Add author fields

[cheeZery]

Damit tauchen dann wieder die Autor-Felder im Payload auf.

Nach Release führe ich eine manuelle Migration der alten Infos direkt in mongosh durch:

// Step 1: Find all collections with old-format createdBy/updatedBy
var collectionsWithAuthorFields = db.getCollectionNames().filter(function(c) {
    return db.getCollection(c).findOne({ 
        $or: [
            { 'createdBy.value': { $exists: true }, 'createdBy.relationTo': 'users' },
            { 'updatedBy.value': { $exists: true }, 'updatedBy.relationTo': 'users' }
        ]
    });
});

print("Collections to migrate: " + JSON.stringify(collectionsWithAuthorFields));
print("");

// Step 2: Flatten each collection
collectionsWithAuthorFields.forEach(function(colName) {
    var collection = db.getCollection(colName);
    var docs = collection.find({
        $or: [
            { 'createdBy.value': { $exists: true }, 'createdBy.relationTo': 'users' },
            { 'updatedBy.value': { $exists: true }, 'updatedBy.relationTo': 'users' }
        ]
    }).toArray();
    
    var updated = 0;
    docs.forEach(function(doc) {
        var updateFields = {};
        
        if (doc.createdBy && doc.createdBy.relationTo === 'users' && doc.createdBy.value) {
            updateFields.createdBy = doc.createdBy.value;
        }
        if (doc.updatedBy && doc.updatedBy.relationTo === 'users' && doc.updatedBy.value) {
            updateFields.updatedBy = doc.updatedBy.value;
        }
        
        if (Object.keys(updateFields).length > 0) {
            collection.updateOne({ _id: doc._id }, { $set: updateFields });
            updated++;
        }
    });
    
    print(colName + ": flattened " + updated + " documents");
});

print("");
print("Migration complete.");
