I'm trying to insert a document using this query:
db.collection.insert(
{
date: Date('Dec 12, 2014 14:12:00')
})
Unfortunately, I keep getting an error.
Can someone please help me figure out how to successfully insert a date into my collection without encountering any errors?
It seems like you may be encountering a different issue because the code provided above will give you the current date in string format, regardless of any arguments passed to it. According to the official documentation: JavaScript Date objects can only be created using the JavaScript Date method as a constructor. Using it as a regular function (without the new operator) will return a string instead of a Date object. Unlike other JavaScript objects, Date objects do not have a literal syntax.
To ensure you get the correct date, consider using the following code snippet and remember that JavaScript's Date constructor uses a 0-based index for the month parameter:
var myDate = new Date(2014, 11, 12, 14, 12);
db.collection.insert({ "date": myDate });
Dealing with JavaScript date objects can be quite perplexing at times. Depending on how you input the arguments to create them, the outcomes vary.
For instance, some may advise you to attempt the following:
var myDate = new Date(2014, 11, 12, 14, 12)
While this seems okay, there is a catch.
It's worth noting that when instantiating a Date object in JavaScript, certain methods utilize the "local" timezone for date creation, while others adhere to the UTC or "universal" time zone as a standard. This aligns with what MongoDB requires and is commonly regarded as the best approach for storing dates within your application. Any conversions should be handled in your code rather than in the data store itself. This practice allows you to seamlessly manage multiple locales without complications.
Therefore, the recommended way to go about it is:
var date = new Date("2014-12-11T14:12:00Z")
Additionally, there exists a convenient feature in the MongoDB shell which achieves similar results but is tailored to the syntax:
var date = new ISODate("2014-12-11T14:12:00Z")
By doing this, you obtain a UTC Date value that behaves as anticipated when stored. It's advisable to always work with UTC when dealing with dates in MongoDB.
