Laravel 显示 0 而不是数据库中保存的值
Laravel Shows 0 instead of saved value in database
我的网络显示有问题 id Supplier
列显示值 0
当保存的值不是 0
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);
}
/**

public function create()
{

/**

/**

除 idSupplier
列
外,其他列可以显示与数据库中相同的值
编辑
当我将模型中的主键从 idSupplier
更改为 id
时,不知何故。问题已解决,视图中的列 id supplier
显示与数据库相同的值。
试试这个。
Supplier::where('idSupplier',$id)->get();
注意:Laravel findOrFail() 这个函数总是寻找 table 主 ID。当您使用自己的自定义主 ID 时,您应该在模型文件中将其定义为主键。
如果您的 主键 是 idSupplier
那么您必须使用
在您的模型中:
public $incrementing = false;
在你的控制器中:
public function show($id)
{
$supplier = Supplier::where('idSupplier',$id)->first();
return view('suppliers.show')->with('suppliers', $supplier);
}
