Backbone.js - passing 2 models to 1 view

Question

I'm trying to pass 2 models to the view, but it seems it is not working. Here is my example: http://jsfiddle.net/kahhor/jp4B6/14/ As you can see second alert is showing undefined...

May be I have wrong approach. What I'm trying to do is: in View1 bind event 'change' to Model1... Than by clicking button in View2, call function in Model1 which changes value, and automatically render View1, since it was binded to change event.

But don't forget that View2 has also its own Model2, which I created outside the view and than passed it like new View2({model:Model2});.

It might looked confusing at first, but I think it is simple thing that backbone can do. I just don't know how to do it :)

Thanks,

Answer 1

you can access custom parameters (options) from

window.PopupView = new PopupView({ model: LeftNotificationM, model2: PopupM});

like this:

window.PopupView = Backbone.View.extend({

    // code left out

    initialize: function () {
        this.model.bind('change:notification_num', this.render);
        alert(this.model);
        // your model2 option:
        alert(this.options.model2);
    },

   // code left out
});

Conclusion: "unrecognized options" of a view can be found in this.options
