我正在尝试建立一个系统，其中当Etudiant选择Theme时，Theme张贴者收到此Theme已被该{ {1}}。就我而言，主题海报是特定的Etudiant。它们各自的结构：
Utilisateur
Utilisateur <?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUtilisateursTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('utilisateurs', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('nom');
$table->string('prenom');
$table->string('username')->unique();
$table->string('email')->unique();
$table->string('password');
$table->string('fonction');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('utilisateurs');
}
}
Etudiant <?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateEtudiantsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('etudiants', function (Blueprint $table) {
$table->bigIncrements('id');
$table->integer('utilisateur_id')->unique();
$table->integer('matricule');
$table->string('grade');
$table->string('filiere');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('etudiants');
}
}
Theme为了注册<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateThemesTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('themes', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('intitule')->unique();
$table->string('description');
$table->string('categorie');
$table->string('cycle');
$table->string('filiereDesiree');
$table->integer('themePoster_id');
$table->string('themePoster_type');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('themes');
}
}
所做的Theme的所有选择，我创建了具有以下结构的表Etudiant：
etudiantsChoixThemes创建<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateEtudiantsChoixThemesTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('etudiantsChoixThemes', function (Blueprint $table) {
$table->bigIncrements('id');
$table->integer('idEtudiant');
$table->integer('idThematique');
$table->string('description');
$table->string('outils');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('etudiantsChoixThemes');
}
}
时，我会像这样获得主题海报的属性
Theme并且当<input type="hidden" id="themePoster_id" name="themePoster_id" value= "{{Auth::guard('web')->user()->id}}">
<input type="hidden" id="themePoster_type" name="themePoster_type" value= "{{Auth::guard('web')->user()->fonction}}">
选择Etudiant时，我得到的是这样的值
Theme使用ajax提交的<input type="hidden" name="idEtudiant" value=" {{Auth::guard('web')->user()->id}} ">
<input type="hidden" name="idThematique" value=" {{$theme->id}} ">
刀片视图表单中的
studentChooseTheme这是为了对我的数据库以及我正在尝试做的事情有更全面的了解。
好吧，我的问题与我上面所说的“通知”一起使用。我正在尝试做数据库通知。我已经关注了doc和另一个教程1 2，但是并没有真正理解全部内容。我遵循了这些步骤，进行了@extends('layouts.layout')
@section('content')
<body>
{{$theme->intitule}} {{$theme->categorie}}
<div class="container_fluid">
<div class="row">
<div class="alert alert-danger print-error-msg" style="display: none;">
<ul></ul>
</div>
<div class="alert alert-success print-success-msg" style="display: none;">
<center></center>
</div>
</div>
</div>
<form method="post" action=" {{route('registerThemeChoice', $theme->id)}} ">
@csrf
<fieldset>Comment comprenez-vous la thématique proposée</fieldset>
<input type="hidden" name="idEtudiant" value=" {{Auth::guard('web')->user()->id}} ">
<input type="hidden" name="idThematique" value=" {{$theme->id}} ">
<textarea name="description" required>{{old('description')}}</textarea>
<fieldset>Quels outils comptez-vous utiliser pour mener à bien le projet?</fieldset>
<textarea name="outils" required>{{old('outils')}}</textarea>
<input class="button-info" type="submit" name="submit" id="submit" value="Valider">

<a href=" {{url('themes/' .$theme->id)}} "><button class="button-danger">Annuler</button></a>
Thématique postée par {{ $themePoster_id }} {{$userThemePoster->prenom}} {{$userThemePoster->nom}}
</body>
@jquery
<script type="text/javascript">
$(function(){
$('#submit').on('click', function(e){
e.preventDefault();
var _token = $("input[name='_token']").val();
var idEtudiant = $('input[name=idEtudiant]').val();
var idThematique = $('input[name=idThematique]').val();
var description = $('textarea[name=description]').val();
var outils = $('textarea[name=outils]').val();
var textareasbothnotEmpty = (description != '' && outils!='');
if (textareasbothnotEmpty){
var c = confirm('Confirmez-vous les informations entrées?');
if(c){
$.ajax({
url: "{{route('registerThemeChoice',$theme->id)}}",
type: 'POST',
data: {
_token:_token,
idEtudiant:idEtudiant,
idThematique:idThematique,

