Question

我的观点中有很多逻辑。我将其重构为我的一个模型中的方法。它们被识别，但实际上没有工作，因为IF不会随着数据库的变化而改变，以反映应该调用的不同方法。

例如，我的代码最初是这样的，视图中包含所有逻辑。

interface Climb {
    boolean isTooHigh(int height, int limit);
}
public class Main {
    public static void main(String[] args) {
        check((h,l) -> h>l, 5);
    }
    private static void check(Climb climb, int height) {
            System.out.println(climb.isTooHigh(height, 10) ? "Too":"ok" );
    }
}

然后我使用方法名称而不是logc重构它。这些方法在我的租赁控制器中定义。

@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-->

这是呈现上方视图的控制器

@if(Auth::user()->id == $tenancy->tenant_id)
          <h1>You cannot add yourself</h1>
        @elseif($Tenancy->addTenancy())
          <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->hasRequestPending())
        <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($Tenancy->inTenancy())
        <form method="POST" action="/account/tenancy/{{$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 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'));
}

我无法理解为什么新更新视图不应该随着数据库更改而在IF语句中移动。有什么想法吗？

我认为你不会从数据库中获得雄辩的模型，但只能从表'Tenancy'获得第一行，你应该做这样的$book = App\Book::first();，但首先你必须将你的模型连接到数据库

在视图中调用方法，这些方法在模型中定义。不工作
