Node.js 续集查询多对多关系和访问对象

我有一个例子，我从两个表中查询信息，这两个表与一个“直通”表有多对多关系。当我进行查询时，通过不使用“through”表作为表联接引用并接收具有两个表属性的输出记录，似乎我正在正确地进行查询，但我无法访问联接表的字段属性。这是输出的值

{"fullNameSlug":"Tester Test","email":"test@test.com","firstName":"Tester","lastName":"Test","teams":[{"teamName":"Sales","member":{"memberId":1,"memberEmail":"test@test.com","organizationId":1,"teamId":1,"userId":1,"created_at":"2016-08-21T21:15:19.000Z","updated_at":"2016-08-21T22:00:32.000Z","organization_id":1,"team_id":1,"user_id":1}}]}

以下是我的查询以及如何设置数据：

.get(function(req, res){
 models.User.find({
                where: {
                    organizationId: organization.organizationId
                }, attributes: ['email', 'firstName', 'lastName'],
                include: [{ 
                    model: models.Team,
                    attributes: ['teamName']
                }]
            });
        }).then(function(currentUsers){
            res.jsonp(currentUsers);
console.log(currentUsers);
        });

以下是我试图在视图中访问团队名称的方式：

{{currentUsers.teams.teamName}

，它不返回值，但

{{currentUsers.email}

返回正确的用户电子邮件

考虑您的关系，用户通过表成员拥有许多团队，而您的查询将按预期向用户返回许多团队（团队对象数组）。您应该使用

user.teams[0].teamName

按键获取特定的团队，或循环此数组中的对象
