Database Notifications UUIDv7

[bayukartiko]

Does Laravel’s Database Notifications id column only support UUID v4?
Is it possible to enable protected $guarded = ['id']; on a custom Notification model? I’m planning to use PostgreSQL 18’s built-in uuidv7() function.

However, when I try to update the value inside the data column using:

Notification::where('type', 'progress')
    ->first()
    ->update([
        'data->finished_at' => Carbon::now()->toIso8601ZuluString('microsecond')
    ]);

The data field does not get updated.

But when I disable protected $guarded = ['id']; and execute the exact same update, the data does update successfully.

Why is it only possible to update the data when using UUID v4?
I want to use UUID v7 instead.

Laravel’s notification system does not require UUID v4, and UUID v7 works perfectly.
Your issue is caused by guarding the id column (protected $guarded = ['id']), which interferes with updates on a JSON column using the data->key syntax.
It’s not related to the UUID version at all.

fix option 01:

Use $fillable instead of $guarded
protected $fillable = ['data'];

option 02:
Notification::unguarded(function () {
Notification::where('type', 'progress')->first()->update([
'data->finished_at' => now()->toIso8601ZuluString('microsecond'),
]);
});
