php - 如何精简 Laravel ORM

Question

不好意思，这个问题太蠢了..

我使用Controller，有很多ORM，我想精简这段代码。

我的 Controller

public function news(Request $request)
{
    $history = Recruitments_status::where('recruitments_status.status',1)->get();
    $history_a =  Recruitments_status::where('recruitments_status.status',2)->get();
    $history_b = Recruitments_status::where('recruitments_status.status',3)->get();  
    $history_c = Recruitments_status::where('recruitments_status.status',4)->get(); 
    $history_d = Recruitments_status::where('recruitments_status.status',5)->get(); 
    $history_e = Recruitments_status::where('recruitments_status.status',6)->get(); 

    return view('pl_sidebar/news',[
          'history' => $history,
          'history_a' => $history_a,
          'history_b' => $history_b,
          'history_c' => $history_c,
          'history_d' => $history_d,
          'history_e' => $history_e
    ]);
}

如何精简这个ORM代码？

Answer 1

您的代码将生成多个查询，这是不好的做法。你可以获得一个集合:

public function news(Request $request)
{
    return view('pl_sidebar/news', [
        'history' => Recruitments_status::whereIn('status', [1, 2, 3, 4, 5, 6])
    ]);
}

然后在 Blade 模板中使用这个集合:

@foreach ($history->where('status', 1) as $single)
     {{ $single->status }}
     {{ $single->id }}
@endforeach
