为查看、编辑和删除按钮创建关系，并在 laravel 应用程序中为相应的货件显示特定的 view/page

Question

谁能帮我解决这个问题，我一直在尝试在我的网站页面上获取货件上的查看、编辑和删除按钮 table，以便在单击时显示相应货件按钮的视图.但是视图必须针对每个装运，其中 link 放置在 table 行中，即每组行按钮应显示 [=33] 上特定装运数据的视图=]行。

这是我的 blade 模板，用于显示所有装运 table:

<table id="shipment-list" class="table table-hover table-sm">
            <thead>
                <tr>
                    <th class="form-check">
                        <input class="form-check-input " id="wpcfe-select-all" type="checkbox">
                        <label class="form-check-label" for="materialChecked2"></label>
                    </th>
                    <th>Tracking Number</th>
                    <th class="no-space">Shipper Name</th>
                    <th class="no-space">Receiver Name  </th>
                    <th>Status</th>
                    <th>Shipment Type</th>                              
                    <th class="text-center">View</th>
                    <th class="text-center">Print</th>
                    <th class="text-center">Update</th>
                    <th class="text-center">Delete</th>
                </tr>
            </thead>
            <tbody>
                    @if(count($shipment) >0)
                    @foreach($shipment as $shipment)

                <tr id="shipment-2928" class="shipment-row pending">
                    <td class="form-check">

                    <td><a href="#" class="text-primary font-weight-bold" name="tracking_code">{{$shipment->tracking_code }}</a></td>
                    <td class="no-space">{{$shipment->sender_name }}</td>
                    <td class="no-space">{{$shipment->receiver_name }}</td>
                    <td class="shipment-status pending">{{$shipment->status }}</td>
                    <td class="shipment-type default">{{$shipment->shipment_type }}</td>

        </tbody>
        </table>
    </div>

这里是家庭控制器，显示所有出货量(admin-index)page/view:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Shipment;
use DB;

class HomeController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Contracts\Support\Renderable
     */
    public function index()
    {
        $page_title = "Admin Dashboard";
        $shipment = Shipment::latest()->get();
        return view('home', compact('shipment','page_title'));
        
      
    }
}

这是我在装运控制器中尝试使用 table 上的按钮显示单个视图的方法。但我知道这离我应该做的还差得远:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Str;
use App\Shipment;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\MessageBag;




class ShipmentController extends Controller
{
   
    /**
     * Create a new user instance after a valid registration.
     *
     * @param  Request  $request
     * @return \App\Shipment
     */
    protected function store(Request $request)
    {
        
        $shipment = new Shipment();

        $data  = $this->validate($request, [
            'sender_name' => 'required|string|max:255',
            'sender_email' => 'required|string|email|max:255',
            'receiver_email' => 'required|string|email|max:255',
            'sender_address' => 'required|string',
            'estimated_Date' => 'required||date|after:today',
            'shipment_type' => 'required|string|max:255',
            'content' => 'required|string|max:255', 
            'receiver_name' => 'required|string|max:255', 
            'receiver_address' => 'required|string|max:255', 
            'sender_country' => 'required|string|max:255', 
            'sender_telephone' => 'required|string|max:255',
            'comments' => 'required|string|max:255',
            'receiver_telephone' => 'required|string|max:255',
            'receiver_country' => 'required|string|max:255',
            'package_weight' => 'required|string|max:255',
            
        ]);
        

        $shipment->sender_name = $request->input('sender_name');
        $shipment->receiver_email= $request->input('receiver_email');
        $shipment->sender_email= $request->input('sender_email');
        $shipment->sender_address= $request->input('sender_address');
        $shipment->estimated_Date= $request->input('estimated_Date');
        $shipment->shipment_type= $request->input('shipment_type');
        $shipment->content= $request->input('content');
        $shipment->receiver_name= $request->input('receiver_name');
        $shipment->receiver_address= $request->input('receiver_address');
        $shipment->sender_country= $request->input('sender_country');
        $shipment->sender_telephone= $request->input('sender_telephone');
        $shipment->comments= $request->input('comments');
        $shipment->receiver_telephone= $request->input('receiver_telephone');
        $shipment->receiver_country= $request->input('receiver_country');
        $shipment->package_weight= $request->input('package_weight');
        $shipment->tracking_code = strtoupper(Str::random(20));
        
        $shipment->save();   

           
            return redirect('/index')->with('Success', 'Your Shipment has been created');
       
    }

    public function tracking(Request $request){

        $this->validate($request,
            [
                'tracking_code' => 'required|max:25',

            ]);

        $shipment = Shipment::where('tracking_code', $request->input('tracking_code'))->first();
        
        if ( $shipment == null)
        {
            
            return redirect('/shipment/track')->with('error', 'Incorect Tracking Number');
            
        }
        else{
            return view('shipment.single')->with('shipment', $shipment);
        }

    }



    public function single(request $request ){

        $page_title = "view shipment";
        $tracking_code = Shipment::get()->tracking_code;
        $shipment= Shipment::where('tracking_code', $tracking_code)->first();
        
        return view('shipment.single', compact('tracking_code','shipment','page_title'));
       
    }
    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $request
     * @return \Illuminate\Http\Response
     */
    public function edit(Request $request)
    {
        $shipment = Shipment::where($shipment->tracking_code );

        //check for Admin user
        if (Gate::allows('isAdmin')) {

            return view('shipment.edit')->with('shipment', $shipment);
            
        }else {
            return redirect('/home')->with('error', 'Unauthorized Page');
        }
       
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        
    }

这是我的路线：

Route::get('/single', 'ShipmentController@single')->name('single');

Route::get('/shipment/createnew', 'PagesController@createnew');

Route::Post('/shipment/storenew', 'ShipmentController@store')->name('storenew');

Route::get('/shipment/edit', 'ShipmentController@edit')->name('edit');



Route::Post('/tracking', 'ShipmentController@tracking')->name('tacking');

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

如何创建一个关系，当单击相应的查看、编辑和删除按钮时，该关系可用于获取特定货件？我的数据库 table 上的每批货物都有一个唯一的 ID 和 tracking_code 列。如何使用它们作为关系？

Answer 1

在您的 foreach loop 中，因为您有一列用于 delete 和 edit，因此您可以拥有类似的内容。我只为 edit

这样做

Blade 查看

<td class="text-center">
<a href="{{route('shipment.edit',$shipment->id)}}" class="wpcfe-edit-shipment" data-id="2928" title="Edit"><i class="fa fa-edit text-primary"></i></a>
</td>

web.php

Route::get('/shipment/edit/{shipment}', 'ShipmentController@edit')->name('shipment.edit');

控制器

public function edit(Shipment $shipment){
return view('shipmentview',compact('shipment'));
}

您可以按照以下相同的方式进行删除。

blade 查看

<td class="text-center">
    <a href="{{route('shipment.delete',$shipment->id)}}" class="wpcfe-edit-shipment" data-id="2928" title="Delete"><i class="fa fa-trash text-danger"></i></a>
    </td>

web.php

Route::get('/shipment/{shipment}/delete', 'ShipmentController@delete')->name('shipment.delete');

控制器

public function delete(Shipment $shipment){
$shipment->delete();
return back();
}

为查看、编辑和删除按钮创建关系，并在 laravel 应用程序中为相应的货件显示特定的 view/page
