Laravel 中的数据检索问题

Question

我正在尝试在我的刀片中显示一些数据。 以下是控制器（ActivateController.php）索引 function 的当前代码，

 public function index($id)
    {
        //echo $id;
        $datas = Website::WHERE('appId','=',$id);
        //dd($datas);
        return view('activities.index',compact('datas','id'));         
    }

我的观点 url 有点像，

TEST.site/activities/index/12

这是我的刀片，index.blade.php

@extends('layouts.admin')


@section('content')
<div class="container">
<div class="row">
    <div class="col-sm">
        <div class="pull-left">
            <h2 class="mt-2">Activate Website</h2>
        </div>
        <div class="pull-right">
            <a class="btn btn-primary" href="{{ route('websites.index') }}"> Back</a>
        </div>
    </div>
</div>
</div>

@if (count($errors) > 0)
<div class="container ">
<div class="row">
<div class="col-sm">
  <div class="alert alert-danger mt-2">
    <strong>Whoops!</strong> There were some problems with your input.<br><br>
    <ul>
       @foreach ($errors->all() as $error)
         <li>{{ $error }}</li>
       @endforeach
    </ul>
  </div>
</div>
</div>
</div>
@endif

<div class="container mt-3">
<div class="row">
<div class="col-sm">


@foreach ($datas as $object)

<form id="w1" action="{{ route('activities.update',$object->appId) }}" method="POST">
                        @csrf
                        @method('PUT')
                        <strong>Select Package Type:<span class="star">*</span></strong>
                        <input type="text" name="app_domain" value="{{$object->domain}}">
                            <strong>Select Package Type:<span class="star">*</span></strong>
                            <select id="app-packagetype" class="form-control" name="package_type" aria-required="true">
                                <option value="{{$object->payment_option }}">{{$object->payment_option }}</option>
                                <option value="monthly">Monthly [12]</option>
                                <option value="yearly">Yearly [99]</option>
                            </select>
                        <br>
                        <div class="form-group text-right">
                            <button type="submit" class="btn btn-success">{{ __('Activate') }}</button>
                        </div>

</form>
 @endforeach

</div>
</div>
</div>
@endsection

但现在我的问题是，当我尝试检索数据时，

{{$object->appId}}

它检索空....

我在哪里做错了以及如何将数据正确地检索到视图中？

Answer 1

你最后缺少get()

改变这个：

$datas = Website::where('appId','=',$id);

至

$datas = Website::where('appId','=',$id)->get();

谢谢..

Answer 2

你就这样使用

$datas = Website::where('appId',$id)->get();
