Question

ERROR: ErrorException in 814a6fb85b2cceb262c3a8191c08e42742940fc7.php line 223: Trying to get property of non-object (View: /var/www/html/m/TS/resources/views/d/show-details.blade.php)

Actually I am trying to get the username who has stored the result in the database ie TN has got user_id as a foreign key in the table so I need to get the username from that user_id using models but I am getting this problem Trying to get property of non-object when I try to get the username` associated with the id. I dont know where I am doing it wrong.

THE ERROR I AM GETTING IS HERE value="{{$tn->users->username}}" WHICH SHOWS IN THE CACHED FILE.

I have given my code below too to look.

Thank you in advance

Controller

public function details($id) {

        $d= $this->detail->showDetails($id);
        $tn= TN::find($id);

// calling functions from Model
        $n = $d->tN;
        $o = $d->tO;

return view('details.show-details', compact('d','o', 'n', 'tn'));

}

View

foreach($n as $n)
<input style="font-size:10px;font-weight: bold; color:black; background:#59d864;" value="{{$tn->users->username}}" readonly>

Hello I have sorted this problem but forgot to post it in here the problem was here

public function users() {
    return $this->belongsTo(User::class);
}

This should be public function user() rather than users . Because it belongsTo to User class, it should be singular not plural and for hasMany we use plurals. Thank you for your help though ... :)
