Problem with setFilter(), sql lite

[Pato55]

Hi I have problem with my project, I have database and I don't know how to display in QTableView only what I want to find in database. I have button for adding and for deleting too, but button for finding don't work.

this is my code
query = new QSqlQuery(db);
query->exec("CREATE TABLE IF NOT EXISTS Filmy (Jméno TEXT,Žánr TEXT,Hodnocení INTEGER,Poznámky TEXT, PRIMARY KEY(Jméno));");

model = new QSqlTableModel(this, db);

model->setTable("Filmy");

model->select();
model->setHeaderData(0, Qt::Horizontal, "Název");
model->setHeaderData(1, Qt::Horizontal, "Žánr");
model->setHeaderData(2, Qt::Horizontal, "Hodnocení");
model->setHeaderData(3, Qt::Horizontal, "Poznámky");
model->setSort(2, Qt::DescendingOrder);
ui->tableView->resizeColumnsToContents();
ui->tableView->horizontalHeader()->setSectionsClickable(true);
ui->tableView->horizontalHeader()->setSectionsMovable(true);
ui->tableView->setSortingEnabled(true);


ui->tableView->setModel(model);

this is function for search button

void MainWindow::on_pushButton_3_clicked()
{ // vratim to co jsem napsal
model = new QSqlTableModel(this, db);
const QString edit = ui->lineEdit->text();
model->setTable("Filmy");
//qDebug()<<edit;
model->setFilter("Název == Pád do tmy");
//model->setFilter(QString("Název = '%1'").arg(edit));
model->select();
ui->tableView->setModel(model);

I work in qt creator. Thank you for every response

model->setFilter("Název == Pád do tmy");

What about:

model->setFilter("Název = 'Pád do tmy'");

@jsulm No, It doesn't work. I don't why

[jsulm]

@Pato55 From documentation (https://doc.qt.io/qt-5/qsqltablemodel.html#setFilter): "The filter is a SQL WHERE clause without the keyword WHERE". But in your create table query there is no column called "Název", so how should this work?

@jsulm Yes, I created table with bad name, thank you for saving my study life :)
