使用角带选择多个和猫鼬插入多个值

Question

我正在尝试使用 mongoose db 和角带选择多个执行多个插入。问题是每次我插入位置时，我在 mongodb 中得到的都是“位置”：[ {“名称”：“[object Object]，[object Object]”，“_id”：ObjectId（“54b1bbdabbc1a9c603c4c1e2”）}] 这个是我的架构

var userSchema = new mongoose.Schema({
username: { type: String, lowercase: true, unique: true },
email: { type: String, lowercase: true, unique: true },
profile: {
    name: String,
    gender: String,
    locations: [{
        name: String
    }],
    created_at: Date,
    updated_at: { type: Date, default: Date.now },
},
});

路线

app.post('/api/users/profile/:username', function(req, res, next) {
if (req.params.username) {
    User.findOne({ username: req.params.username }, function(err, user) {
        if (err) return next(err);
        user.profile.name = req.body.name || '';
        user.profile.gender = req.body.gender || '';
        user.profile.locations.push({ name: req.body.location.name });

        user.save(function(err) {
            if (err) return next(err);
            res.send(200);
        });
    });
}else{
    return res.send(400, { message: 'User does not exist!!' });
}
});

HTML

<button type="button" class="btn btn-lg btn-block btn-default" name="location.name" ng-       model="location.name"data-html="1" data-multiple="1" data-animation="am-flip-x" ng-options="country.name for country in countries" bs-select>
Action <span class="caret"></span></button>

角度

angular.module('Chat')
.controller('ProfileCtrl', ['$scope', '$routeParams', 'Profile', function($scope,     $routeParams, Profile) {
    $scope.profile = function() {
        Profile.updateProfile({
            username: $routeParams.username,
            name: $scope.name,
            gender: $scope.gender,
            locations: $scope.location.name
        })
    }

    $scope.countries = [{
        name: 'Nueva York'
    }, {
        name: 'Mozambique'
    }, {
        name: 'Tulua'
    }, {
        name: 'Australia'
    }];
}]);

没关系.. 不需要做 user.profile.locations.push({ name: req.body.location.name });只是 user.profile.locations = req.body.location || [];
