我有一个 Laravel 5.8 项目，我想将 Ajax 用于我的 CRUD，当然我使用数据表。它工作正常，我成功地将数据保存在数据库中，但有两个问题。我先给你看一下代码。
这是我的Controller：
<?php
namespace App\Http\Controllers\Admin;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Restaurant;
use App\Kitchen;
use Validator;
class RestaurantsController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
if(request()->ajax())
{
return datatables()->of(Restaurant::latest()->get())
->addColumn('action', function($data){
$button = '<button type="button" name="edit" id="'.$data->id.'" class="edit btn btn-primary btn-sm">Edit</button>';
$button .= ' ';
$button .= '<button type="button" name="delete" id="'.$data->id.'" class="delete btn btn-danger btn-sm">Delete</button>';
return $button;
})
->rawColumns(['action'])
->make(true);
}
return view('admin.restaurants.index');
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$rules = array(
'naziv' => 'required|unique:restaurants|max:90',
'adresa' => 'required|max:150',
/*
'pon_pet' => 'required',
'min_dostava' => 'required|numeric|max:5',
'vrijeme_dostave' => 'required|max:10|numeric',
'cijena_dostave' => 'required|numeric|max:5',
'podrucije_grada' => 'required',
'br_telefona' => 'required|numeric|unique:restaurants',
'lokacija' => 'max:999',
'kuhinja_id' => 'required',
'user_id' => 'required'
*/
);
$error = Validator::make($request->all(), $rules);
if($error->fails())
{
return response()->json(['errors' => $error->errors()->all()]);
}
$form_data = array(
'naziv' => $request->naziv,
'adresa' => $request->adresa,
/*
'pon_pet' => $request->pon_pet,
'min_dostava' => $request->min_dostava,
'vrijeme_dostave' => $request-> vrijeme_dostave,
'cijena_dostave' => $request->cijena_dostave,
'podrucije_grada' => $request->podrucije_grada,
'br_telefona' => $request->br_telefona,
'lokacija' => $request->lokacija,
'kuhinja_id' => $request->kuhinja_id,
'user_id' => $request->user_id
*/
);
Restaurant::create($form_data);
return response()->json(['success' => 'Data Added successfully.']);
}
}
在我的blade：

问题
第一个问题是，当我单击Add提交输入时，它会保存我的数据，但它仅在白页上显示响应，而不仅仅是将其添加到数据表中。
第二个问题是我的数据甚至没有显示在数据表中。它是空的，我不知道为什么。
请帮忙，我该怎么办？有什么建议么？
