self.cur = connection.cursor()
patient_name = self.lineEdit.text()
medecin_name =self.comboBox.currentText()
date_f = datetime.date.today()
time_f = datetime.datetime.now().time()
self.cur.execute(''' INSERT INTO transactions(patient, medecin, date_d, time_d, montant, C_acte, acte, users_id )

connection.commit()
self.lineEdit.setText('')
self.Show_tran_table()
def Show_tran_table(self):
database = QSqlDatabase("QPSQL")
database.setHostName("localhost")
database.setDatabaseName("database")

database.open()
model_ft = QSqlTableModel(db=database)
model_ft.setTable('transactions')

self.tableView.setModel(model_ft)

model_ft.setFilter(filter_ft)
if __name__ == '__main__':
app = QApplication(sys.argv)
app.setStyle('Fusion')
#app.setWindowIcon(QtGui.QIcon('sifax.ico'))
window = MainApp()
window.show()
sys.exit(app.exec_())

I try a simple solution that it refresh the table every specific time using this
timer = QTimer(self)
timer.timeout.connect(self.Show_tran_table)
timer.start(5000)
but I get into another problem when I want to update a value in the table I have to be faster than 5 s or the table will refresh and I can't update any value
this gui work on 2 part the first one is for adding data and the 2nd part is for showing data only (the same thing here, but only the table view), what I want when someone add data to the database using the def Handel_Day_Operations_1 (self):in the 2 nd gui that contain only the table view it will refresh automatically with the new row that has been added
