routes.web
Route::get('/', function () {
return view('dashboard');
});
Route::resource('/departemen',\App\Http\Controllers\DepartemenController::class);
Route::resource('/pegawai',\App\Http\Controllers\PegawaiController::class);
so i tried the Hapus and Edit button. it returning id_departemen instead id from table pegawai. i assume this is because im using join. i use join because i want to show nama_departemen from table departemen in pegawai. so what should i do to fix this.

Answer 1

maybe table departemen should look like this
'id', 'nama_departemen', 'nama_manager', 'jumlah_pegawai'
and table pegawai should look like this :
'id','nomor_induk_pegawai', 'nama_pegawai', 'id_departemen', 'email', 'telepon', 'gender', 'status'
and the controller should look like this :
Pegawai::select ('pegawai.nomor_induk_pegawai','pegawai.nama_pegawai','departemen.nama_departemen','pegawai.email','pegawai.telepon','pegawai.gender','pegawai.status','pegawai.id as id_pegawai','departemen.id as id_departemen')->Join('departemens','pegawais.id_departemen','=','departemens.id')->paginate(5);
just choose which do you want to use, id_pegawai or id_departemen
you can change the join with leftjoin if you need
read this documention for another resolved

Answer 2

The issue here is that your are joining two tables that both have an ID column.
To get around this you need to be specific in what columns you want to return.
For example;
$pegawai = Pegawai::Join('departemens','pegawais.id_departemen','=','departemens.id')->select('pegawais.id','departemens.otherColumnName')->paginate(5);
Hope that helps.
