将tkinter条目数据提交到sqlite3 db

Question

在这里完成菜鸟操作，我正在尝试将一组tkinter输入框中的数据提交给sqlite3。 当我运行代码时，窗体正确显示并创建了表，但是数据没有提交到数据库。 我收到一条错误消息，指出未定义“ submit_record”（连接到提交按钮的函数）。 我已经尝试了所有我知道的或可以在网上找到的东西。 如果可以的话请帮忙。 在这件事上苦苦挣扎了2个星期！ 谢谢。

    self.conn = sqlite3.connect('cacfp_test.db')
    # Create a cursor

    # Create the table if it doesn't exist
    try:

Answer 1

您的代码中有更多的不一致之处。

首先，当您在staff_dtls中staff_dtls例如self.lname_entry.get() ，您必须定义self.lname_entry ，但由于Python类和OOP理论 ，仅拥有lname_entry是不够的。

接下来，变量名称有些混乱，例如在staff_dtls具有self.inc_type.get() ，但必须具有self.inc_type_entry.get() ，反之亦然，例如， ue_tax = ttk.Entry(box2, textvariable=ue_tax_entry_value) ，但您需要ue_tax_entry = ttk.Entry(box2, textvariable=ue_tax_entry_value) 。 因此，精确地统一您的变量名。

接下来，您需要类似self.c.execute("INSERT INTO staffing VALUES (?, ?, ?, ?, ?, ?, ...)", (element)) c.excecute("INSERT INTO staffing VALUES (?)", (element)) ，而不是c.excecute("INSERT INTO staffing VALUES (?)", (element)) （带有错字执行） self.c.execute("INSERT INTO staffing VALUES (?, ?, ?, ?, ?, ?, ...)", (element)) ，带有这么多的问号，要插入到数据库中的列数。

这些是修复时的主要错误，您将走在正确的轨道上。
