Listen to relationship events

There is a package that adds relationship events, see this blog post.

https://laravel-news.com/relationship-events

Should work with nova as it's independent to laravel event system but I haven't tried

Thanks, I hadn't heard of that package. Unfortunately I've tried it and it doesn't work with Nova. I know the package is working by using tinker, but the events aren't triggered by Nova.

@unlikenesses - I dont think this package has anything to do with tinker. It simply adds additional model events for relationships to the core events.

Did this work for you in a non-nova environment?

Say you have a User and Comment with a hasMany relationship (one user has many comments) and belongsTo inverse (A comment belongs to a User) you should be able to add this to your User model

protected static function boot()
    {
        parent::boot();

        static::belongsToAssociated(function ($relation, $related, $parent) {
            Log::info("User has been associated with comment {$parent->id}.");
        });
    }

When you add a new Comment you should see an entry in your logs. If this works without Nova then I would try seeing if when you add a comment in Nova admin panel you see another log message

I meant that I used tinker to check that the events were firing. And they were. So yes it did work for me in a non-nova environment.

I added logging to the listeners, and they are triggered in a non-nova environment (tinker), but they are not triggered in Nova.

@unlikenesses - Im not used to Nova but the doucumentation at https://nova.laravel.com/docs/1.0/resources/#resource-events

Shows you might need to use a Model Observer and register with Nova for this to work. It might work out the box with a model Observer in you model, if you have just used the boot() method above

If not then I'm out of ideas I'm afraid
