Laravel 5.5重複插入到數據庫提交

Question

誰能幫我...我laravel代碼插入兩次，數據庫，當我點擊提交，其雙數據存儲到數據庫中， 這裏是我的代碼： 控制器

public function store(Request $request) 
{ 
    $this ->validate($request,[ 
     'nim' => 'required|max:8', 
     'nama' => 'required|max:30', 
     'alamat' => 'required|max:100', 
     'jenis_kelamin' => 'required|max:9', 
     'no_tlp' => 'required|regex:/[0-9]{12}/', 
     'tempat' => 'required', 
     'tanggal' => 'required', 
     'id_jurusan' => 'required' 
    ]); 
    $simpan = new Mahasiswa([ 
     'nim' => $request->get('nim'), 
     'nama' => $request->get('nama'), 
     'alamat' => $request->get('alamat'), 
     'jenis_kelamin' => $request->get('jenis_kelamin'), 
     'no_tlp' => $request->get('no_tlp'), 
     'tempat' => $request->get('tempat'), 
     'tanggal' => $request->get('tanggal'), 
     'id_jurusan' => $request->get('id_jurusan') 
    ]); 
    $simpan->save(); 

    if (Mahasiswa::create($request->all())) { 
     $request->session()->flash('status', 'success'); 
     $request->session()->flash('pesan', 'Data Berhasil Disimpan'); 
    }else{ 
     $request->session()->flash('status', 'danger'); 
     $request->session()->flash('pesan', 'Data gagal Disimpan!!'); 
    } 

    return redirect('/Mahasiswa/create'); 
} 

這我的模型代碼：

class Mahasiswa extends Model 
{ 
    protected $fillable = ['nim','nama','alamat','jenis_kelamin','no_tlp','tempat','tanggal','id_jurusan']; 
    protected $table = 'mahasiswa'; 
} 

在此先感謝

你兩次保存數據：

$simpan->save(); 

，然後再：

Mahasiswa::create($request->all()) 

只需卸下$simpan->save();線。
