[SOLVED] retrieve data using model relationship laravel 4

retrieve data using model relationship laravel 4

I'm really confused why I keep getting a null value when retrieving data from my data model.

Here's my model:

class Supplier extends Eloquent {

  public function purchase_orders()
  {
    return $this->hasMany('Purchase_order','supplier_id');
  }
}

And my controller:

    $purchase_orders  = Supplier::find(1)->purchase_orders;
    dd($purchase_orders);

This results to NULL.

My Purchase_order table's fields are:

('id','supplier_id','name','status','date')

And my Suppliers table's fields are:

('id','name','email', 'address')

Solution

By the help of @hayhorse I discovered that the one causing the issue was the underscore on the name of the class, to solve the issue i just renamed my class from purchase_orders to purchaseOrder and by that i can now user the proper syntax which is:

$purchase_orders = Supplier::find(1)->purchase_orders;

again credits to @hayhorse
