I’m using Ember Data beta 8 with Ember 1.5.1. I have a single model defined (Message):
MessagingApp.Message = DS.Model.extend({
subject: DS.attr("string"),
body: DS.attr("string"),
priority: DS.attr("number"),
fromId: DS.attr("string"),
ringtone: DS.attr("string"),
read: DS.attr("boolean")
});
I have several routes defined, a message list and a route to view a message:
Messaging.Router.map(function() {
this.resource("messages", {
path: "/"
}, function() {
this.route("view", {
path: "/:message_id"
});
});
});
I also have a route MessagesViewRoute defined with the following content:
Messaging.MessagesViewRoute = Ember.Route.extend({
model: function(params) {
var message;
message = this.store.find("message", params.message_id);
if (!message.get("read")) {
message.set("read", true);
message.save();
}
return message;
},
setupController: function(controller, message) {
controller.set("model", message);
}
});
This appears to work fine when I transition to the view route from the index, but if I go straight to the view route I get a blank screen with the following unclear error logged to the console:

The aim is to update the model when you view it in order to mark the message as read. I believe that the view route would be the best place to do this, but I may be missing out on a core convention.
