AttributeError: objet 'Ui_Dialog' n'a pas d'attribut 'lineEdit_3'

Question

Lien vers mon code complet: https://www.dropbox.com/s/0tdnm2yd8038fwh/additem.py?dl=0

Ceci est l'erreur que je reçois:

File "C:/Users/Lloyd/Desktop/Python Projects/stock/additem.py", line 187, in <module> 
    ui = Ui_Dialog() 
    File "C:/Users/Lloyd/Desktop/Python Projects/stock/additem.py", line 23, in __init__ 
    self.setupUi(self) 
    File "C:/Users/Lloyd/Desktop/Python Projects/stock/additem.py", line 66, in setupUi 
    self.buttonBox.accepted.connect(self.accept()) 
    File "C:/Users/Lloyd/Desktop/Python Projects/stock/additem.py", line 169, in accept 
    brandName = self.lineEdit_3.text() 
AttributeError: 'Ui_Dialog' object has no attribute 'lineEdit_3' 

Tout va bien avant d'ajouter:

self.buttonBox.accepted.connect(self.accept()) 

appel à cette méthode:

def accept(self): 
    conn = sqlite3.connect('inventory.db') 
    c = conn.cursor() 

    unix = time.time() 
    dateUpdated = datetime.datetime.fromtimestamp(unix).strftime('%Y-%m-%d %H:%M:%S') 
    company = self.lineEdit_2.text() 
    brandName = self.lineEdit_3.text() 
    genericName = self.lineEdit_4.text() 
    purchasePrice = self.lineEdit_5.text() 
    category = self.lineEdit_6.text() 
    sellingPrice = purchasePrice * sellingFactor 
    quantity = self.lineEdit_7.text() 
    #dosageForm = self.lineEdit_9.text() 
    expiryDate = self.lineEdit_10.text() 

    c.execute(
     "INSERT INTO inventory(dateUpdated, company, brandName, genericName, category, purchasePrice, sellingPrice, quantity, expiryDate) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)", 
     (dateUpdated, company, brandName, genericName, category, purchasePrice, sellingPrice, quantity, expiryDate)) 
    conn.commit() 

C'est le reste du code:

app = QtGui.QApplication(sys.argv) 
window = QtGui.QDialog() 

ui = Ui_Dialog() 
ui.setupUi(window) 

window.show() 
sys.exit(app.exec_())

Lorsque vous connectez un signal à un emplacement que vous devez transmettre au nom de la fente, la syntaxe est la suivante

sender.signal.connect(receiver.slot) 

Dans votre Si vous devez changer:

self.buttonBox.accepted.connect(self.accept()) 

à:

self.buttonBox.accepted.connect(self.accept) 

Remarque: Lorsque vous transmettez le nom d'emplacement PyQt, vous pouvez l'appeler, mais si vous transmettez la fonction évaluée, il est impossible de le faire.
