node.js - MongoError : Invalid Operation, 没有批量插入操作

Question

下面是我的批量插入代码。

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var UserSchema = new Schema({
    "xyz": String
}, {
    collection: 'user'
});

Api.prototype.Users = mongoose.model('Users', UserSchema);

resultData = [{
    "xyz": "abc"
}, {
    "xyz": "44545"
}, {
    "xyz": "545"
}]

Api.prototype.Users.collection.insert(resultData, function(err, data) {
    if(err) {
        console.log(err);
    } else {
        console.log("User inserted : " + data.result.n);
    }
});

但是我收到这个错误:MongoError: Invalid Operation, No operations in bulk

MongoError: Invalid Operation, No operations in bulk at Function.MongoError.create (/myapp/node_modules/mongoose/node_modules/mongodb/node_modules/mongodb-core/lib/error.js:31:11) at toError (/myapp/node_modules/mongoose/node_modules/mongodb/lib/utils.js:114:22)

我在尝试使用 insertMany 批量插入一个空数组时遇到了这个错误。在尝试批量插入之前，您应该检查是否存在空数组。

if (resultData.length > 0) {
  // do bulk insert...
}
