将对象插入嵌入式对象

Question

我正在尝试将新对象添加到嵌入式对象中，我看到请求已正确发送（POST 200 OK），但最终未创建对象

这是我拥有的mongodb结构

    {
    "data": {
        "practices": [
            {
                "_id": "5d3477b38f0bc920ce6b6fe0",
                "name": "some name",
                "createdBy": "John",
                "description": "desc",
                "methodologies": [
                    "method 1"
                ],
                "standards": [
                    {
                        "requirementId": "123",
                        "standardId": 333,
                        "assignedBy": "Mike",
                        "scores": null
                    }
                ],
                "updated_date": "2019-08-22T05:59:29.975Z"
            }
        ]
    }
}

我想添加分数对象：

{
        createdBy: {
            type: GraphQLString
        },
        score: {
            type: GraphQLBoolean
        },
        comment: {
            type: GraphQLString
        }
    }

这是突变部分：

addScoreToPracticeInStandard: {
                type: practiceType,
                args: {
                    id: {
                        name: 'id',
                        type: new GraphQLNonNull(GraphQLString)
                    },
                    standards: {
                        type: GraphQLList(assignedToPracticeRequirementInputType)
                    },
                    scores: {
                        type: new GraphQLList(assignedToPracticeScoreInputType)
                    },
                    requirementId: {
                        type: GraphQLNonNull(GraphQLString)
                    },
                    createdBy: {
                        type: GraphQLNonNull(GraphQLString)
                    },
                    score: {
                        type: GraphQLNonNull(GraphQLBoolean)
                    },
                    comment: {
                        type: GraphQLNonNull(GraphQLString)
                    }
                },

                resolve(root, params) {
                    return PracticeModel.update({
                            "id": params.id,
                            "standards.requirementId": params.requirementId
                        },
                        {
                            $push: {
                                "standards.$.scores": {
                                    "createdBy": params.createdBy,
                                    "score": params.score,
                                    "comment": params.comment
                                }
                            }
                        },
                        function (err) {
                            if (err) return next(err);
                        }
                    );

发送后

    mutation {
  addScoreToPracticeInStandard(id: "5d3477b38f0bc920ce6b6fe0",requirementId: "123", standards: [], scores: [], createdBy: "Janko", score: true, comment: "komentarz sierpiowy")
  {
        _id
        name
        createdBy
        description
        methodologies
        standards
        {
            requirementId
            standardId
            scores{
                createdBy
                score
                comment
            }
        }
        updated_date
    }
}

我看到的回应

    {
    "data": {
        "addScoreToPracticeInStandard": {
            "_id": null,
            "name": null,
            "createdBy": null,
            "description": null,
            "methodologies": null,
            "standards": null,
            "updated_date": null
        }
    }
}

任何想法，我在做什么错了？

最后，我如下解决了该问题：

resolve(root, params) {
                    return PracticeModel.findById(params.id).exec()
                        .then(PracticeModel.update({standards: {$elemMatch: {"requirementId": params.requirementId}}},
                            {
                                $addToSet: {
                                    "standards.$.scores":
                                        {
                                            createdBy: params.createdBy,
                                            score: params.score,
                                            comment: params.comment
                                        }
                                },
                                $set: {updated_date: new Date()},
                            }
                            ,
                            function (err) {
                                if (err) return next(err);
                            })
                        );
                }
            },
