When I create a new document with the aforementioned schema the date that is placed in the database is always the same and corresponds to the start time of the current process. It feels like when indexed the now function is called when the schema is created and reused for every newly created documents.

Mongoose date now

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:. Date casting has a couple small cases where it differs from JavaScript's native date parsing. First, Mongoose looks for a valueOf function on the given object, and calls valueOf before casting the date. This means Mongoose can cast moment objects to dates automatically. By default, if you pass a numeric string to the Date constructor, JavaScript will attempt to convert it to a year. 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. MongoDB stores dates as bit integers , which means that Mongoose does not store timezone information by default. Working With Dates.

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.

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.

Disabling timestamps also lets you set timestamps yourself. By default, if you pass a numeric string to the Date constructor, JavaScript will attempt to convert it to a year. For the purposes of these docs, we'll always refer to createdAt and updatedAt. So, for example, if you want to only set updatedAt if a new document is created, you can disable the updatedAt timestamp and set it yourself as shown below:. Notifications Fork 3.
