Laravel excel, update rows after save in DB - php

Question

Project in Laravel (9), and PHP (8.1).
I want to import an excel file and use maatwebsite/excel (3.1) package.
I can import a file, and save the file into the model, like this:
import class:
class BankTransfersHistoryImport implements ToModel, WithHeadingRow, WithValidation, WithBatchInserts
{
use Importable;
private $rows;
public function __construct()
{
$this->rows = collect();
}
/**
* #param array $row
*
* #return \Illuminate\Database\Eloquent\Model|null
*/
public function model(array $row)
{
$bankTransferHistory = new BankTransfersHistory([
'loanId' => $row['loanId'],
'actionDate' => transformDate($row['actionDate']),
'worth' => $row['worth'],
.
.
]);
$this->rows->push($bankTransferHistory);
return $bankTransferHistory;
}
/**
* Returns Imported Data
*
* #return \Illuminate\Support\Collection
*/
public function getImportedData(): \Illuminate\Support\Collection
{
return $this->rows;
}
public function headingRow(): int
{
return 2;
}
public function rules(): array
{
return [
'*.loanId' => ['required', 'numeric'],
... some roles ...
];
}
}
controller:
public function store(Request $request)
{
$request->validate([
'file' => 'required|mimes:xls,xlsx',
]);
$file = $request->file('file');
$import = new BankTransfersHistoryImport;
try {
// date validation
$collection = $import->toCollection($file);
... some validation about the date ...
$import->import($file);
$getImportedData = import->getImportedData();
... check and update rows ...
return [
"message" => some message,
"data" => [
some data
],
];
} catch (\Maatwebsite\Excel\Validators\ValidationException$e) {
$failures = $e->failures();
foreach ($failures as $failure) {
$failure->row(); // row that went wrong
$failure->attribute(); // either heading key (if using heading row concern) or column index
$failure->errors(); // Actual error messages from Laravel validator
$failure->values(); // The values of the row that has failed.
}
return $failures;
}
My question is:
If I can get the response of the file after saving the data, that will give me the data with the id of the row that was saved.
In some cases, I will have to update a row. That's why I would like to get the ID.
Now, in the check and update rows section, I update row by loanId + actionDate. I want it to be done by only ID.
something like this:
code:
$getImportedData = import->getImportedData();
data will be like:
[
{
"id": 1,
"loanId": 21001,
"actionDate": "2020-01-02T00:00:00.000000Z",
"worth": 2997.09,
"offerId": 1,
},
{
"id": 2,
"loanId": 21002,
"actionDate": "2020-01-02T00:00:00.000000Z",
"worth": 3000,
"offerId": 10,
},
]

Answer 1

The solution to my problem.
To save the information and get the ID of each saved row, I did a few things.
I changed my import class.
First I changed the create from ToModel to ToCollection
I deleted WithBatchInserts because this method does not work with ToCollection.
Next, I called the getImportedData function.
That's how I got all the rows I create in the DB with their ID.
This solved the problem for me to get the information saved with the ID of each line, and perform validation + update if necessary.
The code is below.
A small note:
I changed the word rows to data in the `getImportedData' function.
I save all the files in the system.
import class:
class BankTransfersHistoryImport implements ToCollection, WithHeadingRow, WithValidation
{
use Importable;
private $data;
public function __construct()
{
$this->data = collect();
}
/**
* #param array $row
*
* #return \Illuminate\Database\Eloquent\Model|null
*/
public function collection(Collection $rows)
{
foreach ($rows as $row) {
$bankTransferHistory = BankTransfersHistory::create([
'loanId' => $row['loanId'],
'actionDate' => transformDate($row['actionDate']),
'worth' => $row['worth'],
.
.
]);
$this->data->push($bankTransferHistory);
}
}
/**
* Returns Imported Data
*
* #return \Illuminate\Support\Collection
*/
public function getImportedData(): \Illuminate\Support\Collection
{
return $this->data;
}
public function headingRow(): int
{
return 2;
}
public function rules(): array
{
return [
'*.loanId' => ['required', 'numeric'],
... some roles ...
];
}
}
store controller:
public function store(Request $request)
{
$request->validate([
'file' => 'required|mimes:xls,xlsx',
]);
$file = $request->file('file');
$import = new BankTransfersHistoryImport;
try {
// date validation
$collection = $import->toCollection($file);
... some validation about the date ...
// save the file in the system
$fileName = time() . '-' . $file->getClientOriginalName();
$file->storeAs('import bank transfers history', $fileName);
$import->import($file);
$importedData = $import->getImportedData(); // data after save in DB
... check and update rows ...
return [
"message" => some message,
"data" => [
some data
],
];
} catch (\Maatwebsite\Excel\Validators\ValidationException$e) {
$failures = $e->failures();
foreach ($failures as $failure) {
$failure->row(); // row that went wrong
$failure->attribute(); // either heading key (if using heading row concern) or column index
$failure->errors(); // Actual error messages from Laravel validator
$failure->values(); // The values of the row that has failed.
}
return $failures;
}
}
