how to update array in laravel 5? - laravel-5

Question

I am trying to update values from an array.
i can create but if I try to update, it updates only last value.
if I use save() i get an error. I tried everything i could researching. no success.
here is my code.
$products = $request->all();
$name = $products['name'];
$price = $products['price'];
$qty = $products['qty'];
$total = $products['total'];
foreach( $name as $key => $n) {
$invoice->products()->update([
'invoice_id' => $invoice->id,
'name' => $name[$key],
'price' => $price[$key],
'qty' => $qty[$key],
'total' => $total[$key]
]);
}
if I use save() i get this error
Argument 1 passed to Illuminate\Database\Eloquent\Relations\HasOneOrMany::save() must be an instance of Illuminate\Database\Eloquent\Model, array given,

thanks for your help Mr. pyramid. here is the code:
public function update(Request $request, $id)
{
$invoice = Invoice::findOrFail($id);
$invoice->invoice_no = $request->invoice_no;
$invoice->client = $request->client;
$invoice->title = $request->title;
$invoice->client_address = $request->client_address;
$invoice->invoice_date = $request->invoice_date;
$invoice->due_date = $request->due_date;
$invoice->subtotal = $request->subtotal;
$invoice->grandtotal = $request->grandtotal;
$invoice->save();
$products = $request->all();
$name = $products['name'];
$price = $products['price'];
$qty = $products['qty'];
$total = $products['total'];
foreach( $name as $key => $n) {
$invoice->products()->update([
//=> $invoice->id,
'name' => $name[$key],
'price' => $price[$key],
'qty' => $qty[$key],
'total' => $total[$key]
]);
}
Session::flash('success', 'Invoice Updated');
return redirect()->route('invoices');
}
with this exactly code I can create and works fine but if i use to update it won't allow me.
database
Schema::create('invoices', function (Blueprint $table) {
$table->increments('id');
$table->integer('invoice_no');
$table->date('invoice_date');
$table->date('due_date');
$table->string('title');
$table->string('client');
$table->string('client_address');
$table->decimal('subtotal');
$table->decimal('grandtotal');
$table->timestamps();
});
products
Schema::create('products', function (Blueprint $table) {
$table->increments('id');
$table->integer('invoice_id')->unsigned();
$table->string('name');
$table->string('qty');
$table->string('price');
$table->string('total');
$table->timestamps();
});
relationship
class Invoice extends Model {
protected $fillable =['client','client_address','title','invoice_no','invoice_date','due_date','discount', 'subtotal','grandtotal'];
public function products(){
return $this->hasMany('App\Product', 'invoice_id');
}
}
class Product extends Model
{
protected $casts = [
'name' => 'array',
'price' => 'array',
'qty' => 'array',
'total' => 'array'
];
protected $fillable = ['invoice_id','price','qty','total','name'];
public function invoice(){
return $this->belongsTo('App\Invoice');
}
}
thanks

I still have some doubts but I found something which I think can help you.
$invoice->products()->update($request->all());

Answer 3

$products = $request->all();
$name = $products['name'];
$price = $products['price'];
$qty = $products['qty'];
$total = $products['total'];
foreach( $name as $key => $n) {
$invoice->products()->create([
'invoice_id' => $invoice->id,
'name' => $name[$key],
'price' => $price[$key],
'qty' => $qty[$key],
'total' => $total[$key]
]);
}
