我是相当新的猫鼬,我想写一个查询,只是返回我的主文档中的一个子文档。查询显示子文档不工作
我的文档结构是这样的:
PROFILE
- CONTACTS [ARRAY]
我已经写了下面的终点返回一个触点,在那里我通过配置文件ID和子文档的ID:
“/: owerId/getcontact /:使用ContactID”
我的快递功能的代码如下所示:
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);
})
})
})
但是这个代码返回整个配置文件。
当我尝试通过ID获取它做同样的事情。这里是我的代码,只是下面是返回的整个轮廓:
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);
})
})

谢谢,dNitro,但我得到了相同的结果。看到我的更新... – cnak2
这是因为你的个人资料'_id'与'owner_id'不同,所以你不应该使用'findById'你应该使用'findOne'。答案已更新。 – dNitro
我更改了ownerId参数以包含_id。我只是没有改变param的名字。所以它实际上是通过_id查找配置文件。我试过findOne和findById,出于某种原因,我仍然把整个记录取回来,而不仅仅是子文档。奇怪。 – cnak2
