从数据库订购数据 - Eloquent - Laravel

Question

我正在尝试根据列值在表中显示数据，

我有一个名为 designation_id 的表 col，我想根据 ID 对结果进行分组并按特定顺序显示，

这是我目前为在我的刀片中实现的结果所做的，

我的控制者，

 $statemembers = StateChairman::find($id)->statemembers;

刀片

@foreach ($statemembers as $statemember)
    {{$statemember->first_name}}
<br>
<h4> President </h4>

@if ($statemember->designation_id == 'P')
{{$statemember->first_name}}
@else
    There are no members under the Chairman. Please add a new member under the chairman.    
@endif

<h4> Vice President </h4>
@if ($statemember->designation_id == 'VP')
{{$statemember->first_name}}
@else
    There are no members under the Chairman. Please add a new member under the chairman.    
@endif
@endforeach

等等，

由于 designation_id 是动态的，我想为我动态选择它。

模特，

class Statechairman extends Model
{
    public function statemembers(){
        return $this->hasMany('App\Statemembers','chairman_id','id');
    }
}


class Statemembers extends Model
{
    public function statechairman(){
        return $this->belongsTo('App\Statechairman','chairman_id','id');
    }

Answer 1

您可以通过这种方式对您的关系数据进行排序。

$statemembers = StateChairman::find($id)->statemembers()->orderBy('your_column')->get();
