Mongoose plugin that automatically adds createdAt and updatedAt date properties
npm install timestamp-mongooseMongoose Timestamps Plugin
==========================
Simple plugin for Mongoose which adds createdAt and updatedAt date attributes
that get auto-assigned to the most recent create/update timestamp.
npm install timestamp-mongoose
``javascript`
var timestamps = require('timestamp-mongoose');
var UserSchema = new Schema({
username: String
});
UserSchema.plugin(timestamps);
mongoose.model('User', UserSchema);
var User = mongoose.model('User', UserSchema)
The User model will now have and updatedAt properties, which get
automatically generated and updated when you save your document.
`javascript`
var user = new User({username: 'Prince'});
user.save(function (err) {
console.log(user.createdAt); // Should be approximately now
console.log(user.createdAt === user.updatedAt); // true
// Wait 1 second and then update the user
setTimeout( function () {
user.username = 'Symbol';
user.save( function (err) {
console.log(user.updatedAt); // Should be approximately createdAt + 1 second
console.log(user.createdAt < user.updatedAt); // true
});
}, 1000);
});
#### findOneAndModify (mongoose >= 4.0.1)
Mongoose 4.0.1 added support for findOneAndModify hooks. You must the mongoose promise exec for the hooks to work as mongoose uses mquery when a callback is passed and the hook system is bypassed.
`javascript`
User.findOneAndUpdate({username: 'Prince'}, { password: 'goatcheese' }, { new: true, upsert: true })
.exec(function (err, updated) {
console.log(user.updatedAt); // Should be approximately createdAt + 1 second
console.log(user.createdAt < user.updatedAt); // true
});
You can specify custom property names by passing them in as options like this:
`javascript`
mongoose.plugin(timestamps, {
createdAt: 'createdAt',
updatedAt: 'updatedAt'
});
Any model's updatedAt attribute can be updated to the current time using touch()`.
