Laravel - How to update Input Array without deleting Sales Detail - laravel

Question

In my Laravel-8 project, I have this controller for Input Field Array Update.
Controller:
public function update(UpdateSaleRequest $request, $id)
{
try {
$sale = Sale::find($id);
$data = $request->all();
$update['date'] = date('Y-m-d', strtotime($data['date']));
$update['company_id'] = $data['company_id'];
$update['name'] = $data['name'];
$update['remarks'] = $data['remarks'];
$sale->update($update);
SaleDetail::where('sale_id', $sale->id)->delete();
foreach ($data['invoiceItems'] as $item) {
$details = [
'sale_id' => $sale->id,
'item_id' => $item['item_id'],
'employee_id' => $item['employee_id'],
'quantity' => $item['qty'],
'price' => $item['cost'],
'total_price' => $item['cost'] * $item['qty'],
'sale_type_id'=>$item['sale_type_id']
];
$saleDetail = new SaleDetail($details );
$saleDetail->save();
}
} catch (JWTException $e) {
throw new HttpException(500);
}
return response()->json($sale);
}
In the form, the user can add more Sales Detail or remove.
Some of the SaleDetail fields are being used somewhere else.
Is there a way to update the input field array without deleting the SaleDetail as shown in what I did here:
SaleDetail::where('sale_id', $sale->id)->delete();
Thanks

I've tried to restructure your code so that's easier to edit. I've left some comments. I can really recommend refactoring.guru. There you will find many ways to improve your code so that it is more extensible, maintainable and testable. If you have any questions, please feel free to ask.
class Sale extends Model
{
// Use a relationship instead of building your own query
public function details() {
return $this->hasMany(SaleDetail::class);
}
}
class SaleDetail extends Model
{
// Use a computed property instead of manually calculating total price
// You can access it with $saleDetail->totalPrice
public function getTotalPriceAttribute() {
return $this->price * $this->quantity;
}
}
class UpdateSaleRequest extends Request
{
public function authorize() {
return true;
}
protected function prepareForValidation() {
$this->merge([
// Create a Carbon instance by string
'date' => Carbon::make($this->date)
]);
}
public function rules() {
// Your validation rules
// Please also validate your invoice items!
// See https://laravel.com/docs/8.x/validation#validating-arrays
}
}
// We let Laravel solve the sale by dependency injection
// You have to rename the variable name in ihr web.php
public function update(UpdateSaleRequest $request, Sale $sale)
{
// At this point, all inputs are validated!
// See https://laravel.com/docs/8.x/validation#creating-form-requests
$sale->update($request->validated());
// Please ensure, that all properties have the same name
// In your current implementation you have price = cost, be consistent!
foreach($request->input('invoiceItems') as $invoiceItem) {
// How we can consider that a detail is already created?
// I assume that each item_id will only occur once, otherwise you'll
// place the id of each detail in your update form (e.g. in a hidden input)
$candidate = $sale->details()
->where('item_id', $properties['item_id'])
->first();
if($candidate) {
$candidate->update($properties);
} else {
$sale->details()->create($properties);
}
}
// A JWT-Exception should not be necessary, since your authentication
// will be handled by a middleware.
return response()->json($sale);
}
I have not tested the code, few adjustments may be needed.

Laravel has a method called updateOrCreate as follow
/**
* Create or update a record matching the attributes, and fill it with values.
*
* #param array $attributes
* #param array $values
* #return \Illuminate\Database\Eloquent\Model|static
*/
public function updateOrCreate(array $attributes, array $values = [])
{
return tap($this->firstOrNew($attributes), function ($instance) use ($values) {
$instance->fill($values)->save();
});
}
That means you could do some thing like
public function update(UpdateSaleRequest $request, $id)
{
try {
$sale = Sale::find($id);
$data = $request->all();
$update['date'] = date('Y-m-d', strtotime($data['date']));
$update['company_id'] = $data['company_id'];
$update['name'] = $data['name'];
$update['remarks'] = $data['remarks'];
$sale->update($update);
foreach ($data['invoiceItems'] as $item) {
$details = [
'item_id' => $item['item_id'],
'employee_id' => $item['employee_id'],
'quantity' => $item['qty'],
'price' => $item['cost'],
'total_price' => $item['cost'] * $item['qty'],
'sale_type_id'=>$item['sale_type_id']
];
$sale->saleDetail()->updateOrCreate([
'sale_id' => $sale->id
], $details);
}
} catch (JWTException $e) {
throw new HttpException(500);
}
return response()->json($sale);
}
I would encourage you to refactor and clean up your code.You can also read more about it here https://laravel.com/docs/8.x/eloquent#upserts
