貓鼬 - 蒙戈{[CastError：演員到對象失敗值「......」在路徑「...」

Question

我有這樣的錯誤：

{ [ValidationError: Contact validation failed] 
    message: 'Contact validation failed', 
    name: 'ValidationError', 
    errors: 
    { Contact: 
     { [CastError: Cast to Object failed for value "ContactExample" at path "Contact"] 
     message: 'Cast to Object failed for value "ContactExample" at path "Contact"', 
     name: 'CastError', 
     kind: 'Object', 
     value: 'ContactExample', 
     path: 'Contact', 
     reason: undefined }, 
} 
Same for ContactType 

我的代碼如下：

ContactSchema.js：

var mongoose = require('mongoose'); 
var Schema = mongoose.Schema; 

var Contact = new Schema({ 
    Contact: {Type: String}, 
    ContactType: {Type: String}, 
    ContactOwner: {type: String} 

}); 
module.exports = mongoose.model("Contact", Contact); 

路線：

app.post('/newcontact', isLoggedIn, function(req, res) { 
    ContactModel.count({"Contact": req.body.Contact}, function(err, result){ 
     if (result>0) res.send('Contact already taken'); 
     else{ 
      var newContact = new ContactModel(); 
      console.log(req.body); 
      newContact.ContactOwner = req.user.email; 
      newContact.Contact = req.body.Contact; 
      newContact.ContactType = req.body.ContactType; 
      newContact.save(function(err){console.log(err);}); 
      res.send('Done'); 
     } 
    }); 
}); 

我試圖填補該領域「_id」，也做ContactModel（ContactOwner：......），但它仍然給我的錯誤

的type模式中的不正確，請更換模式定義的情況下，

var Contact = new Schema({ 
    Contact: {type: String}, 
    ContactType: {type: String}, 
    ContactOwner: {type: String} 
});
