无法从我的数据库中为我的 tkinter GUI 检索数据

Question

它不允许我从我的数据库中访问我的提示，出现错误。

代码：

def do_question(self):
self.func1()
#myGlobal + 1
if myGlobal >5:
    import MathsvadersReal

SQL = 'SELECT * FROM tblQuestion'
cursor = Databaseconnector.SELECT(SQL)
rows = cursor.fetchall()
random_row = random.choice(rows)

print random_row.QuestionID, random_row.Question, random_row.Hint, random_row.A1, random_row.A2, random_row.A3, random_row.A4, random_row.CorrectAnswer

# create welcome label
self.label1 = Tkinter.Label(self, bg ='yellow', text = (random_row.Question))
self.label1.grid(row = 0, column = 6, columnspan = 2, sticky = 'E')

self.label111 = Tkinter.Label(self, bg ='red', text = (random_row.QuestionID))
self.label111.grid(row = 0, column = 1, columnspan = 4, sticky = 'W')

提示代码：

  def homepage_link(self):
    SQL = 'SELECT Hint FROM tblQuestion WHERE QuestionID = %s' % self.label111
    cursor = Databaseconnector.SELECT(SQL)
    rows = cursor.fetchall()
    tkMessageBox.showinfo("Hint", rows[0]['Hint'])

错误：

IndexError: 列表索引超出范围

Answer 1

您传递的是小部件的字符串表示形式，而不是 text 选项。 homepage_link 的第一行应该是：

SQL = 'SELECT Hint FROM tblQuestion WHERE QuestionID = %s' % self.label111['text']
