Query by array using NextJs
I have a collection “notification” with an array field “readers” that contains user IDs of any user that reader’s the notification.
I want to query by listing all notifications that does not contain the current logged in user ID if that user ID exist in the readers.
Any help or suggestions?
TL;DR
Developers want to query a collection based on an array field and exclude notifications that contain the current user's ID in the readers array. Try this MongoDB query: `{ readers: { $nin: ["current_user_id"] } }` to filter out notifications with the current user's ID.
