使用angularjs發佈從express節點到mongodb的數據

Question

您好我正在構建一個應用程序，使用平均堆棧，並使用角度控制器成功加載初始數據。但是，當添加用戶時，它會嘗試將用戶對象發佈到服務器端，但是「/ api/contacts」返回錯誤500,（TypeError：undefined不是函數）。代碼如下：

var Contact = mongoose.model("Contact", schema.contactSchema, "contactlist"); 

    module.exports = { 

     getcontactlist : function (request, response) { 

      Contact.find({ }, function (err, docs) { 
       response.send(docs); 
      }); 

     }, 

     postcontactlist : function(request, response){ 

    console.log("request: " + request.body); 

    Contact.insert({ "name" : "Vincent Moyet", "email" : "vincentmoyet@gmail.com", "number" : "0987654321" }, function(err, docs){ 

     if(err){ 

      var errorMsg = "error: " + err.message; 
      console.log(errorMsg); 
      response.status(500).send(err); 

     } else { 
      console.log("success"); 
      response.status(200).end(); 
     } 
    }); 
} 

    }; 

有人可以開導哪裏im出錯了？

Answer 1

[我張貼另一個答案的問題，筆者改寫他們的問題 - @learningAngularIsFrustrating：你應該寫了一個新問題而不是做你的原來的這麼大的編輯]

第2行的代碼是什麼「（（/Users/Sites/express/api/contacts.js:22:11）？我想這是insert和認爲你可能會更好與save（這就是我用在你的類似情況）

var contact = new Contact({ "name" : "Vincent Moyet", "email" : "vincentmoyet@gmail.com", "number" : "0987654321" }) 
contact.save(function(err, docs){...});

看起來你沒有報告成功返回給客戶端

postcontactlist : function(request, response){ 

     Contact.insert(request.body, function(err, docs){ 
        if(err){ 
         console.log("error: " + err.message); 
       ---> response.status(500).send(err) 
        } else { 
         console.log("success"); 
       ---> response.status(200).end() 
        } 
     }); 

    }
