Laravel ORM Eloquent无法在共享主机上正常工作，但在本地可以正常运行

编程问答 2022-08-22

问题描述

当我尝试使用Laravel的Eloquent从表单模型从外键获取值时，这里出现错误Trying to get property 'form' of non-object (View: /home/laravel/web/laravel.swt101.eu/public_html/abonamenty/resources/views/invoices/show.blade.php)。在这一行：{{ $invoice->form->form }}。我有雄辩的一些问题，不得不多次使用没有Eloquent的数据库。相同的代码可以很好地用于另一个视图（形式），它具有与发票相同的功能，但是在共享主机上不会出错。 invoices.show视图中的{{ $invoice->form->form }}仅在本地主机上有效。我不知道怎么回事。有谁能够帮助我？请。如果服务器出现问题，有人可以帮助我为Laravel Eloquent配置共享托管吗？

这是共享错误的链接。我仅在共享主机上收到此错误。在本地工作正常 https://flareapp.io/share/x7XVWgma

这是我的发票模型

<?php


namespace App;

use App\Form;
use Kyslik\ColumnSortable\Sortable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;


class Invoice extends Model
{
    /**
     * The attributes that are mass assignable.
     *  
     * @var array
     */
    use SoftDeletes;
    use Sortable;
    

    
    protected $table = 'invoices';

    
    protected $fillable = [
        'invoicenumber','invoicedate','id','selldate','user_id','paymentmethod','paymentdate','status','comments','city','paid','autonumber','automonth','autoyear','name','PKWIU','quantity','unit','netunit','nettotal','VATrate','grossunit','grosstotal','form_id','currency_id',];
    
    public $sortable = [ 'invoicenumber',];
    
    protected $dates = ['deleted_at'];
    public $primaryKey = 'id';
    

    
        public function user()
    {
        return $this->belongsTo('App\User');
    }

        public function form()
    {
        return $this->hasOne('App\Form','form_id');
    }    

         public function currency()
    {
        return $this->hasOne('App\Currency');
    }
   
        public function proform()
    {
        return $this->belongsTo('App\Proform');
    } 
    
}

这是我的表单模型：

    <?php

namespace App;
use App\Invoice;
use Kyslik\ColumnSortable\Sortable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;


class Form extends Model
{
    //
     protected $table= 'forms'; 

        protected $fillable = [
        'id','form',];
    
        public function invoice()
    {
        return $this->belongsTo('App\Invoice','form_id');
    }  
    
    
    
        public function proform()
    {
        return $this->belongsTo('App\Proform');
    }
}

这是控制器的显示方法：

    public function show(Invoice $invoice)
    {
        $users = User::all('showname','id');
        $forms = Form::all('id','form');
        $currencys = Currency::all('id','currency','course'); 
        $query = DB::table('forms')
            ->join('invoices','forms.id','=','invoices.form_id');

        $query1 = DB::table('currencys')
            ->join('invoices','currencys.id','invoices.currency_id');
      
/*$invoice2 = Invoice::with('form')->find($invoice->id);*/
 $invoice2 = Invoice::find($invoice->id);     
 $form = $invoice2->form;
 $invoice->id;
 /*  dd($invoice2->form);    */

      

       
        return view('invoices.show',compact('users','forms','currencys','invoice','query','query1','invoice2'));
        
        
        
    }

这是我的表演视图：
