无法在雄辩的laravel 5.1中建立hasMany关系

Question

Hi I am new to laravel and trying to make one to many relationship where I am trying to get customer name from customers and order_no against the customer name from orders table, here is code

//--customer Model
class customer extends Model {
  public function order(){
    return $this->hasMany('App\order');
 }
}

//-- order Model
class order extends Model {
    public function customer(){
    return $this->belongsTo('App\customer');
       }
     }

  //--controller
  public function searchRecord(){
  $customer = customer::all();
  return view('orders.searchRecord')->with('customer', $customer);
  }

  //--View

 @foreach($customer as $customer)                                        
 {{$customer->customer_name}}<br />
 @endforeach

when I use {{$customer->customer_name}} it prints all customer name fine, but when I use {{$customer->order}} it prints the whole json of order table, but if I {{$customer->order->order_no}} it gives error undefined property $order_no.

Answer 1

You have defined your customer->order relation as one-to-many , which means that a single customer can have multiple orders . Therefore, when you access $customer->order you are accessing a Collection object that stores all customer's order, not a single order. There is no order_no property in Collection class, that's why you're getting the error.

One way to access invidual orders you'll need to iterate through the collection:

foreach ($customer->order as $order) {
  echo $order->order_no;
}
