python数据未插入sqlite数据库错误

Question

嗨，我想插入数据到sqlite数据没有插入。 错误消息

代码中的MY函数

def addstudent(self):

        b2 = self.a2.text()
        b3 = self.a3.text()
        b4 = self.a4.text()
        b5 = self.a5.text()
        b6 = self.a6.text()
        b7 = self.a7.text()
        b8 = self.a8.text()
        b9 = self.a9.itemText(self.a9.currentIndex())
        b10 = self.a10.itemText(self.a10.currentIndex())
        b11 = self.a11.itemText(self.a11.currentIndex())
        b12 = self.a12.text()
        b13 = self.a13.itemText(self.a13.currentIndex())
        b14 = self.a14.itemText(self.a14.currentIndex())
        b15 = self.a15.text()
        b16 = self.a16.itemText(self.a16.currentIndex())
        try:
            conn = sqlite3.connect("collage_App.db")
            dbs = conn.cursor()
            dbs.execute("""INSERT INTO student_registration VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, , ?, ?) """ , (b2,b3,b4,b5,b6,b7,b8,b9,b10,b11,b12,b13,b14,b15,b16, arrow.now().format('YYYY-MM-DD')) )
            conn.commit()
            conn.close()

            QMessageBox.information(QMessageBox(),'Successful','Student is added successfully into database.')
            self.close()
        except Exception:
            QMessageBox.warning(QMessageBox(), 'Error', 'Could not add student to the database.')

我的按钮事件代码

#Submit Button Clicked
        self.add.clicked.connect(self.addstudent)

您需要删除try-except子句并发布实际错误。

另一方面，使用Django处理数据库会更好。在https://www.djangoproject.com/start/中查看其教程。它不那么容易出错，并且为使用模型提供了一个很好的界面。
