Instead of accessing models collection directly from within views, use get(), at() or underscore functions. If you are looking for length of the collection, use this.length instead. If you want to modify collection use this.add, this.remove, this.push and this.pop methods instead.
The following patterns are considered warnings:
Backbone.Collection.extend({
initialize: function() {
_.first(this.models);
}
});The following patterns are not warnings:
Backbone.Collection.extend({
initialize: function() {
this.at(0);
}
});
