Php 显示与id和基于角色的分类相关的结果-Laravel

我有两位主席和成员

主席席

id | first_name | from | to | row_status 

-----------------------------------------
1 | old Chairman | 3-2017 | 5-2018 | 0
2 | Chairman | 6-2018 | 4-2018 | 1

成员表

id | chairman_id | | Name | role | row_status

-------------------------------------------
1 |  1 | president | P | 0
2 |  1 | vice president | VP | 0
3 |  2 | president | p | 1
4 |  2 | vice president | VP | 1

我试图根据主席的从-到期间显示活跃（row_Status=1）主席和成员

如果有多个主席，我不知道如何显示结果

我现在显示的结果如下：

刀片页

    @foreach ($statechairmans as $statechairman)
        <li>
            {{$statechairman -> first_name}}
        </li>

        <li> {{ $statechairman->statemembers->first_name }} </li>
    @endforeach

我能够按预期查看结果，但我不确定如何根据角色处理数据

我如何根据用户的角色显示用户，并在有更多用户的情况下访问多个主席

例如

@foreach（$stateechairmans作为$stateechairman）

{{$statephairman->first_name}

{{$statechairman->statemembers->first_name}
@如果（$statechairman->row_status==1）
发件人：{{$statephairman->from}
致：{{$STATEPROMIATION->to}
@恩迪夫
@endforeach

---

希望有帮助：）

谢谢@Maulik，以上面的答案为基础，我也添加了角色，**在if（$statechairman->statemembers->Assignment_id='VP'）角色：{{{{$statechairman->statemembers->first_name}在endif**

State Chairman 
  public function statemembers(){
        return $this->belongsTo('App\Statemembers', 'id','chairman_id');
    }

State Members

public function statechairman(){
        return $this->hasMany('App\Statechairman');
    }

Active
Chairman -> President -> Vice-President -> etc,

Old Chairman - 3-2017 | 5-2018
Chairman -> President -> Vice-President -> etc,

@foreach ($statechairmans as $statechairman)
        <li>
            {{$statechairman -> first_name}}
        </li>

        <li> {{ $statechairman->statemembers->first_name }} </li>
        @if($statechairman->row_status == 1)
             from : {{ $statechairman->from}}
             to:  {{ $statechairman->to}}
        @endif
@endforeach
