將tkinter條目數據提交到sqlite3 db

Question

在這里完成菜鳥操作，我正在嘗試將一組tkinter輸入框中的數據提交給sqlite3。 當我運行代碼時，窗體正確顯示並創建了表，但是數據沒有提交到數據庫。 我收到一條錯誤消息，指出未定義“ submit_record”（連接到提交按鈕的函數）。 我已經嘗試了所有我知道的或可以在網上找到的東西。 如果可以的話請幫忙。 在這件事上苦苦掙扎了2個星期！ 謝謝。

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

    # Create the table if it doesn't exist
    try:
      self.c.execute("CREATE TABLE if not exists Staffing(ID INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, lname TEXT NOT NULL, fname TEXT NOT NULL, title TEXT NOT NULL, department TEXT NOT NULL, payType TEXT NOT NULL, start INTEGER NOT NULL, end_dt INTEGER NOT NULL, t_hours INTEGER NOT NULL, perinc REAL NOT NULL, inc_type TEXT NOT NULL, inc_date INTEGER NOT NULL, hrs_month INTEGER NOT NULL, month_yr INTEGER NOT NULL, c_hours REAL NOT NULL, per_c_hours REAL NOT NULL, gross_hrly REAL NOT NULL, gross_hrly_entry REAL NOT NULL, emp_tax REAL NOT NULL, ue_tax REAL NOT NULL, total_tax REAL NOT NULL, cost_per_emp REAL NOT NULL, cost_total TEXT NOT NULL);")

Answer 1

您的代碼中有更多的不一致之處。

首先，當您在staff_dtls中staff_dtls例如self.lname_entry.get() ，您必須定義self.lname_entry ，但由於Python類和OOP理論 ，僅擁有lname_entry是不夠的。

接下來，變量名稱有些混亂，例如在staff_dtls具有self.inc_type.get() ，但必須具有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，精確地統一您的變量名。

接下來，您需要類似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)) （帶有錯字執行） self.c.execute("INSERT INTO staffing VALUES (?, ?, ?, ?, ?, ?, ...)", (element)) ，帶有這么多的問號，要插入到數據庫中的列數。

這些是修復時的主要錯誤，您將走在正確的軌道上。
