Question

我目前有一个这样的模型 -

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class UserSlidePhoto extends Model
{
    protected $table="users_slides_photos";
    protected $fillable=['user_id','social_image_id','original_image_name','provider_key','provider_id','thumbnail_name'];

    public $timestamps = true;

    public function users()
    {
        return $this->belongsTo('App\User')->withTimestamps();
    }
}

这样的控制器 -

public  function rearrangePhotoMonth(Request $request)
{
    //$ordering = $request->input('ordering');
    $thumbs = url('/uploads/userfiles/thumbs/')."/";
    $images = url('/uploads/userfiles/images/')."/";

    return UserSlidePhoto::where('user_id', Auth::id())
                  ->selectRaw(
                                "
                                DATE_FORMAT(created_at, '%M, %Y') as month,
                                id,
                                CONCAT('".$thumbs."',thumbnail_name) AS thumbnail_url,
                                CONCAT('".$images."',original_image_name) AS original_image_url"
                              )
                  ->groupBy('month')
                  ->orderBy('month', 'desc')
                  ->get();
}

我正在收到像这样的JSON响应 -

[
  {
    "month": "November, 2019",
    "id": 7,
    "thumbnail_url": "http:\/\/localhost:8000\/uploads\/userfiles\/thumbs\/2-aZa54HnAqwY2DPMlSVI2UpbRohVTlY.png",

  },
  {

    "id": 5,
    "thumbnail_url": "http:\/\/localhost:8000\/uploads\/userfiles\/thumbs\/2-r6jxeFfV7nnLrMxO5l88sC7Pt0Xq1A.png",
    "original_image_url": "http:\/\/localhost:8000\/uploads\/userfiles\/images\/2-r6jxeFfV7nnLrMxO5l88sC7Pt0Xq1A.png"
  },

    "original_image_url": "http:\/\/localhost:8000\/uploads\/userfiles\/images\/2-YgLYcr5DsB3kHjpa7cxcznjiEFdzeF.png"
  }
]

但我喜欢这样的反应 -

    "data": {
      {
        "id": 6,
        "thumbnail_url": "http:\/\/localhost:8000\/uploads\/userfiles\/thumbs\/2-WujsXF8iNSuwxQX4QRebKkOqFinlJV.png",
        "original_image_url": "http:\/\/localhost:8000\/uploads\/userfiles\/images\/2-WujsXF8iNSuwxQX4QRebKkOqFinlJV.png"
      },
      {

        "original_image_url": "http:\/\/localhost:8000\/uploads\/userfiles\/images\/2-VcgQcjoi0iXM2YOqhgt0fYUZf8kwsE.png"
      },
      {

      }
    }
  }
]

有人可以帮忙吗？

Answer 1

您的查询错误，只需运行它以查看每个月只返回一行。

所以你需要删除 group_by 子句并在PHP中手动执行或使用laravel collections

Answer 2

我已经这样解决了 -

public  function rearrangePhotoMonth(Request $request)
{
    //$ordering = $request->input('ordering');
    $thumbs = url('/uploads/userfiles/thumbs/')."/";
    $images = url('/uploads/userfiles/images/')."/";

    $collection = UserSlidePhoto::where('user_id', Auth::id())
                  ->selectRaw(
                                "
                                DATE_FORMAT(created_at, '%M, %Y') as month,
                                id,
                                CONCAT('".$thumbs."',thumbnail_name) AS thumbnail_url,
                                CONCAT('".$images."',original_image_name) AS original_image_url"
                              )
                  ->orderBy('created_at', 'desc')
                  ->get();

    return collect($collection)
            ->groupBy('month')
            ->all();
}

现在正在运作:)。

group by每月只会给你一行。

除非有一些雄辩的魔法我还不知道（这很可能是真的），你必须通过PHP解析数组以组织你的数据。
