Model Relationships

Hi all I'm trying to set up multiple relationships on my models, Im trying to display my orders in a table along with a users address. ( i have it working for the users model).

(background) I'm creating an e-commerce platform in short

Users model

<?php

namespace App;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class User extends Authenticatable implements MustVerifyEmail
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'title', 'first_name', 'last_name', 'phone_number', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];


    public function Address(){
        return $this->hasOne('App\Address');
    }


}

My Orders Model

class Orders extends Model
{
    protected $primaryKey = 'user_id';

    protected $fillable = [
        'user_id', 'slot_id', 'note', 'total_weight', 'item_count', 'total', 'status'
    ];

    public function Address(){
        return $this->hasOne('App\Address');
    }
}

My Address Model

class Address extends Model
{
    protected $table = 'address';

    protected $primaryKey = 'user_id';
    
    protected $fillable = [
        'post_code', 'address_line_1', 'address_line_2', 'address_line_3', 'city'
    ];

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

    public function Orders()
    {
        return $this->hasOne('App\Orders');
    }
}

When i try to pull the data in my view

@foreach($orders as $order)
                        <tr>
                            <th>{{ $order->id }}</th>
                            <th>{{ formatPrice($order->total) }}</th>
                            <th>{{ $order->address->post_code }}</th>
                        </tr>
  @endforeach

i Get this error

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'address.orders_user_id' in 'where clause' (SQL: select * from address where address.orders_user_id in (1))

Im not 100% sure what is going on but I dont think it is matching the user_id in the orders table to the user_id in the address table

Thanks in advance for any help
