django - 將用戶標識添加到UpdateView

我有幾個使用ModelForms的UpdateView。每個對象都有一個用戶的外鍵，因此我可以將每個用戶的數據分開。當我嘗試在表單上更新數據，我得到：django - 將用戶標識添加到UpdateView

AttributeError的在/財務/交易/更新/ 4 「模塊」對象有沒有屬性「用戶」

創建對象的作品正好。這是更新給我的錯誤。

一個這樣的模型和視圖看起來是這樣的：

# Model 
class Transaction(models.Model): 
    item_description = models.CharField(max_length=255) 
    payment_type = models.CharField(max_length=1, choices=PAYMENT_CHOICES, verbose_name="Payment Type") 
    amount = models.DecimalField(max_digits=8, decimal_places=2, verbose_name="Estimated Amount") 
    actual_amount = models.DecimalField(max_digits=8, decimal_places=2, verbose_name="Actual Amount") 
    due_date = models.DateField(verbose_name="Due Date") 
    is_credit = models.BooleanField(verbose_name="Is Asset") 
    is_paid = models.BooleanField(verbose_name="Paid/Received?") 
    account = models.ForeignKey(Account) 
    user = models.ForeignKey(User) 

#ModelForm 
class TransactionForm(ModelForm): 
    class Meta: 
     model = Transaction 
     fields = ['is_paid', 'item_description', 'due_date', 'amount', 'actual_amount', 'is_credit', 'account',] 

#View 
class TransactionUpdate(UpdateView): 
    model = Transaction 
    form_class = TransactionForm 
    template_name = 'finances/transaction_update.html' 

    def __init__(self, **kwargs): 
     self.kwargs = kwargs 

    def form_valid(self, form): 
     transaction = form.save(commit=False) 
     transaction.user = self.request.user 
     transaction.save() 
     return super(TransactionUpdate, self).form_valid(form)

感謝，

我不認爲它的初始化屬性。嘗試更改__init__()方法 -

def __init__(self, **kwargs): 
    self.kwargs = kwargs 
    return super(TransactionUpdate, self).__init__(**kwargs)
