【问题描述】：

我正在开发 laravel 5.2。我想显示属于此时打开的特定组的那些成员。实际上，我正在获取我存储在我的数据库中的所有成员，但是我只想访问或显示那些属于我当前正在访问的特定对象的成员。我收到一个错误：方法组不存在。如下所示：

我的控制器：

    public function members($id){
    $dashes=Grouptable::findorFail($id);
    $members=Member::all();
    return view('members' , ['dashes'=>$dashes,'members'=>$members]);

     }

    public function dashboard($id){
    $dashes=Grouptable::findorFail($id);
    return view('dashboard' , ['dashes'=>$dashes]);

    }
    public function addmembers(Request $request){
    $member=new Member();
    $member->members=$request['addmember'];
    $request->groups()->members()->save($member);

    return redirect()->back();
    }

我的看法：

    <body>
    <div class="row">
    <div class="col-lg-3 col-lg-offset-1">
    <img src="images/ImgResponsive_Placeholder.png" 
    class="img-circle img-  responsive" alt="Placeholder image"> </div>
    <div class="col-lg-7">
    <h1 style="color:black;">{{ $dashes->name }}</h1></div>
    <br />
    </div>
    <div class="row">

   <div class="col-lg-3">

   <button class="btn btn-success"  onclick="myFunction()">
   Add Members +   </button>
    <div>

   <form id="demo" style="display:none;" method="post"
   action="{{ route('addmember') }}">
    <input class="form-control" type="text" name="addmember">
    <button class="btn btn-primary" type="submit">Add</button>
    <input type="hidden" name="_token" value="{{ Session::token() }}">
    </form>

    </div>
     </div>

     <div class="col-lg-7 col-lg-offset-0">
     <div class="panel panel-default">
     <div  id="grp" class="panel-heading">
     <h3 id="grouptitle" class="panel-title">Group Members</h3>
     </div>
     <div  id="zx" class="panel-content">
     <div class="row">
        @foreach($members as $member)
        <section class="col-md-6">

         <div class="row">

        <section class="col-md-offset-1 col-md-3 col-xs-offset-1 col-xs-4">
       <img id="imagesize" src="images/g.jpg" class="img-circle"/>
       </section>
        <section class="col-md-offset-1 col-md-7 col-xs-7">
          <section class="col-md-12">

            <h5 id="friendname">{{$member->members}}</h5>

          </section>
          <section class="col-md-12">
            <button type="button" class="btn btn-sm btn-
            default">Score</button>
             </section>
              </section>
               </div>

               <div class="row">
               <section class="col-md-offset-9 col-md-3 col-xs-offset-6 
            col-xs-4">
            <div class="btn-group">
            <button id="btnclr1" type="button" class="btn btn-block
             btn-warning dropdown-toggle" data-toggle="dropdown" aria-
           expanded="false"><span class="caret"></span></button>
            <ul id="bckdrp" class="dropdown-menu" role="menu">
              <li role="presentation"><a id="drpmenu" href="#">Remove</a>
              </li>
            </ul>
          </div>
            </section>
             </div>
             <div class="row">
             <section class="col-md-offset-1 col-md-10">
          <hr>
           </section>
           </section>
            @endforeach

             </div>
              <div id="mn" class="panel-footer"><a id="seemr1"
              href="#.html">See More</a></div>
               </div>
                </div>
              </div>
                </div>
             </div>
             </div>
                </div>
             </body>

我的路线：

         Route::get('/members/{id}',[
        'uses'=>'GroupController@members',
          'as'=>'members'
           ]);
           Route::get('/dashboard/{id}',[
          'uses'=>'GroupController@dashboard',
          'as'=>'dashboard'
          ]);
           Route::post('/memeber/add',[
           'uses'=>'GroupController@addmembers',
          'as'=>'addmember'
           ]);

我的模态：

        Grouptable:
        public function members(){
        return $this->hasMany('App\Member');
          }

        Member:

         public function groups(){
    return $this->belongsTo('App\Grouptable');
            }

【问题讨论】：

您正试图将其保存在Request $request 上，它不具备群组功能。您可能希望将其保存在 $members 上。
对不起，我没找到你

【解决方案1】：

我不太了解整个问题，但是

public function addmembers(Request $request){
    $member=new Member();
    $member->members=$request['addmember'];
    $request->groups()->members()->save($member);

    return redirect()->back();
}

应该看起来更像

public function addmembers(Request $request){
    $member=new Member();
    $member->propertyX = $request->get('propertyX');
    $member->propertyY = $request->get('propertyY');
    $member->groups()->attach($group); // FOR MANY-TO-MANY (N-N) RELATION
    $member->groups()->associate($group); // FOR ONE-TO-MANY (1-N) RELATION
    $member->save();

    return redirect()->back();
}

根据您的迁移，您应该选择 attach() 或 associate()
