用python/tkinter/sqlite保存按鈕

Question

我有一個tkinter框架頁面，它有文本框輸入客戶詳細信息的名稱和地址。同一頁面還有一個保存按鈕，該按鈕鏈接到另一個將文本框中的詳細信息保存到.sqlite數據庫的方法。然而，當我點擊按鈕它說「sqlite3.InterfaceError：錯誤綁定參數1 - 可能不支持的類型。」 非常明顯的錯誤，但我不知道將輸入更改爲正確的輸入。請，任何幫助將是驚人的，謝謝！

代號爲TK幀間和頁面佈局+保存按鈕：

import tkinter as tk 
import sqlite3 

class Page(tk.Frame): 
    def __init__(self, *args, **kwargs): 
     tk.Frame.__init__(self, *args, **kwargs) 
    def show(self): 
     self.lift() 

class Page1(Page): 

    fName = "" 
    sName = "" 
    address1 = "" 
    address2 = "" 
    city = "" 
    postCode = "" 

    def __init__(self, *args, **kwargs): 
     tk.Frame.__init__(self, *args, **kwargs) 

     #Set up labels 
     spaceLabel = tk.Label(self, text="") 
     fNameLabel = tk.Label(self, text="First Name: ") 
     sNameLabel = tk.Label(self, text="Last Name: ") 
     address1Label = tk.Label(self, text="Address Line 1: ") 
     cityLabel = tk.Label(self, text="City: ") 
     postCodeLabel = tk.Label(self, text="Post Code: ") 

     #Create string variables 
     self.fName = tk.StringVar() 
     self.sName = tk.StringVar() 
     self.address1 = tk.StringVar() 
     self.address2 = tk.StringVar() 
     self.city = tk.StringVar() 
     self.postCode = tk.StringVar() 

     #Set up text entry boxes 
     fNameBox = tk.Entry(self, textvariable = self.fName) 
     sNameBox = tk.Entry(self, textvariable = self.sName) 
     address1Box = tk.Entry(self, textvariable = self.address1) 
     address2Box = tk.Entry(self, textvariable = self.address2) 
     cityBox = tk.Entry(self, textvariable = self.city) 
     postCodeBox = tk.Entry(self, textvariable = self.postCode) 

     #Arrange Labels 
     spaceLabel.grid(row=0, column=0) 
     fNameLabel.grid(row=1, column=0, padx = 10, pady = 10) 
     sNameLabel.grid(row=1, column=2, padx = 10, pady = 10) 
     address1Label.grid(row=2, column=0, padx = 10, pady = 10) 
     address2Label.grid(row=3, column=0, padx = 10, pady = 10) 
     cityLabel.grid(row=4, column=0, padx = 10, pady = 10) 
     postCodeLabel.grid(row=5, column=0, padx = 10, pady = 10) 

     #Arrange text entry boxes 
     fNameBox.grid(row=1, column=1, padx = 10, pady = 10) 
     sNameBox.grid(row=1, column=3, padx = 10, pady = 10) 
     address1Box.grid(row=2, column=1, padx = 10, pady = 10) 
     address2Box.grid(row=3, column=1, padx = 10, pady = 10) 
     cityBox.grid(row=4, column=1, padx = 10, pady = 10) 
     postCodeBox.grid(row=5, column=1, padx = 10, pady = 10) 

     #Save Details button 
     saveCustomerDetails = tk.Button(self, text = "Save Details", command = self.SaveDetails) 
     saveCustomerDetails.pack() 
     saveCustomerDetails.grid(row=6,column=2,padx = 20, pady = 20) 

    #When you click one save button, it should use this method to add the data 
    # entry field text to the database. 

    def SaveDetails(self): 
     conn = sqlite3.connect('lanyard.db') 
     c = conn.cursor() 
     c.execute('PRAGMA foreign_keys = ON') 
     conn.commit() 

     customerData = [(None, self.fName, self.sName, self.address1, self.address2, self.city, self.postCode)] 

     for element in customerData: 
      c.execute("INSERT INTO Customers VALUES (?,?,?,?,?,?,?)", element) 
     conn.commit() 

     c.close() 
     conn.close() 

     fNameBox.delete(0, END) 
     sNameBox.delete(0, END) 
     address1Box.delete(0, END) 
     address2Box.delete(0, END) 
     cityBox.delete(0, END) 
     postCodeBox.delete(0, END) 

     print ("Saved") 

SQLite數據庫的建立如下：

import sqlite3 
conn = sqlite3.connect('lanyard.sqlite') 
cursor = conn.cursor() 

#Customers 
cursor.execute('''DROP TABLE IF EXISTS Archive''') 
cursor.execute('''CREATE TABLE IF NOT EXISTS Customers(
       Customer_Id INTEGER PRIMARY KEY, 
       First_Name TEXT(20), 
       Last_Name TEXT(20), 
       Address_1 TEXT(20), 
       Address_2 TEXT(20), 
       City TEXT(20), 
       Post_Code TEXT(20))''') 

cursor.execute('''PRAGMA foreign_keys = ON''') 

cursor.close() 
conn.commit() 
conn.close()

源碼不知道什麼StringVar是 - 你必須通過它正常值。嘗試改變你的customerData名單像這樣：

customerData = [(None, self.fName.get(), self.sName.get(), 
       self.address1.get(), self.address2.get(), 
       self.city.get(), self.postCode.get())]
