在我的数据库,我有TESTDATA以下设置:数据库多层排列,不能推数组第二层

test1 [ 

    [0] { test: Array, comments: Array }, 
    [1] { test: Array, comments: Array } 

] 

下面是我如何定义userSchema,它含有较多的,但我认为他们是在这种情况下无关紧要。

var UserSchema = new Schema({ 

    test1: { type: Array, required: false }, 
    test2: { type: Array, required: false }, 
    test3: { type: Array, required: false } 

}); 

下面是将数据保存到数据库的代码的一部分。 “newTest1”是一系列评论。我一直在试图给对象添加评论,但一直无法。我的想法是,我首先添加创建对象的数据(请参阅下面的api.js),然后添加注释。

没有显示错误,我试图进入对象的数组只是没有添加。在api.js(下面的代码片段)中,我可以将数组的第一层而不是内部的对象推入。这意味着我无法从数据库中看到数组,但我不知道这是为什么。我想如果我以某种方式可以从数据库中获取数组,请添加注释,然后user.save它会起作用,但我不知道如何做,或者如果这是最好的解决方案。有人可以帮我吗?

HTML:

<form name="edit.test1" ng-submit="ctrl.updateTest1(newComment1, newComment2, ctrl.artikel)"> 

    <div class="form-group"> 
     <label>Kommentarer:</label> 
     <input class="form-control" type="text" name="test1" placeholder="Comment on first value" ng-model="newComment1" autocomplete="off"> 
     <br> 
     <input class="form-control" type="text" name="test1" placeholder="Comment on second value" ng-model="newComment2" autocomplete="off"> 
    </div> 

     <button type="submit" class="btn btn-primary">Submit</button> 

    </form> 

控制器:

app.updateTest1 = function(newComment1, newComment2, index) { 
      app.errorMsg = false; // Clear any error message 
      app.disabled = true; // Lock form while processing 
      // Check if username submitted is valid 

       var userObject = {}; // Create the user object to pass to function 
       userObject._id = app.currentUser; // Pass current user _id in order to edit 

       userObject.test1 = [$scope.newComment1, $scope.newComment2, index]; // Set the new username provided 

       // Runs function to update the user's username 
       User.editUser(userObject).then(function(data) { 

       // Behöver jag lägga till något här?? 

       }); 
      }; 

Userfactory:

userFactory.editUser = function(id) { 
     return $http.put('/api/edit', id); 
    }; 

创建一个新用户,当用户的寄存器:

router.post('/users', function(req, res) { 
     var user = new User(); // Create new User object 
     user.username = req.body.username; // Save username from request to User object 
     user.password = req.body.password; // Save password from request to User object 
     user.email = req.body.email; // Save email from request to User object 
     user.name = req.body.name; // Save name from request to User object 
     user.temporarytoken = jwt.sign({ username: user.username, email: user.email }, secret, { expiresIn: '24h' }); // Create a token for activating account through e-mail 

     // Check if request is valid and not empty or null 
     if (req.body.username === null || req.body.username === '' || req.body.password === null || req.body.password === '' || req.body.email === null || req.body.email === '' || req.body.name === null || req.body.name === '') { 
      res.json({ success: false, message: 'Ensure username, email, and password were provided' }); 
     } else { 
      // Save new user to database 
      user.save(function(err) { 
       if (err) { 
        // Check if any validation errors exists (from user model) 
        if (err.errors !== null) { 
         if (err.errors.name) { 
          res.json({ success: false, message: err.errors.name.message }); // Display error in validation (name) 
         } else if (err.errors.email) { 
          res.json({ success: false, message: err.errors.email.message }); // Display error in validation (email) 
         } else if (err.errors.username) { 
          res.json({ success: false, message: err.errors.username.message }); // Display error in validation (username) 
         } else if (err.errors.password) { 
          res.json({ success: false, message: err.errors.password.message }); // Display error in validation (password) 
         } else { 
          res.json({ success: false, message: err }); // Display any other errors with validation 
         } 
        } else if (err) { 
         // Check if duplication error exists 
         if (err.code == 11000) { 
          if (err.errmsg[61] == "u") { 
           res.json({ success: false, message: 'That username is already taken' }); // Display error if username already taken 
          } else if (err.errmsg[61] == "e") { 
           res.json({ success: false, message: 'That e-mail is already taken' }); // Display error if e-mail already taken 
          } 
         } else { 
          res.json({ success: false, message: err }); // Display any other error 
         } 
        } 
       } else {

首先,您需要在架构上进行一些调整,以使test1数组包含属性为answerscomments的对象,并将它们设置为数组。然后将其插入到你的主架构是这样的:

var nestedSchema = new Schema ({ 
    answers: {type: Array, required: false}, 
    comments: {type: Array, required: false} 
}) 

var UserSchema = new Schema({ 
    test1: { type: [nestedSchema], required: false }, 
    test2: { type: Array, required: false }, 
    test3: { type: Array, required: false } 
}); 

然后user.test1[0].comments.push(newTest1)应能正常工作。推送新评论时,不要忘记通过所需答案的索引。像这样user.test1[index].comments.push(newTest1)

JavaScript数组总是编号为索引,并且不支持命名的索引。除非我遗漏了某些东西,否则它看起来像是在试图通过给它一个不起作用的命名索引来创建一个关联数组。

嗯,好吧。你将如何添加评论? – Oscar
