REST API: create relationship during POST ?

I was wondering if it is possible to create relationship documents via a single CRUD create operation?



Like, I have Documents and Sources Collections. DocumentCollectionType has a "relationship" field to 1 source.



POST /api/documents { title: "Doc title", source: { organisation: "Foobar", url: "..." } }

==> should create a "document" item in the documents collection AND a "source" item in the sources collection in one POST request



Right now, the only way I see is creating the source first, and then reference that one by id when creating the Document.

    would recommend to use Collection:beforeChange Hooks:

    https://payloadcms.com/docs/hooks/collections#beforechange


    const beforeChangeHook: CollectionBeforeChangeHook = async({ req, doc, operation }) => {
      if (operation !== 'create') return doc;
    
      const source = await req.payload.create({
        collection: 'sources',
        data: {}
      });
    
      doc.source = source.id;
      return doc;
    }

    great tip, thanks. Not exactly what I was trying to do (I wanted the logic to live outside of Payload), but I will consider this approach.
