尝试阅读属性和“用户”在布尔
用户ID显示BOOL错误，我会通过使用删除从列表中删除的位置保留列表
我对Laravel 9有一个问题，每当我单击删除时， 模型
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Doctor_review extends Model
{
use HasFactory;
public $timestamps = false;
protected $primaryKey = 'doctorReviewID';
}
这是我的控制器部分
$reviews = Doctor_review::all();
return view('admin.docreviews')->with('doctor_reviews', $reviews);
}
public function deletereview(Request $request){
$review = Doctor_review::where('doctorReviewID', $request->doctorReviewID)->first();
return view('admin.docreviews')->with('doctor_reviews', $review);
}
public function deletereviewSubmit(Request $request){
$review = Doctor_review::where('doctorReviewID', $request->doctorReviewID)->first();
$review->delete();
return redirect()->route('docreviews');
}
}
，这是我的刀片页面
@extends('layouts.appAdmin')
@section('contentAdmin')
<table class = "table table-border">
<tr>
<th>Patient ID</th>
<th>Doctor ID</th>
<th>Description</th>
<th>Rating</th>
</tr>
@foreach($doctor_reviews as $review)
<tr>
<td>{{$review->userID}}</td>
<td>{{$review->doctorID}}</td>
<td>{{$review->description}}</td>
<td>{{$review->point}}</td>
<td><a href="/deletereview/{{$review->doctorReviewID}}">Delete</a></td>
</tr>
@endforeach
@endsection
，这是我的删除表单页面

如果您想打电话给 - ＆gt;请确保您的用户ID不是布尔或无效。您可以在刀片中进行{{{dd（$评论 - ＆gt; userId）}}，以查看用户ID的值。
your userID value is boolean, if you want to call with -> please make sure your userID is not boolean or null. You can do {{ dd($review->userID) }} in your blade to see the value of userID.
没有完整的错误消息，我无法确定。但这是我的猜测：
这将为表格添加了评论列表，当您foreach时，您将循环浏览列表。
这将为表格添加单个评论，当您foreach时，您将循环浏览其属性。
可能会解决您的问题。但是我建议将刀片页面分配到列表查看页面和详细查看页面。
Without the full error message I can't really know for sure. But this is my guess:
This adds a list of reviews to the form, and when you foreach, you will loop through the list.
This will add a single review to the form, and when you foreach, you will loop through its properties.
Might fix your issue. But I'd suggest splitting the blade page into a list view page and a detail view page.
在两个函数中，您返回具有不同类型的变量的视图。
您正在使用 foreach循环读取两种类型的变量，即收集和单个值。
first（）将返回元素本身，并且可以在刀片文件中为：
和 all（）将返回a Collection 。
访问集合的数据 $评论在刀片文件循环中使用：
In two functions you are returning to one view with different type of variables.

first() will return element itself and can be in blade file as:
And all() will return a Collection.
To access data of collection $review in blade file loop is used i.e.:
