Marionette.CompositeView, how to pass parameters to Marionette.ItemView

Question

I would like to access the app.vent from Marionette.ItemView.

Maybe an option could be to pass a parameter (app.vent) to Marionette.ItemView fr

Answer 1

Since Marionette v2.0.0, childViewOptions is used instead of itemViewOptions to pass parameters to the child view:

var MyCompositeView = Marionette.CompositeView.extend({
  childView: MyChildView,
  childViewOptions: function(model, index) {
    return {
      vent: this.options.vent
    }
  }
});

var MyChildView = Marionette.ItemView.extend({
  initialize: function(options) {
      // var events = options.vent;
  }
});

new MyCompositeView({ vent: app.vent, collection: myCollection});

But to work with events, lets use Marionette.Radio instead of passing app.vent to the view.
