Question

我第一次使用Mongo而且我在创建一个包含数组的文档时遇到了困难。该对象传递给nodejs服务器，如下所示：

{
"customerid":"121212",
"name": "Zero 2679",
"email": "a@a.com",
"address": "bla bla bla",
"tokens":[{"ctoken":"123456"},{"ctoken":"1234567"}]
}

代码执行以下操作：

           var newCustomer = new Customer(
            {
              _id: request.body.customerid,
              name: request.body.name,
              email: request.body.email,
              address: request.body.address,
              tokens:request.body.tokens
             });
            newCustomer.save(function (err) {
              if (err) winston.log('error', err);
              // saved!
            })

架构的配置如下：

var customerSchema = new Schema({

//  index: true => Tells mongo to index this paramater because it is used frequently. It makes querying faster
_id: {type: String, unique: true},  // unique customer ID

name: {type: String, default: '', required: true}, // Customer name

//email: {type: mongoose.SchemaTypes.Email, required: true},
email: {type: String, required: true},

address: { type: String, required: true },

toknes: [{ ctoken :{type: String} }]

}, {collection: 'customers'});

当我去查看MongoDB中的对象时，它看起来像这样：

{
"_id": "121212",
"email": "a@a.com",
"address": "bla bla bla",
"tokens": [],
"name": "Zero 2679",
"__v": 0
}

令牌丢失，并且有一个'_v'值，我甚至没有。

请告知我做错了什么？

Answer 1

您的架构中的

tokens: [{ ctoken : String }]

request.body.tokens必须类似= {ctoken: 'some string'}

       var newCustomer = new Customer(
        {
          _id: request.body.customerid,
          name: request.body.name,
          email: request.body.email,
          address: request.body.address,
          tokens:[request.body.tokens]
         });
        newCustomer.save(function (err) {
          if (err) winston.log('error', err);
          // saved!
        })

如果客户数据库文档包含数据，那么您应该执行push操作

Answer 2

在您的架构中应该是：

tokens: [{ type: String }]

由于ctoken不是数据类型。工作架构如下所示：

var customerSchema = new Schema({
 _id: {type: String, unique: true}, 
 name: {type: String, default: '', required: true},
 email: {type: String, required: true},
 address: { type: String, required: true },
 tokens: [{ type: String }]
}, {collection: 'customers'});

Mongoose - 将带有数组的对象插入到mongo DB中
