<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Order extends Model
{
    //

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

in the root file

Route::get('orders',function(){
    $orders=App\Order::find(1);
    echo "<pre>";
    foreach($orders as $order){
        echo $order->name."Order by ".$order->customer->name."<br />";
    }
});

It show error Trying to get property of non-object

Answer 1

You are not adding customer entries in your function. To do so do the following:

Route::get('orders',function(){
    $orders=App\Order::find(1)->customer();// this will add customer entries to your order
    echo "<pre>";
    foreach($orders as $order){
        echo $order->name."Order by ".$order->customer->name."<br />";
    }
});

Update:

Route::get('orders',function(){
        $orders=App\Order::with('customer')->all()->get();// add with()
        echo "<pre>";
        foreach($orders as $order){
            echo $order->name."Order by ".$order->customer->name."<br />";
        }
    });
