嗨，我对python很新，所以请帮助，即使你觉得我在问一个愚蠢的怀疑。问题是我正在创建五个lineedits，必须通过单击按钮提取值。但问题是点击按钮我得到interfaceerror：错误绑定参数0 - 可能不支持类型。以下是我的代码：
class NewWindow(QtGui.QDialog):
def __init__(self, parent=None):
super(NewWindow, self).__init__(parent)
self.group1= QtGui.QGroupBox("Add Data")
self.patientName = QtGui.QLabel("Name")
self.patientEdit = QtGui.QLineEdit()
self.patientid = QtGui.QLabel("Id")
self.patientidEdit = QtGui.QLineEdit()
self.patientidEdit.setValidator(QtGui.QIntValidator(self.patientidEdit))
self.age = QtGui.QLabel("Age")
self.ageEdit = QtGui.QLineEdit()
self.ageEdit.setValidator(QtGui.QIntValidator(self.ageEdit))
self.genderlabel = QtGui.QLabel("Gender")
self.patientgend = QtGui.QLineEdit()
self.eyeType = QtGui.QLabel("Eye Type")
self.eyeTypeEdit = QtGui.QLineEdit()
self.AddData = QtGui.QPushButton("Add Data")
self.AddData.clicked.connect(self.AddData_clicked)
self.databaseLayout = QtGui.QGridLayout()
self.databaseLayout.addWidget(self.patientName,0,0)
self.databaseLayout.addWidget(self.patientEdit,0,1)
self.databaseLayout.addWidget(self.patientid,2,0)
self.databaseLayout.addWidget(self.patientidEdit,2,1)
self.databaseLayout.addWidget(self.age,4,0)
self.databaseLayout.addWidget(self.ageEdit,4,1)
self.databaseLayout.addWidget(self.genderlabel,6,0)
self.databaseLayout.addWidget(self.patientgend,6,1)
self.databaseLayout.addWidget(self.eyeType,8,0)
self.databaseLayout.addWidget(self.eyeTypeEdit,8,1)
self.databaseLayout.addWidget(self.AddData,10,10)
self.group1.setLayout(self.databaseLayout)
mainLayout = QtGui.QVBoxLayout()
mainLayout.addWidget(self.group1)
mainLayout.addStretch(1)
self.setLayout(mainLayout)
def AddData_clicked(self):
self.db_con = sqlite3.Connection
self.db_name = "./patientData.db"
self.createDb = sqlite3.connect(self.db_name)
self.queryCurs = self.createDb.cursor()
self.name = self.patientEdit.text()
self.id = self.patientidEdit.text()
self.age = self.ageEdit.text()
self.gender = self.patientgend.text()
self.eye_type = self.eyeTypeEdit.text()
self.queryCurs.execute('''CREATE TABLE IF NOT EXISTS PATIENT
(NAME TEXT NOT NULL, ID INTEGER PRIMARY KEY, AGE INTEGER NOT NULL, GENDER TEXT NOT NULL, EYE_TYPE TEXT NOT NULL)''')
self.queryCurs.execute('''INSERT INTO PATIENT(NAME, ID, AGE, GENDER, EYE_TYPE)
VALUES(?,?,?,?,?)''',(self.name,self.id,self.age,self.gender,self.eye_type))
print ('inserted row')
