Hello Peer;

There are annotations that can be used to mark methods for specific http verbs (@GET, @PUT, @POST, etc) it is combined with the @Path annotation which is passed a value for the path to the method (/TileV2, /TileV2/Delete, etc).  I think it is a way to do route creation without multiple lines of java code, like you showed.

Thanks

Don

Ah, yes. Sorry, I was blind.

I am in development mode right now.  I see the put coming into the server and I can get it to go to the method using the @PUT annotation with the @PATH, but the json never gets put into a key so I can’t get the object to update.

"using the @PUT annotation with the @PATH"? What do you mean by that? Hm, excuse my stupidity...

How do you configure your ERXRouteRequestHandler? Something like in er.rest.example.Application (ERRestRouteExample)? I'm always doing something like:

ERXRouteRequestHandler routeRequestHandler = new ERXRouteRequestHandler(ERXRouteRequestHandler.WO);
routeRequestHandler.addRoute(new ERXRoute(Person.ENTITY_NAME, "/Person/{person:Person}", ERXRoute.Method.Put, PersonController.class, "update"));

regards,
Peer

Hello Don,

are you using an Apache? In my case I had to modify webobjects.conf:

# Specific to Apache 2.4
<Location /cgi-bin/WebObjects/>
    <Limit GET POST PUT OPTIONS >
      Require all granted
    </Limit>
    Require all denied
</Location>

Hello;

I have a ERRest project. Everything seems to be working except for when I update an entity the updateAction never gets called.  I put breakpoints in the source code on createAction, updateAction, indexAction, showAction. The method that gets called for PUT is indexAction.  Am I doing something wrong with the code, I took a look at the example apps in Project Wonder and used them to create my boilerplate.
  
Thanks,

Don


The request from the developer tools in the browser:

How the data is being sent:

$.ajax({
url: '/cgi-bin/WebObjects/xxxxxx.woa/ra/TileV2',
type: ‘PUT',
data: workingObject,
dataType: 'json',
contentType: 'application/json',
success: function (data) {
comp._currentTile = data;
console.log(JSON.stringify(data))
bootbox.alert({
title: "Tile Save",
message: "Tile saved successfully",
centerVertical: true
});
comp.resetDirty();
comp.initialize(window.connectorsjson, window.tilejson);;
},
error: function (data) {
bootbox.alert({
title: "Tile Save",
message: "Saving the tile failed, please try again later",
centerVertical: true
});
}
});
