Question

我在pyqt中太新了，现在我有一个Raspberry Pi和pyqt的项目
在项目中我想显示从sql到tableview的数据
这是代码

import sys
import RPi.GPIO as GPIO
import time
import re    
import signal    
import MFRC522    
from PyQt4 import uic, QtCore, QtGui    
from PyQt4.QtCore import *    
from PyQt4.QtSql import *
from PyQt4.QtGui import *

GPIO.setwarnings(False) #Disables the Warning

db = QSqlDatabase.addDatabase("QMYSQL")
db.setDatabaseName("daftar")
db.setUserName("root")
db.setPassword("asdasd")
db.open()

permintaan = QSqlQuery()
permintaan.exec_("select * from data_aben")
lanjut=permintaan.next()
a=0
sql_data = permintaan.value(0).toString()

class test_absen(QtGui.QMainWindow):
        def __init__(self):
                super(test_absen, self).__init__()
                uic.loadUi('test_absen.ui',self)
                MIFAREReader = MFRC522.MFRC522()
                timer = QtCore.QTimer(self)
                timer.timeout.connect(self.timout)
                timer.start(1)

        def timout(self):
                MIFAREReader = MFRC522.MFRC522()
                (status,TagType) = MIFAREReader.MFRC522_Request(MIFAREReader.PICC_REQIDL)
                (status,uid) = MIFAREReader.MFRC522_Anticoll()
                lanjut=permintaan.next()
               c = permintaan.value(0).toString()
                self.mysqldata.setText(c)
                if status == MIFAREReader.MI_OK:
                        key = [0xFF,0xFF,0xFF,0xFF,0xFF,0xFF]
                        a = str(uid[0]) + str(uid[1]) + str(uid[2]) + str(uid[3])
                        self.lineEdit.setText(a)
                        if str(a) == permintaan.value(0).toString() :
                                nama = permintaan.value(2).toString()
                                nim = permintaan.value(1).toString()
                                self.label.setText(nama)
                                self.output.setText(nim)

if __name__ == '__main__':
        app = QtGui.QApplication(sys.argv)
        MainWindow = QtGui.QMainWindow()
        window = test_absen()
        window.show()
        sys.exit(app.exec_())`

现在你的问题是如何从sql到table view显示数据我真的希望得到帮助抱歉英语不好：D 先于
