In my database, primary key has string and number likes
ex : BRG2289182

My Controller

public function edit(BarangModel $barang)

 return view('fbarangs.edit',compact('barang'));

My Model

class BarangModel extends Model

 protected $fillable = [
 'barang_kode',
 'barang_nama',
 'barang_jenis',
 'barang_hbeli',
 'barang_hjual',
 'barang_stok',
 ];

 protected $table = 'barangs';
 protected $primaryKey = 'barang_kode';

My routes

Route::resource('barangs','BarangController');

my link

<a class="btn btn-primary" 
 href=" route('barangs.edit',$barang->barang_kode) ">
 <i class="fa fa-pencil"></i> 
</a>

I want to do routing for view, edit, delete. in my database, there is one primary key field that uses a mixture of letters and numbers.
and the problem is when I use it for routing why can't it?
but when I change the primary key data to a number, the result is successful. can anyone help me?

answer :
add this code on my model

public $incrementing = false

based on @Travis Britz comments
I get a solution that I have to add a some line at my model

protected $incrementing = false

on my case i need to change protected to public so the answer is

public $incrementing = false

and this working fine now
