Play Framework CRUD

Question

I wanted to develop a RESTful Application with use of CRUD in Play framework. Unfortunately I can't find a way to define DELETE and PUT in the routes of Play. Maybe there is just POST and GET available in Play?

Answer 1

Are you sure you cannot use DELETE/PUT? The docs say otherwise.

The HTTP method

The HTTP method can be any of the valid methods supported by HTTP (GET, POST, PUT, DELETE, HEAD).

Play 2.x has not a CRUD module known from 1.x branch (IMHO fortunately), for defining routes using not standard methods like DELETE or PUT you need to just use required method in the route:

conf/routes:

PUT     /put-item     controllers.Application.putItem()

Anyway to use them from the browser methods other than GET or POST you'll need to create an AJAX call, There is a large step-by-step sample on this topic, anyway you can also build it with common jQuery.ajax() by defining the request type

$.ajax({
  type: "PUT",
  url: "@routes.Application.putItem()",
  data: { name: "John", location: "Boston" }
}).done(function( msg ) {
  alert( "Data Saved: " + msg );
});

A good way to define these is using a wildcard (*) This will allow you to use any method valid http method, including those that you have asked about.

For example,

*  /items/{id}               Items.display

in routes will allow a GET /items/15 or a PUT /items/15. Use wildcards like this to make your route definitions simpler and more flexible.
