How rendering in views by using JSON?

[eson]

Hi,
   How I will render my Json values in views.scala.html in play 2.0.

Application:

public static Result ajaxjson()    {
      String contentType = "text/json";
      response().setContentType(contentType);

\\  if am setting this cotent type (above tow line) means new download window open ajaxjson.json file format
\\  Is it correct to use XXX.scala.html file   using for routes/XXX.json?

      ObjectNode error = Json.newObject();      
      error.put("error", "ERROR");                        \\                
      return ok(ajaxjson.render(error));
}

Routes:

GET    /ajaxjson.json    controllers.Application.ajaxjson()

views:

Ajaxjson.scala.html

@(error:org.codehaus.jackson.node.ObjectNode)
@error

THanks,

Eson.

Have you tried:

String contentType = "text/html";

This will show the json error message as text as part of the view.

You don't need the separate view and also don't need to specify the contentType:

    public static Result ajaxjson()    {

        ObjectNode error = Json.newObject();
        error.put("error", "ERROR");

        return ok(error);
    }

route is ok:
GET    /ajaxjson.json    controllers.Application.ajaxjson()

Hahaha, de facto if it returns some error it should be badRequest, of course from technical point of view it doesn't differ but you can use status code in ajax for an  example to perform other action on errors.

        return badRequest(error);

Hi,

   Thanks lot Nilanjan and Biesior,

   

     I am just done for programmatic convention not according to error rendering (not for HTTP code). Ok I changed Json key value.

    now am received  {"myerror":"OWN ERROR"}  in ajaxjson.json file.

    i want to send this value into Application.readJson() method how i will do..?

But specify. do you want to get it in the view ie. via ajax and then send to other controller also with ajax, or just need to send the json to some method if error occures from ajaxjson() ?
