proper way to send ajax json to play framework

proper way to send ajax json to play framework

I've read a couple of posts here regarding how to do this and I can get it
working only half-way.
This works (sending json object as text):
function go(itemid)
{
apiRoutes.controllers.Application.addItem(itemid).ajax({
data: '{"reqid":0,"iid":2,"description":"adsf"}',
dataType: 'text',
contentType:'application/json',
success: function(reply) {
alert(reply)
}
});
}
This does not (sending object as json):
function go(itemid)
{
apiRoutes.controllers.Application.addItem(itemid).ajax({
data: {"reqid":0,"iid":2,"description":"adsf"},
dataType: 'json',
contentType:'application/json',
success: function(reply) {
alert(reply)
}
});
}
And what I really want to do is something like this (I've already set up
the proper combinators):
function go(itemid)
{
apiRoutes.controllers.Application.addItem(itemid).ajax({
data: @Html(Json.stringify(Json.toJson(item))),
dataType: 'text',
contentType:'application/json',
success: function(reply) {
alert(reply)
}
});
}
My controller looks like this:
def addItem(id: Long) = Action (parse.json) { implicit request =>
Logger.info("add item")
request.body.validate(Item.itemReads).map { item =>
thing.addItem(item)
Ok("Succesfully added item.")
}.recoverTotal{
e => BadRequest("Detected error:"+ JsError.toFlatJson(e))
}
}
In the second case, it never gets to the logging code. Instead it returns
a 400 Bad Request immediately (this is likely something triggered in the
Action (parse.json) bit I think).
I'd rather send the object as json because when I convert to string and
description happens to have an apostrophe in it (') that messes things up.
I could probaby escape the apostrophe, but hoping that I'm missing
something simple about how to do this with an object rather than a string.
Thanks
