如何将我的 Eloquent 集合转换为 JSON？

Question

我的数据库输出是这样的：

[{"id":1,"domain":"test","email":"test@mail.com","status":"pending"},{"id":3,"domain":"tester","email":"lorem@ipsum.ml","status":"pending"}]

如果转换为 JSON：

[
  {
    "id": 1,
    "domain": "test",
    "email": "test@mail.com",
    "status": "pending"
  },
  {
    "id": 3,
    "domain": "tester",
    "email": "lorem@ipsum.ml",
    "status": "pending"
  }
]

我想像这样按字母（所有字母）对它们进行分组：

[
  "a" :{

    }
  "b" :{

    }
  "l" :{
    "id": 3,
    "domain": "lorem",
    "email": "lorem@ipsum.ml",
    "status": "pending"
  }
  "t":{
    "id": 1,
    "domain": "test",
    "email": "test@mail.com",
    "status": "pending"
  },

]

这样我就可以通过使用{{ $json[$char'] or 'No directories in ' . $char}} 轻松地在视图中显示它们。 $char 来自循环@foreach (range('A', 'Z') as $char)

这是来自我的控制器：

public function all()
  {
    $data = Subdomain::all();

    return view('directories.all' , ['data' => $data]);

  }

我的观点是：

@foreach (range('A', 'Z') as $char)

  <div class="col-md-3">
    <div class="panel panel-info">
      <div class="panel-heading">
        <h3 class="panel-title">{{$char}}</h3>
      </div>
      <div class="panel-body">

      </div>
      <div class="panel-footer">

      </div>
    </div>

  </div>

  @endforeach

这是 var_dump：

Answer 1

如果你想使用完整的 Laravel，请使用集合的力量：

Route::get('/json', function() {
    $json = '[{"id":1,"domain":"test","email":"test@mail.com","status":"pending"},{"id":3,"domain":"tester","email":"lorem@ipsum.ml","status":"pending"}]';

    $letters = collect(array_combine(range('a', 'z'), array_fill(1, 26, [])));

    $grouped = collect(json_decode($json))->groupBy(function ($item) {
        return $item->email[0];
    });

    dd($letters->merge($grouped));
});

你应该得到

Answer 2

您不需要 JSON，您会得到一个带有 $data = Subdomain::all(); 的集合。只需使用where() 和like 即可搜索电子邮件以字符开头的所有行：

@foreach (range('A', 'Z') as $char)
    // Some HTML here.
    @foreach ($data->where('email', 'like', $char) as $row)
        {{ $data->domain}} {{ $data->email }}
    @endforeach
    // Some HTML here.
@endforeach

Answer 3

我得到了答案。感谢@alexey 提出将查询放入刀片模板的想法。

答案就这么简单（Alexey 忘了用 get()），

  @foreach ($data->where('domain', 'like', $char . '%)->get() as $row)

        {{$row->domain}}

        @endforeach

但我想要干净。 所以我在模型（子域）中创建了一个范围。

public function scopeCategory($query, $char)
    {
      $query->where('domain', 'like',  $char . '%')->get();
    }

并在我的刀片视图中执行此操作：

 <div class="panel-body">
        @foreach (\App\Subdomain::category($char)->get() as $row)

        {{$row->domain}}

        @endforeach


      </div>
