Data gets overwritten in Json file

[shoeb]

Hi,

I'm not able to append mutliple data to Json file. My code is as;

void MainWindow::fileWriteOperationJson()
{
    QString filename = "C:/Users/..../save.json";
 
    QFile saveFile(filename);
    saveFile.open(QIODevice::WriteOnly|QIODevice::Text);
 
//    if (!saveFile.open(QIODevice::WriteOnly))
//    {
//          qWarning("Couldn't open save file.");
//    }
    QJsonObject json;
    write(json);
    QTextStream out(&saveFile);
 
    out << QJsonDocument(json).toJson(QJsonDocument::Indented);
 
}
 
 
 
void MainWindow::write(QJsonObject &json) const
{
    QJsonObject nameObj;
    nameObj["f_name"] = ui->lineEdit->text();
    nameObj["l_name"] = ui->lineEdit_2->text();
 
    QJsonArray personalData;
    personalData.append(nameObj);
    json["personal_Data"] = personalData;
 
    qDebug() << qlist;
}

void MainWindow::fileWriteOperationJson()
{
    QString filename = "C:/Users/..../save.json";

    QFile saveFile(filename);
    saveFile.open(QIODevice::WriteOnly|QIODevice::Text);

//    if (!saveFile.open(QIODevice::WriteOnly))
//    {
//          qWarning("Couldn't open save file.");
//    }
    QJsonObject json;
    write(json);
    QTextStream out(&saveFile);

    out << QJsonDocument(json).toJson(QJsonDocument::Indented);

}



void MainWindow::write(QJsonObject &json) const
{
    QJsonObject nameObj;
    nameObj["f_name"] = ui->lineEdit->text();
    nameObj["l_name"] = ui->lineEdit_2->text();

    QJsonArray personalData;
    personalData.append(nameObj);
    json["personal_Data"] = personalData;

    qDebug() << qlist;
}

To copy to clipboard, switch view to plain text mode 

My current output is as:

{
    "personal_Data": [
        {
            "f_name": "qqq",
            "l_name": "www"
        }
    ]
}

{
    "personal_Data": [
        {
            "f_name": "qqq",
            "l_name": "www"
        }
    ]
}

Please suggest how should i append the multiple info??

Thanks in advance

if you want a list of JSON objects representing people then you should use a QJsonArray (list) of QJSonObject (people).
