I am struggling to assign a default value for a field living in my model. As per your doc , i can assign a static value. But assigning a function, which is supported by mongoose , does not seem to work there. My problem: Assigning a function instead of a value in mongoose schema does not assign default value when in the form creation interface. Thanks for your message and welcome to our community! Actually the date in the form is not filled what value could be printed as the record was not created yet! Assigning a function as default in mongoose schema does not work Help me!

Mongoose date now

Mongoose schemas support a timestamps option. If you set timestamps: true , Mongoose will add two properties of type Date to your schema:. Mongoose will then set createdAt when the document is first inserted, and update updatedAt whenever you update the document using save , updateOne , updateMany , findOneAndUpdate , update , replaceOne , or bulkWrite. The createdAt property is immutable, and Mongoose overwrites any user-specified updates to updatedAt by default. For the purposes of these docs, we'll always refer to createdAt and updatedAt. But you can overwrite these property names as shown below. Set timestamps: false to skip setting timestamps for that particular operation. You can also set the timestamps option to an object to configure createdAt and updatedAt separately. For example, in the below code, Mongoose sets createdAt on save but skips updatedAt. Disabling timestamps also lets you set timestamps yourself. For example, suppose you need to correct a document's createdAt or updatedAt property. You can do that by setting timestamps: false and setting createdAt yourself as shown below. Mongoose also supports setting timestamps on subdocuments. Keep in mind that createdAt and updatedAt for subdocuments represent when the subdocument was created or updated, not the top level document.

Is it working on your side as well? This means Mongoose can cast moment objects to dates automatically. Already have an account?

When you create a user document , Mongoose will cast the value to a native JavaScript date using the Date constructor. An invalid date will lead to a CastError when you validate the document. Dates have two built-in validators: min and max. These validators will report a ValidatorError if the given date is strictly less than min or strictly greater than max. MongoDB supports querying by date ranges and sorting by dates. Here's some examples of querying by dates, date ranges, and sorting by date:.

Returns a date either as a string or as a Date object. The date can contain a date and a time, known as a datetime. The UTC datetime stores an unsigned bit integer value, indicating the number of milliseconds after the Unix epoch January 1st, at UTC. You can use Date for deployments hosted in the following environments:. Date returns the current date as a string in mongosh. You can specify a particular date by passing an ISO date string with a year within the inclusive range 0 through to the new Date constructor or the ISODate function. These functions accept the following formats:. Internally, Date objects are stored as a signed bit integer representing the number of milliseconds since the Unix epoch Jan 1, Not all database operations and drivers support the full bit range. You may safely work with dates with years within the inclusive range 0 through

Managing dates and times is an essential aspect of data modeling in any database system. In MongoDB, date formatting and manipulation can be both versatile and complex. From the simplest usage of Date fields to more advanced techniques such as querying and indexing date fields, you will come away with a robust understanding of handling datetime in Mongoose effectively. Mongoose serves as a powerful bridge between MongoDB and the Node. It becomes especially important to consider this behavior when working across different time zones and storing data that needs a standardized format, such as UTC. To maximize the functionality and avoid common pitfalls with Date types in Mongoose, your schemas need to be defined accurately, and operations regarding dates—such as sorting, formatting, and querying—need to be handled with care. However, often applications need to automatically record the creation and modification times of a document. In such cases, Mongoose provides a shortcut:. With the timestamps option enabled, Mongoose automatically adds createdAt and updatedAt fields to your schema, and manages those fields for you.

As brycelund pointed out, the schemaType default property can hold either a value or a function. The text was updated successfully, but these errors were encountered:. It feels like when indexed the now function is called when the schema is created and reused for every newly created documents. Thanks lineus! EDIT: I'm just silly for thinking any library is going to return a Date object instead of a string for something that's going to be sent over the network. If a value is set as the default, ie, the return of new Date or Date. Sign up for free to subscribe to this conversation on GitHub. Already on GitHub? Sorry, something went wrong.

When you create a user document , Mongoose will cast the value to a native JavaScript date using the Date constructor.

With this change, each time you create a new doc, the default function will be called and a new Date will be returned as the default. For the purposes of these docs, we'll always refer to createdAt and updatedAt. Be sure you're not using Date. Sign up for free to subscribe to this conversation on GitHub. If the current behavior is a bug, please provide the steps to reproduce. Mongoose converts numeric strings that contain numbers outside the range of representable dates in JavaScript and converts them to numbers before passing them to the date constructor. Don't use jest.
