Laravel在数据库中显示0而不是保存的值

Question

我在我的网络节目id Supplier列中显示值0时遇到问题 当保存的值不是0时

我的数据库在哪里

这是我的控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Supplier;

class SuppliersController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $suppliers = Supplier::all();
        return view('suppliers.index')->with('suppliers', $suppliers);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        $supplier = Supplier::find($id);
        return view('suppliers.show')->with('suppliers', $supplier);
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

这是我的模特

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Supplier extends Model
{
    // Table Name
    protected $table = 'suppliers';
    // Primary Key
    protected $primaryKey = 'idSupplier';
    // Timestamps
    public $timestamps = true;
}

这是我的观点

@section('content')

    <div class="navbar navbar-light bg-light">

其他列可以显示与数据库中相同的值，除了idSupplier列

编辑

当我以某种方式将模型中的主键从idSupplier更改为id时。视图中已解决问题的列id supplier与数据库显示相同的值。

Answer 1

尝试一下。

Supplier::where('idSupplier',$id)->get();

注意：Laravel findOrFail（）这个函数总是在寻找表的主ID。当您使用自己的自定义主ID时，应在模型文件中将其定义为主键。

Answer 2

如果您的主键为idSupplier，则必须使用

在您的模型中：

public $incrementing = false; 

在您的控制器中：

 public function show($id)
    {
        $supplier = Supplier::where('idSupplier',$id)->first();
        return view('suppliers.show')->with('suppliers', $supplier);
    }
