Laravel（在所选问题中显示项目标题）

Question

我想在issue中显示所选项目的项目名称

HomeController（显示分配给用户的项目）

public function index()
{
    $companies = auth()->user()->companies;
    $projects  = Project::whereIn('company_id',$companies->pluck('id'))->get();

    return view('home',compact('companies','projects'));
}

ProjectController（显示所选项目的问题）

public function show($id){
    $project = Project::find($id);
    if(!$project)
        abort(404);

    $issues = $project->issues;
    return view('issues', compact('issues'));
}

issue.blade.php

<div class="container">

        <img src="assets/user.png" class="h-10 m-5 inline-block"><span class="font-bold text-xl">{{ auth()->user()->name }}</span>
        
        <span class="font-bold text-xl">{{ $project->title }}</span>
        <h1 class="ml-5 font-bold text-2xl">Issues</h1>
        <div class="grid grid-cols-3 gap-4 md:grid-cols-3 m-5 ">
            @forelse($issues as $issue)
                <div class="bg-pink-700 h-32 rounded-md p-5 transition duration-500 ease-in-out hover:bg-black transform hover:-translate-y-1 hover:scale-110s">
                    <a href="" class="text-xl font-bold m-5 text-white">{{$issue->title}}</a>
                </div>
            @empty

            @endforelse
    </div>
</div>

路线

Route::get('/home', [\App\Http\Controllers\HomeController::class, 'index'])->name('home');

Route::get('/issues/{id}', [\App\Http\Controllers\ProjectController::class, 'show'])->name('projects.show');

Answer 1

只是一个提示，而不是使用：

 $project = Project::find($id);
    if(!$project)
        abort(404);

您可以使用 $project = Project::findOrFail($id);

现在回答你的问题：

您可以将 $project 模型传递给视图，而不仅仅是问题。

public function show($id){
    $project = Project::findOrFail($id);
    return view('issues', compact('project'));
}

然后你可以通过你的foreach循环中的->issues关系得到相关问题：

<div class="container">
            ......
        <span class="font-bold text-xl">{{ $project->title }}</span>
            ......
        <div class="grid grid-cols-3 gap-4 md:grid-cols-3 m-5 ">
            @forelse($project->issues as $issue)
               .....
            @empty
              .....
            @endforelse
    </div>
</div>
