我的数据架构有点问题。我正在使用 mongoose 构建一个带有 mongodb 和 node.js 的应用程序，这是我的架构：

var Schema = mongoose.Schema;

var misc = new Schema ({
  publictransp: {type: Number},
  culture: {type: Number},
  traffic: {type: Number},
  nature: {type: Number},
  supermarket: {type: Number},
  school: {type: Number},
  sport: {type: Number},
  nightlife: {type: Number},
  mean: {type: Number}
});

var rue = new Schema ({
  nomrue: {type: String},
});

var Quartiers = new Schema ({
  nomquartier: {type: String},
  listerue: [rue],
  critere: [misc]
})

var location = new Schema ({
  nomville: {type: String, required: true},
  description: {type: String, required: true},
  quartiers: [Quartiers],
  modified: {type: Date, default: Date.now}
});


var ObjModel = mongoose.model('Obj',location);

这是应用程序代码：

//LIST PRODUCTS
app.get('/api/products', function (req, res){
  return ObjModel.find(function (err, products){
    if (!err) {
      return res.send(products);
    } else {
      return console.log(err);
    }
  });
});

//CREATE PRODUCTS
app.post('/api/products', function(req,res){
  var product;
  console.log("POST: ");
  console.log(req.body);
  product = new ObjModel({
    nomville: req.body.nomville,
    description: req.body.description,
    quartiers: [Quartiers],
    critere: [misc],
    rue: [rue]
  });
  product.save(function(err){
    if (!err) {
      return console.log("created");
    } else {
      return console.log(err);
    }
  });
  return res.send(product);
});

//READ SINGLE ELEMENT
app.get('/api/products/:id', function(req,res){
  return ObjModel.findById(req.params.id, function(err, product) {
    if (!err) {
      return res.send(product);
    } else {
      console.log(err);
    }
    return res.send(product);
  });
});

//UPDATE METHOD

app.put('/api/products/:id', function(req,res){
  return ObjModel.findById(req.params.id, function(err, product){
    product.nomville = req.body.nomville;
    product.description = req.body.description;
    product.quartiers= req.body.quartiers;
    return product.save(function(err){
      if (!err) {
        console.log("updated");
      } else {
        console.log(err);
      }
      return res.send(product);
    });
  });
});

//DELETE METHOD

app.delete('/api/products/:id', function(req,res){
  return ObjModel.findById(req.params.id, function(err, product){
    return product.remove(function(err){
      if (!err) {
        console.log("removed");
        return res.send(' ');
      } else {
        console.log(err);
      }
    });
  });
});

我将以下 Jquery 查询发送到数据库：

    jQuery.post("/api/products", {
  "nomville": "Strasbourg",
  "description": "Ville de Strasbourg",
  "quartier": [
    {
      "nomquartier": "Centre",
      "listerue": [
          {
            "nomrue": "22 Novembre"
          },
          {
            "nomrue": "Abattoir"
          },
          {
            "nomrue": "Fonderie"
          },
          {
            "nomrue": "Francs Bourgeois"
          }
      ]
    },
    {
      "nomquartier": "Cité de l'Ill",
      "listerue": [
          {
            "nomrue": "Anguille (chemin de l)"
          },
          {
            "nomrue": "Civelles (promenade des)"
          },
          {
            "nomrue": "Hechner (rue)"
          },
          {
            "nomrue": "Phario (pont)"
          }
      ]
    },
    {
      "nomquartier": "Krutenau",
      "listerue": [
          {
            "nomrue": "Abreuvoir (rue de l)"
          },
          {
            "nomrue": "Bain Finkwiller (rue du)"
          },
          {
            "nomrue": "Fustel de Coulanges (quai)"
          },
          {
           "nomrue": "Hôpital (place de l)"
          }
      ]
    }
  ],
  "critere":[
    {
      "publictransp": 2,
      "culture": 8,
      "traffic": 5,
      "nature": 7,
      "supermarket": 3,
      "school": 5,
      "sport": 6,
      "nightlife": 4,
      "mean": 5
    },
  ]
}, function(data, textStatus, jqXHR) {
    console.log("Post resposne:"); console.dir(data); console.log(textStatus);         console.dir(jqXHR);
});

但是即使终端输出正确，我的输出也不完整，数据库显示以下输出：编辑这就是我使用您的代码 Samy 得到的结果

[
  {
    "nomville": "Strasbourg",
    "description": "Ville de Strasbourg",
    "_id": "526ee45a8d29774913000004",
    "__v": 0,
    "modified": "2013-10-28T22:25:30.970Z",
    "quartiers": []
  }
]

你可以在这里找到我原来的帖子有另一个问题：错误：key $conditionalHandlers must not start with '$' mongodb it has some extra code

我发现了问题：

嵌入式模式必须具有以下形式，例如：

var misc = new Schema ({
   publictransp: Number, 
   culture: Number,
   nature: Number,
   [ etc...]
})

请提供您的 api 视图的代码（/api/products 的视图）。编辑：确定在错误中找到：键 $conditionalHandlers 不能以 '$' mongodb 开头

保存完成后先放res.send，像这样：

app.post('/api/products', function(req, res, next){
  var product;
  console.log("POST: ");
  console.log(req.body);
  product = new ObjModel({
    nomville: req.body.nomville,
    description: req.body.description,
    quartier: req.body.quartier,
    critere: req.body.critere,
    rue: req.body.rue,
  });
  product.save(function(err){
    if (err) return next(err);
    res.send(product);
  });
});

这是什么（因为它无法工作）：

quartiers: [Quartiers],
critere: [misc],
rue: [rue]
