在我的數據庫，我有TESTDATA以下設置：數據庫多層排列，不能推數組第二層
test1 [
[0] { test: Array, comments: Array },
[1] { test: Array, comments: Array }
]
下面是我如何定義userSchema，它含有較多的，但我認爲他們是在這種情況下無關緊要。
var UserSchema = new Schema({
test1: { type: Array, required: false },
test2: { type: Array, required: false },
test3: { type: Array, required: false }
});
下面是將數據保存到數據庫的代碼的一部分。 「newTest1」是一系列評論。我一直在試圖給對象添加評論，但一直無法。我的想法是，我首先添加創建對象的數據（請參閱下面的api.js），然後添加註釋。
沒有顯示錯誤，我試圖進入對象的數組只是沒有添加。在api.js（下面的代碼片段）中，我可以將數組的第一層而不是內部的對象推入。這意味着我無法從數據庫中看到數組，但我不知道這是爲什麼。我想如果我以某種方式可以從數據庫中獲取數組，請添加註釋，然後user.save它會起作用，但我不知道如何做，或者如果這是最好的解決方案。有人可以幫我嗎？
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);
};
創建一個新用戶，當用戶的寄存器：
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 {

}
} 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

嗯，好吧。你將如何添加評論？ – Oscar
