bir satır ekleme çalışmıyor ListStore için - saçma istisna

Question

İlk kod:

from gi.repository import Gtk, GtkSource, GObject 

import os.path 
import shelve 

class MusicCollection(object): 

    def __init__(self): 
     self.builder = Gtk.Builder()

     GObject.type_register(GtkSource.View) 
     self.builder.add_from_file(self.glade_file) 
     self.window = self.builder.get_object("window1") 
     self.entry_author = self.builder.get_object("entry_author") 
     self.entry_album = self.builder.get_object("entry_album")

    def initialize(self): 
     try: 
      self.albums = self.db['albums'] 
     except KeyError: 
      self.db["albums"] = [] 
      self.db.sync() 

     self.albums = self.db['albums'] 

     for i in range(len(self.albums)): 
      self.albums_list.append(self.albums[i]) 

     for i in range(len(self.columns)):

Ben ListStore nesne üzerinde .Append() yapsak böyle hata alıyorum: Elbette

Traceback (most recent call last): 
    File "./music.py", line 85, in create 
    self.albums_list.append(new_entry) 
    File "/usr/lib/python3/dist-packages/gi/overrides/Gtk.py", line 945, in append 
    return self._do_insert(-1, row) 
    File "/usr/lib/python3/dist-packages/gi/overrides/Gtk.py", line 936, in _do_insert 
    row, columns = self._convert_row(row)

    self.init(value_type)

ListStore nesnesi (str, str, str, boole) türüdür. Hata mesajı saçma, neler olduğunu anlatabilir mi?

Answer 1

Sorun, sütun türlerini tanımlarken, GTK olanlar yerine python türü adları kullanmıştım. Bunu (str, str, str, bool) olarak ayarladım, ancak (gchararray, gchararray, gchararray, gboolean) olmalıdır.
