# Payload Relationship ObjectID Plugin This plugin automatically enables all Payload `relationship` and `upload` field types to be stored as `ObjectID`s in MongoDB. Minimum required version of Payload: `1.9.5` ## What it does It injects a `beforeChange` field hook into each `relationship` and `upload` field, which converts string-based IDs to `ObjectID`s immediately prior to storage. #### Usage Simply import and install the plugin to make it work: ```ts import { relationshipsAsObjectID } from '@payloadcms/plugin-relationship-object-ids' import { buildConfig } from 'payload/config' export default buildConfig({ // your config here plugins: [ // Call the plugin within your `plugins` array relationshipsAsObjectID() ] }) ``` ### Migration Note - this plugin will only store newly created or resaved documents' relations as `ObjectID`s. It will not modify any of your existing data. If you'd like to convert existing data into an `ObjectID` format, you should write a migration script to loop over all documents in your database and then simply resave each one. ### Support If you need help with this plugin, [join our Discord](https://t.co/30APlsQUPB) and we'd be happy to give you a hand.
