at the moment you instanciate a view, you can pass whatever arguments you want. normally you pass the model and the collection to be rendered in the compositeView, but you can pass more data if you need.
var MyCompositeView = Backbone.Mationette.CompositeView.extend({
initialize : function (options){
this.dataValue = options.dataValue1;
this.helperObject = options.helperObject;
this.useValues();
},
useValues: function () {
console.log(this.dataValue);
}
});
var helperObject = {
value3 : "I have a value",
value4 : "I dont!"
}; /// a js object literal
var myModel = new MyModel();
var myCollection = new MyCollection();
var myCompositeView = new MyCompositeView({model:myModel,
collection:myCollection,
helperObject:helperObject,
dataValue1:"Hi there"});
notice that Im passing 4 values in the at the time to intanciate the view, and Im reading just two of them, the model and the collection will be handled by marionette, but the other two you can read them in your initialize function.
hope that helps.
