<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

        return new Proposal([
            'title' => $newTitle,

            'user_id' => $this->user_id,
            'summary' => $this->summary,
            // ...
        ]);
    }
}

@adamwathan I do the same thing in my apps as you're showing here. I really like how simple it is.

Thanks for sharing. 🌮

Why not using eloquent's replicate function?

Why do you need the tap call here? The duplicateAs method returns a new Proposal object and you just call save on it. What am I not seeing?

Do you use request() in your own apps like that or prefer the dependency injection way? (not trolling, just curious)
