Question

我有一个计划对象，当我从API收到时，它具有以下结构：

schedule : {
    id,
    name,
    day,
    month,
    year,
    shifts : [
        {
            id, 
            user,
            tasks : [...]
        }
    ]
}

我创建了三个services：Schedule，Shift和Task。例如，我的Schedule服务是

app.factory('Schedule', function()
{
    return function() {
        // my methods here such as:

        this.save = function();
        this.remove = function();
        this.createShift = function();
        this.registerShift = function(shift);
    }
});

我希望这些服务扩展我从API收到的原始对象，以便我的schedule成为：

schedule : {
    id,
    name,
    day,
    month,
    year,
    shifts,
    this.save = function(),
    this.remove = function(),
    this.createShift = function(),
    this.registerShift = function(shift)
}

现在，我能想到的唯一方法是

angular.extend(scope.schedule, new Schedule());

但是，如果我可以将schedule传递给我的服务并将其分配回来并保留所有原始对象，那就更好了，例如：

scope.schedule = new Schedule(scope.schedule);
// And all the attributes such as name, id, day, month, year are also returned back

这可能吗？

Answer 1

function Ctrl($scope,Shedule){
  $scope.schedule = {
    id,
    name,
    day,
    month,
    year,
    shifts : [
        {
            id, 
            user,
            tasks : []
        }
    ]
 };
// pass schedule object as a parameter
Shedule.processShedule.call($scope.schedule);
}

service:

app.service('Shedule',function()
{
    this.processShedule=function(obj){
         //you can access your parent object using self variable
         var self=obj;
         self.name="xyz";
         self.year="2014";
    }
}

这可能不是最好的方法，但我最终使用了以下（使用下划线）：

app.factory('Schedule', function()
{
    return function(schedule) {
        // This adds all the key => value pairs to 'this'
        var self = this;
        _.each(schedule, function(value, key)
        {
           self[key] = value;
        }); 

        this.save = function();
        this.remove = function();
        this.createShift = function();
        this.registerShift = function(shift);
    }
});

然后在我的指示中，我去了

scope.schedule = new Schedule(scope.schedule);
