Question

如何将数据分组并获得数组中数据的所有值

示例

id name    date       public
1  hi   2018-10-19    true
2  hai  2018-10-20    true
3  bye  2018-10-19    true

比我想要的响应json

data:{
"2018-10-19": [
  {
     "name": "hi",
     "public": true
  },
  {
     "name": "bye",
     "public": true
  }
 ],
 "2018-10-20": [
  {
     "name": "hai",
     "public": true
  }
 ],
}

我尝试

$ data = DB :: table（'calendar'）-> select（'date'）-> groupBy（'date'）-> orderBy（'date'，'asc'）-> get（）; < / p>

    return response()->json(['status'=>'success','data'=>$data]);

Answer 1

您可以在laravel查询中使用groupBy：

public function calendar($id)
{
  #Calendar is a model name. 
  #data is relationship in Calendar model.

  $calendar = Calendar::whereHas('data', function ($query) use($id) {
    $query->where('id',$id);
  })->get()->groupBy(column_name_you_want_to_group_by);
    return response()->json([$calendar],200);
}

Answer 2

您可以在laravel集合中使用groupBy。

// retch the data from the databse as a collection.
$data_collection_from_the_database = ....;

// to group by date
$grouped_collection = $data_collection_from_the_database->groupBy->date;

// to get json
$grouped_collection->toJson();

Answer 3

尝试

$data = DB::table('calendar')->orderBy('date','asc')->get()->groupBy('date')->toArray();

如何使响应json groupby并获得分组的所有值
