A helper method for an ampersand-view / ampersand-model to fetch the children if they have a url and fetch method.

Fetch Children

var View = require('ampersand-view'); // you can use ampersand-model/ampersand-state here too
var _ = require('lodash');

module.exports = View.extend({
  fetchChildren: function(options) {
    _.chain(this._children)
      .keys()
      .each(function(key) {
        if(_.isFunction(this[key].url) && _.isFunction(this[key].fetch) {
          this[key].fetch(options);
        }
      }, this);
  }
});
