(object.company.id)}">
${object.company.name}
</a>
#{/crud.custom}
#{/crud.table}
PS.
#AditSaxena hint was good and indeed a simple solution; but not what I wanted because it's not acceptable that the 'hint' is not correct! Clearly confusing for a user!
So for a datetime input (the specific question) we can combine the annotation (described in the doc)
#As(lang={"*"}, value={"yyyy-MM-dd hh:mm:ss"})
with a custom hint, eg.
#{crud.custom 'mydate'}
<span class="crudHelp">
Date format: etcetc.
</span>
...
#{/crud.custom}
I'll also point out that you can write your own validator
