By default, Mongoose uses new Date() to get the current time. If you want to overwrite the function Mongoose uses to get the current time, you can set the timestamps.currentTime option. Mongoose will call the timestamps.currentTime function whenever it needs to get the current time.const...

Mongoose only emits a 'disconnected' event after a heartbeat has failed, so you may want to decrease this setting to reduce the time between when your server goes down and when Mongoose emits 'disconnected'. We recommend you do not set this setting below 1000, too many heartbeats can lead...
Now, whenever a Person object is constructed, it will default the created field to hold the current date/time and the updated field will be set to the current date/time just prior to being sent to MongoDB for storage. Mongoose calls these “middleware,” because they are in spirit to the...

The full query DSL of Elasticsearch is exposed through the search method. For example, if you wanted to find all people between ages 21 and 30: Person.search({range:{age:{from:21,to:30}}},function(err,people){// all the people who fit the age group are here!}); ...

mongoose是一个Node.js的MongoDB对象建模工具,它提供了一种简单而直接的方式来操作MongoDB数据库。在mongoose中,$gte和$lte是MongoDB的查询操作符,用于比较字段的值是否大于等于($gte)或小于等于($lte)指定的值。 如果在使用mongoose时发现$gte和$lte无法正常工作,可能有以下几个原因: ...
mongoose.connect( mongodb://localhost:27017/test?connectTimeoutMS=1000bufferCommands=false) ; // The above is equivalent to: mongoose.connect( mongodb://localhost:27017/test, { connectTimeoutMS: 1000 // Note that mongoose will **not** pull `bufferCommands` from the query string }); 把...
Sometime it’s a good idea to log on the connection open event: connection.once('open', function () { console.info('connected to database') }); The Mongoose models live in the models folder: var models = require('./models'); This middleware will provide access to two collections with...