},
success: function(data){
if($.isEmptyObject(data.error)){
// alert(data.success);
$('.print-error-msg').css('display','none');
toastr.success(" Votre choix est enregistré ");
}
else{
// console.log(data.error);
printErrorMsg(data.error);
}
}
});
}
else{
// alert('Annulé');
}
}
function printErrorMsg (msg) {
$(".print-error-msg").find("ul").html('');
$(".print-error-msg").css('display','block');
$.each( msg, function( key, value ) {
$(".print-error-msg").find("ul").append('<li>'+value+'</li>');
});
}
});
});
</script>

表的迁移，创建了通知文件并在控制器中进行了设置：
notifications
StudentChoosedThemeNotification <?php
namespace App\Notifications;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
class StudentChoosedThemeNotification extends Notification
{
use Queueable;
protected $EtudiantsChoixTheme
/**
* Create a new notification instance.
*
* @return void
*/
public function __construct($EtudiantsChoixTheme)
{
$this->EtudiantsChoixTheme = $EtudiantsChoixTheme;
}
/**
* Get the notification's delivery channels.
*
* @param mixed $notifiable
* @return array
*/
public function via($notifiable)
{
return ['database'];
}
// /**
// * Get the mail representation of the notification.
// *
// * @param mixed $notifiable
// * @return \Illuminate\Notifications\Messages\MailMessage
// */
// public function toMail($notifiable)
// {
// return (new MailMessage)
// ->line('The introduction to the notification.')
// ->action('Notification Action', url('/'))
// ->line('Thank you for using our application!');
// }
/**
* Get the array representation of the notification.
*
* @param mixed $notifiable
* @return array
*/
public function toDatabase($notifiable)
{
return [
'EtudiantsChoixTheme' => $this->EtudiantsChoixTheme,
];
}
}
studentChooseThemeController但是，当我提交时，没有像我想的那样在数据库中记录新的通知实例，而且我不再从<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Theme;
use App\Utilisateur;
use App\EtudiantsChoixTheme;
use Illuminate\Support\Facades\Validator;
use Illuminate\Validation\Rule;
use App\Notifications\StudentChoosedThemeNotification;
class studentChooseThemeController extends Controller
{
public function index($id){
$theme = Theme::findOrFail($id);
$themePoster_id = $theme->themePoster_id;
$userThemePoster = Utilisateur::where('id', '=', $themePoster_id)->first();
return view('studentChooseTheme', compact('theme', 'themePoster_id', 'userThemePoster'));
}
public function etudiantChoixTheme(Request $request, $id){
// $theme = Theme::findOrFail($id);
$validator = Validator::make($request->all(),[
'description' => 'required',
'outils' => 'required',
'idThematique' => Rule::unique('etudiantsChoixThemes')->where(function ($query) {
return $query->where('idEtudiant', request('idEtudiant'))
->where('idThematique', request('idThematique'));
})
]);
if ($validator->fails()) {
return response()->json(['error'=>$validator->errors()->all()]);
}
$etudiantChoixTheme = new EtudiantsChoixTheme;
$etudiantChoixTheme->idEtudiant = $request->input('idEtudiant');
$etudiantChoixTheme->idThematique = $request->input('idThematique');
$etudiantChoixTheme->description = $request->input('description');
$etudiantChoixTheme->outils = $request->input('outils');
$etudiantChoixTheme->save();
$choosenTheme = Theme::where('id', '=', $etudiantChoixTheme->idThematique)->first();
$userPoster = Utilisateur::where('id', '=', $choosenTheme->themePoster_id)->first();
$EtudiantsChoixTheme = [
'text' => 'Un étudiant a choisi son theme'
];
Notification::send($userPoster, new StudentChoosedThemeNotification($EtudiantsChoixTheme));
}
}
发送Toastr成功消息，尽管它记录了选择。
我在那里做错了吗？这是我第一次在laravel中使用通知。您的帮助或澄清将不胜感激
答案 0 :(得分：0)
检查通知是否正在排队，那么您可能必须运行队列服务器
php artisan queue:work
