Question

我正在尝试通过向嵌套文档添加文档列表来更新嵌套文档。这是我的文件：

{
    "_id": {
        "$oid": "5dd847e92921e045f847e46b"
    },
    "type": "tvshow",
    "name": "The Blacklist",
    "overview": "Raymond \"Red\" Reddington, one of the FBI's most wanted fugitives, surrenders in person at FBI Headquarters in Washington, D.C. He claims that he and the FBI have the same interests: bringing down dangerous criminals and terrorists. In the last two decades, he's made a list of criminals and terrorists that matter the most but the FBI cannot find because it does not know they exist. Reddington calls this \"The Blacklist\". Reddington will co-operate, but insists that he will speak only to Elizabeth Keen, a rookie FBI profiler.",
    "homepage": "",
    "id": null,
    "poster_path": "/bgbQCW4fE9b6wSOSC6Fb4FfVzsW.jpg",
    "release_date": null,
    "makers": [],
    "producers": [],
    "actors": [],
    "genres": [
        80,
        18,
        9648
    ],
    "globalRating": null,
    "ratings": [],
    "seasons": [
        {
            "type": "season",
            "name": "Season 1",
            "overview": "",
            "homepage": "",
            "id": null,
            "poster_path": "/ccrCgW1ukxgwBue9ptkpCEjXE6q.jpg",
            "release_date": null,
            "makers": [],
            "producers": [],
            "actors": [],
            "genres": [],
            "globalRating": null,
            "ratings": [],
            "number": 1,
            "episodes": []
        },
        {
            "type": "season",
            "name": "Season 2",
            "overview": "",
            "homepage": "",
            "id": null,
            "poster_path": "/b7o8AOpZPWJO8nP4SK8RRZ2d0B0.jpg",
            "release_date": null,
            "makers": [],
            "producers": [],
            "actors": [],
            "genres": [],
            "globalRating": null,
            "ratings": [],
            "number": 2,
            "episodes": []
        }]
}

，我想在每个季节的嵌套文档的剧集键中添加一个剧集列表。我尝试了整个赛季的每个新剧集，但只有上个赛季才满。似乎使用addToSet运算符删除了我在前几个季节中添加的前几集：

TVShow.update_one({'_id': self._mongo_id, 'seasons.number': self._number}, {'$addToSet': {'seasons.$.episodes': episode}})

有人对这个问题有想法吗？谢谢您的帮助
