我的控制器中有以下代码，从mongo检索对象并将其发送给客户端：

 index: function(req, res){
    List.find({user:req.session.user.id}).exec(function foundLists(error, foundLists) {
        if(error) {
            return res.json({error:error});
        } else {
            return res.view({ title:'Lists',lists:foundLists });
        }
    });
 }

我认为我会执行以下操作：

extends ../layout
  block content
    .container
        p #{lists}

呈现：[object Object],[object Object]

如果我做 p= JSON.stringify(lists)

它呈现：

[{"user":"546109c0d640523d1b838a32","name":"third","createdAt":"2014-11-11T19:39:36.966Z","updatedAt":"2014-11-11T19:39:36.966Z","id":"546265f83e856b642e3b3fed"},{"user":"546109c0d640523d1b838a32","name":"forth","createdAt":"2014-11-11T19:42:09.268Z","updatedAt":"2014-11-11T19:42:09.268Z","id":"546266913e856b642e3b3fef"}]

我正在努力实现：

#lists
    each list in lists
       p #{list}

但是我得到这个错误： Cannot read property 'length' of undefined

我正在使用Sails和Jade 1.7.0

我创建了一个名为AppService的服务.它的函数getUserPostionOptions应该返回一个对象:

getUserPostionOptions: function (user) {
   // PositionOptions.findOne({id:'53f218deed17760200778cfe'}).exec(function (err, positionOptions) {
        var positionDirectionsOptions = [1,2,3];
        var positionLengthsOptions = [4,5,6];
        var object = {
            directions:positionDirectionsOptions, 
            lengths:positionLengthsOptions
        };   
        return object;
  // });
}

这工作,在我的控制器positionOptions正确填充:

var positionOptions = AppService.getUserPostionOptions(user);

但是,当我取消注释查找查询时,找到该项,但该对象返回undefined.

提前感谢您的帮助
