Update many multiple data with tables hasmany and belongsTo?

Question

sorry for my english

I want two tables

Invoices

• id
• user_id
• name
• created_at
• update_at

Invoicesitems

• id
• invoice_id
• title
• createad_at
• update_at

Models

class Invoices extends eloquent{
   public function invoicesitems(){
       return $this->hasMany('Invoicesitem');
   }
}

class Invoicesitems extends eloquent{
   public function invoices(){
       return $this->belongsTo('Invoice');
   }
}

Now, for update the items of my invoices? Example my invoices have 5 item, i need update to 10 items

first delete all items of my invoices and insert new ???

$invoices = Invoices::findOrFail($id);
$dataupdate = array(
  'user_id' => Input::get('user'),
  'name' => Input::get('name'),
);
$invoices->fill($dataupdate);
$invoices->save();

//Ok update invoices, now how to update items? Thanks you.

If your business logic allows - you can just replace the invoice items.

$invoice = Invoices::findOrFail($id);
$dataupdate = array(
    'user_id' => Input::get('user'),
    'name' => Input::get('name'),
 );
 $invoice->update($dataupdate);

 // replace invoice items
 $invoice->invoicesitems()->delete();
 $invoice->invoicesitems()->create($invoiceItems);

Note! This is quite straight solution. You can improve by using insert() method instead of create() for batch insert.
