Laravel – how to redirect Integrity constraint violation: 1451 to failed notifications?

I have a table named merks and it’s id is a foreign key in another table named barangs.
so when I tried to delete a data in table merks but the data have been used in table barangs, it give me this

SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (inventorylite.barangs, CONSTRAINT barangs_merk_id_foreign FOREIGN KEY (merk_id) REFERENCES merks (id))

but I want to give user a notifications like,

"Cant delete this item because its already used"

and redirect them into index view,

this is my destroy controller

public function destroy($id)
    {
        $delete = Merk::destroy($id);
        if($delete){
            return redirect()->route('merk.index')->with('success', 'Merk barang berhasil dihapus');
        }else{
            return redirect()->route('merk.index')->with('failed', 'Merk barang gagal dihapus');
        }
    }

but it’s not working, is there any solutions for this?
thanks in advance..

>Solution :

Use try and catch for it. Example code is here

public function destroy($id)
{
try {
    $delete = Merk::destroy($id);
}
catch (Exception $ex) {
return redirect()->route('merk.index')->with('failed', 'Merk barang gagal dihapus');
}
return redirect()->route('merk.index')->with('success', 'Merk barang berhasil dihapus');
  
}
