I am running python version 2.7.8. I am storing project titles in a sqlite database that I am trying to import into a combobox. When I try and import the project titles from the sqlite database and import them into the combobox I get this error: TypeError: 'unicode' object is not callable
Here is my code:
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
the print results: [(u'Tests',), (u'Test1',), (u'Test2',), (u'Test3',)]
How do I add the titles stored in my sqlite database to my combobox?
Thank you for any and all help!
EDIT: Here is my entire traceback
C:\Python27\python.exe C:/Users/xxx/xxx/xxx/main.py

TypeError: 'unicode' object is not callable
Process finished with exit code 1
self.projectsPg.cb
is a ComboBox object, and Value
is a property. If you access the property without assignment it will return a string (or unicode). You can't call it.
If you want to set a value to the combox, use property assignment (ComboBox.Value =
), or ComboxBox.SetValue
:
In addition to that, the rows
returned by Cursor.fetchall
is a list of tuples. You need to fetch the first one. (In the following example, I omitted return row count check for brevity)
self.projectsPg.cb.Value = rows[0][0]
# OR
self.projectsPg.cb.SetValue(rows[0][0])
