• Laravel Vuejs 实战：开发知乎 （34-36）私信列表

    1.控制器：

      1 php artisan make:controller InboxController

    文件代码如下：

      1 <?php
  2 
  3 namespace AppHttpControllers;
  4 
  5 use IlluminateHttpRequest;
  6 
  7 
  8 class InboxController extends Controller
  9 {
 10     public function __construct()
 11     {
 12         $this->middleware('auth');
 13     }
 14 
 15     //
 16     public function index()
 17     {
 18         $messages = auth()->user()->messages->groupBy('from_user_id');
 19 //        $messages->map(function ($message) {
 20 //            return $message->map(function ($item) {
 21 ////                return $item->with('user');
 22 //                return $item->fromUser;
 23 //            });
 24 //        });
 25         return view('inbox.index', compact('messages'));
 26     }
 27 
 28     public function show($userId)
 29     {
 30         $messages = auth()->user()->messages->where('from_user_id', $userId);
 31 
 32         return view('inbox.show', compact('messages'));
 33     }
 34 }
 35 
 36
    InboxController.php

    from_user_id是 在messages表中的字段

    2.view文件：

    /inbox/index.blade.php:

      1 @extends('layouts.app')
  2 @section('content')
  3     <div class="container">
  4         <div class="row">

  9                 <div class="card-body">
 10 
 11                     @forelse($messages as $messageGroup)
 12                         <div class="card">
 13                             <div class="card-header">

 15                                     <img src="{{ $messageGroup->first()->fromUser->avatar }}"
 16                                          alt="{{ $messageGroup->first()->fromUser->name }}"

 18                                     {{ $messageGroup->first()->fromUser->name }}
 19                                 </a>
 20                             </div>
 21                             <div class="card-body">
 22                                 <p class="text-success "> 查看详细对话请点击：</p>
 23                                 <a href=" {{ route('inbox.show', $messageGroup->first()->fromUser->id) }}"
 24                                    class="btn btn-block bg-light"> {{ $messageGroup->first()->content }}</a>
 25                             </div>

    /inbox/show.blade.php:

      1 @extends('layouts.app')
  2 @section('content')
  3     <div class="container">

    show.blade.php

    fromUser属性是 Message.php模型文件中定义的模型关联

    批注 2020-03-04 003714

    3.route路由 web.php添加：

      1 #region
  2 //用户查看短消息
  3 Route::get('/inbox', 'InboxController@index')->name('inbox.index');
  4 
  5 //展示用户间私信对话具体内容页
  6 Route::get('/inbox/{userId}', 'InboxController@show')->name('inbox.show');
  7 
  8 #endregion
  9 
 10

    4.回复私信及其展示代码实现：

    回复的数据提供给视图：

      1 <?php
  2 
  3 namespace AppHttpControllers;
  4 
  5 use AppMessage;
  6 use AppUser;
  7 use IlluminateHttpRequest;

 14         $this->middleware('auth');
 15     }
 16 
 17     //
 18     public function index()
 19     {
 20         $messages = auth()->user()->messages->groupBy('from_user_id');

 22 //            return $message->map(function ($item) {
 23 ////                return $item->with('user');
 24 //                return $item->fromUser;
 25 //            });
 26 //        });
 27         return view('inbox.index', compact('messages'));
 28     }
 29 
 30     public function show($userId)
 31     {
 32         $messages = auth()->user()->messages->where('from_user_id', $userId);
 33
