Question

I’ve been following a spine in javascript sample code that that I’ve found. It appears that the sample and the current version of spine differ a bit, since I’ve got almost exactly the same code. The uptick is one of my calls is not getting proxed.

exports.UrlsList = Spine.Controller.create({
  elements: {
      ".items": "items",
      "form": "form",
      "input": "input"
  },
  events: {
    "submit form": "create"
  },

  proxied: ["render", "addAll", "addOne"],

  init: function(){
    Url.bind("create",  this.addOne);
    Url.bind("refresh", this.addAll);
  },

  addOne: function(url){
    var view = Urls.init({item: url});  // The is another controller
    this.items.append(view.render().el); //This is where the error occurs
  },

  addAll: function(){
    Url.each(this.addOne);
  },

  create: function(e){
    e.preventDefault();
    var value = this.input.val();

    if (value) {
      Url.create({content: value});
    }

    this.input.val("");
    this.input.focus();
  }
});

When the addOne function gets called it’s called in the context of a Url, not in of the current class. It appears to not be proxying anything, even though addOne is in the proxy list. Any ideas?

Spine moved away from the proxied array usage recently.

Instead, you should be able to remove the array and use the proxy function:

init: function(){
    Url.bind("create", this.proxy(this.addOne));
    Url.bind("refresh", this.proxy(this.addAll));
},

addAll: function(){
    Url.each(this.proxy(this.addOne));
},
