我正在运行python 2.7.8版本。我将项目标题存储在sqlite数据库中，尝试将它们导入到组合框中。当我尝试从sqlite数据库中导入项目标题并将它们导入到组合框中时，我收到以下错误：TypeError: 'unicode' object is not callable
以下是我的代码：
main.py
main.py
from EvDB import EvDB
import wx
from ProjectsPanel import ProjectsPanel
class MyFrame(wx.Frame):
""" We simply derive a new class of Frame. """
def __init__(self, parent, ID, title):
wx.Frame.__init__(self, parent, ID, title=title, size=(650,725))
# Create Database Tables
self.db = EvDB(self)
self.db.createTbls()
main = wx.Panel(self)
self.projectsPg = ProjectsPanel(main, -1)
self.mainSizer = wx.BoxSizer(wx.VERTICAL)
self.mainSizer.Add(self.projectsPg, 1, wx.ALL|wx.EXPAND)
main.SetAutoLayout(True)
main.SetSizer(self.mainSizer)
self.mainSizer.Fit(main)
self.Layout()
self.Show()
self.UserID = 1
rows = self.db.getProjects(self.UserID)
print(rows)
print(str(rows))
self.projectsPg.cb.Value(rows)
app = wx.App(False)
ProjectsPanel.py
import wx
from EvDB import EvDB
import sqlite3 as lite
class ProjectsPanel(wx.Panel):
def __init__(self, parent, ID):
wx.Panel.__init__(self, parent, ID)
self.db = lite.connect('evDB.db')
self.cur = self.db.cursor()
self.db2 = EvDB(self)
sizer = wx.BoxSizer(wx.VERTICAL)
# the combobox Control
self.userProjects = ['Before1','Before2', 'Before3', 'Before4']
self.cb = wx.ComboBox(self, value='New', choices=self.userProjects, style=wx.CB_DROPDOWN)
sizer.Add(self.cb, 0, wx.EXPAND)
# Setting Layouts
self.SetAutoLayout(True)
self.SetSizer(sizer)
sizer.Fit(self)
EvDB.py
import sqlite3 as lite
class EvDB():
def __init__(self, parent):
self.db = lite.connect('evDB.db')
self.cur = self.db.cursor()
def createTbls(self):
self.db.execute('''CREATE TABLE IF NOT EXISTS Projects
(ID INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
Title varchar(50) DEFAULT NULL,
DateCreated DATE);''')
self.db.execute('''CREATE TABLE IF NOT EXISTS User_x_Project
(ID INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
UserID INT DEFAULT NULL,
ProjectID INT DEFAULT NULL);''')
def getProjects(self,userID):
self.cur.execute("SELECT Title FROM User_x_Project, Projects WHERE User_x_Project.UserID = "+str(userID)+" AND User_x_Project.ProjectID = Projects.ID;")
rows = self.cur.fetchall()
return rows
输出结果为：[(u'Tests',), (u'Test1',), (u'Test2',), (u'Test3',)]
我如何将存储在sqlite数据库中的标题添加到我的组合框中？
非常感谢您的所有帮助！
