Laravel 在模型中定义的视图中调用方法。不起作用

我的观点中有很多逻辑。我在我的一个模型中将其重构为方法。它们正在被识别，但实际上并不工作，因为IF不会随着数据库的改变而改变，以反映应该调用的不同方法

例如，我的代码最初是这样的，所有的逻辑都在视图中

@if($tenancy == null || $tenancy->accepted == 0 && $tenancy->request_sent != 1)
              <a href="/account/tenancy/{{$user->id}}/create" class="btn btn-primary">Start Tenancy</a>
            @endif


          <!-- 
            If the user signed in isn't the owner of this profile.
            Do not show these buttons that control accept/reject/end
          -->

        @if(Auth::user()->id == $user->id)
          <!-- 
            If the request has been sent but hasn't been accepted.
            Give the option to accept and reject.
            This updates the values in DB.
          -->
          @if($tenancy != null && $tenancy->accepted == 0 && $tenancy->request_sent == 1)
            <form method="POST" action="/account/tenancy/{{$user->id}}/accept">
              {{ csrf_field() }}
              <input type="submit" class="btn btn-primary" value="Accept Request">
            </form>
            <form method="POST" action="/account/tenancy/{{$user->id}}/reject">
              {{ csrf_field() }}
              <input type="submit" class="btn btn-warning" value="Reject Request">
            </form>
              <!-- 
                If the request has been accepted.
                Show button to end the tenancy,
                and property details
              -->
          @elseif($tenancy != null && $tenancy->accepted == 1 && $tenancy->request_sent == 0)
            <form method="POST" action="/account/tenancy/{{$user->id}}/end">
              {{ csrf_field() }}
              <input type="submit" class="btn btn-primary" value="End Tenancy">
            </form>
            <h5>Currently in Tenancy with {{$tenancy->landlord_name}}</h5>
            <h5>Your property is {{$tenancy->property_address}}</h5>
          @endif <!-- End of current user vs this user-->
        @endif <!-- Initial If-->

这是定义方法的租赁模型

public function addTenancy()
{
    return $this->accepted == 0 && $this->request_sent == 0;
}

public function hasRequestPending()
{
    return $this->accepted == 0 && $this->request_sent == 1;
}

public function inTenancy()
{
    return $this->accepted == 1 && $this->request_sent == 0;
}

我不明白为什么新的更新视图不应该随着数据库的变化而在IF语句中移动。有什么想法吗？

我认为您不能从数据库中获取雄辩的模型，而只能从表“租约”中获取第一行。您应该这样做

$book=App\book:：first（）但首先您必须将您的模型连接到数据库
@cash非常完美，非常感谢。如果您不想将此作为正式答案，我将接受最佳答案。您可能希望同时使用
租赁
和
租赁
作为变量名进行更改。“真令人困惑。”罗伯特。好主意。当数据库为空时，这不会失败吗？@Robert this将返回null，因此您应该检查该变量以避免不必要的错误
  public function index($id){

   $user = User::where('id', $id)->first();
   $users = Auth::user();
   $Tenancy = new Tenancy;
   $tenancy =  DB::table('tenancy')->first();

  return view('/pages/account/index', compact('user', 'users', 'Tenancy', 'tenancy'));
}

public function addTenancy()
{
    return $this->accepted == 0 && $this->request_sent == 0;
}

public function hasRequestPending()
{
    return $this->accepted == 0 && $this->request_sent == 1;
}

public function inTenancy()
{
    return $this->accepted == 1 && $this->request_sent == 0;
}
