透過–resource, 你可以使用這個方法resource()產生以上所有的路由，而不需要一一個別地指定以上的路由。
Actually, by adding the following code line, we have registered the multiple routes for our app. We can check it using the following command.
實際上，藉由加入該程式碼，我們已經為我們的應用註冊了多個路由，我們可使用底下的命令來檢視這些路由：
// CoronaController.php
public function update(Request $request, $id)
{
$validatedData = $request->validate([
'country_name' => 'required|max:255',
'symptoms' => 'required',
'cases' => 'required|numeric',
]);
Corona::whereId($id)->update($validatedData);
return redirect('/coronas')->with('success', 'Corona Case Data is successfully updated');
}
Step 9: Create Delete Functionality
編輯CoronaController destroy 方法：
// CoronaController.php
public function destroy($id)
{
$coronacase = Corona::findOrFail($id);
$coronacase->delete();
return redirect('/coronas')->with('success', 'Corona Case Data is successfully deleted');
}
整個CoronaController.php列表：
<?php
// CoronaController.php
namespace AppHttpControllers;
use IlluminateHttpRequest;
use AppCorona;
class CoronaController extends Controller
{
/**
* Display a listing of the resource.
*
* @return IlluminateHttpResponse
*/
public function index()
{
$coronacases = Corona::all();
return view('index', compact('coronacases'));
}
/**
* Show the form for creating a new resource.
*
* @return IlluminateHttpResponse
*/
public function create()
{
return view('create');
}
/**
* Store a newly created resource in storage.
*
* @param IlluminateHttpRequest $request
* @return IlluminateHttpResponse
*/
public function store(Request $request)
{
$validatedData = $request->validate([
'country_name' => 'required|max:255',
'symptoms' => 'required',
'cases' => 'required|numeric',
]);
$show = Corona::create($validatedData);
return redirect('/coronas')->with('success', 'Corona Case is successfully saved');
}
/**
* Display the specified resource.
*
* @param int $id
* @return IlluminateHttpResponse
*/
public function show($id)
{
//
}
/**
* Show the form for editing the specified resource.
*
* @param int $id
* @return IlluminateHttpResponse
*/
public function edit($id)
{
$coronacase = Corona::findOrFail($id);
return view('edit', compact('coronacase'));
}
/**
* Update the specified resource in storage.
*
* @param IlluminateHttpRequest $request
* @param int $id
* @return IlluminateHttpResponse
*/
public function update(Request $request, $id)
{
$validatedData = $request->validate([
'country_name' => 'required|max:255',
'symptoms' => 'required',
'cases' => 'required|numeric',
]);
Corona::whereId($id)->update($validatedData);
return redirect('/coronas')->with('success', 'Corona Case Data is successfully updated');
}
/**
* Remove the specified resource from storage.
*
* @param int $id
* @return IlluminateHttpResponse
*/
public function destroy($id)
{
$coronacase = Corona::findOrFail($id);
$coronacase->delete();
return redirect('/coronas')->with('success', 'Corona Case Data is successfully deleted');
}
}
最後，我自己在首頁index.blade.php加上一個”Add a new coron virus record”按鈕：
如果要反轉migration的過程，可以執行php artisan migrate:rollback來刪除coronas這個表格 (會執行down()函式)。
接著編輯Corona.php，來加入fillable的屬性：(設置’country_name’, ‘symptoms’, ‘cases’這三個欄位是可以填寫的。)
