问题描述
我有一个 tkinter 框架页面,其中包含用于输入客户详细信息的姓名和地址的文本框.同一页面还有一个保存按钮,该按钮链接到另一种方法,该方法将文本框中的详细信息保存到 .sqlite 数据库.但是,当我单击该按钮时,它会显示sqlite3.InterfaceError:错误绑定参数 1 - 可能不受支持的类型".一个不言自明的错误,但我不知道将输入更改为正确的.拜托,任何帮助都会很棒,谢谢!
I have a tkinter frame page which has text boxes to type in name and address for customer details. The same page also has a save button that is linked to another method that saves the details in the text boxes to an .sqlite database. However when I click the button it says "sqlite3.InterfaceError: Error binding parameter 1 - probably unsupported type."Quite a self explanatory error but I have no idea to change the input to the right one. Please, any help will be amazing, thanks!
tk 帧间和页面布局的代码 + 保存按钮:
Code for the tk inter frame and page layout + save button:
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 数据库创建如下:
SQLite database is created as follows:
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()
推荐答案
sqlite 不知道 StringVar
是什么——你必须向它传递正常值.尝试像这样更改您的 customerData
列表:
sqlite has no idea what StringVar
is -- you must pass it normal values. Try changing your customerData
list like so:
customerData = [(None, self.fName.get(), self.sName.get(),
self.address1.get(), self.address2.get(),
self.city.get(), self.postCode.get())]
