我想从数据库表中获取记录列表。这些是插入数据库的两个列名“id”和“lable”的值。

INSERT INTO "phone_number_type" VALUES(1,'Home');
INSERT INTO "phone_number_type" VALUES(2,'Work');
INSERT INTO "phone_number_type" VALUES(3,'Mobile');
INSERT INTO "phone_number_type" VALUES(4,'Mistress');
INSERT INTO "phone_number_type" VALUES(5,'Meth Dealer');

我只想将列名“标签”放入 QComboBox。这是我的代码:

import sys
import sqlite3

from PyQt5 import QtSql
from PyQt5.QtSql import QSqlDatabase
from PyQt5.QtWidgets import QMainWindow, QApplication
from combobox import Ui_MainWindow


class fetchrec(QMainWindow, Ui_MainWindow):
    def __init__(self):
        QMainWindow.__init__(self)
        self.setupUi(self)
        db = QSqlDatabase.addDatabase("QSQLITE")
        db.setDatabaseName("ttest.db")
        self.model = QtSql.QSqlTableModel(self)
        self.model.setTable("phone_number_type")
        self.comboBox.setModelColumn(self.model.fieldIndex("lable"))
        self.comboBox.setModel(self.model)


if __name__ == "__main__":
    import sys

    app = QApplication(sys.argv)
    userins = fetchrec()
    userins.show()
    sys.exit(app.exec_())
