【问题描述】:
我对 mongoose 还很陌生,我正在尝试编写一个查询,它只在我的主文档中返回一个子文档。
我的文档结构是这样的:
PROFILE
- CONTACTS [ARRAY]
我编写了以下端点来返回一个联系人,其中我传递了个人资料 ID 和子文档的 ID:
"/:owerId/getcontact/:contactId"
我的 Express 函数代码如下所示:
router.route('/:ownerId/getcontact/:contactId')
.get(function(req, res){
Profile.findOne({'owner_id':req.params.ownerId}).then(function(err, profile){
if(err)
res.send(err);
profile.findOne({'_id':req.params.contactId}).then(function(err, contact){
if(err)
res.send(err);
res.json(contact);
})
})
})
但此代码会返回整个配置文件。
当我尝试通过 ID 获取时,它会做同样的事情。这是我的代码,下面是返回的整个配置文件:
router.route('/:ownerId/getcontact/:contactId')
.get(function(req, res){
Profile.findById(req.params.ownerId).then(function(err, profile){
if(err)
res.send(err);
var data = profile.contacts.id(req.params.contactId);
res.json(data);
})
})
