Remembered收到了意外的关键字参数“ pk”

如何解决Remembered收到了意外的关键字参数“ pk”

我试图通过单击按钮来增加值。但是我得到了错误

remembered() got an unexpected keyword argument 'pk'

我不了解，因为据我所知，函数Remembered（）需要同时发送两个PK。

网址

 path('mypage/<int:pk>/',DeckDetailView.as_view(),name='mypage-study-deck'),path('mypage/<int:pk>/<int:card_id>',views.remembered,name='remembered')

        context = super(DeckDetailView,self).get_context_data(*args,**kwargs)
        context['cards'] = Card.objects.filter(
            decks__title=deck_title).filter(days_till_study=1)
        return context

    if request.method == 'POST':
        deck = get_object_or_404(Deck,pk=deck_id)
        card = get_object_or_404(Card,pk=card_id)
        card.days_till_study = card.days_till_study * 2
        card.save()
        return redirect('/mypage/' + str(deck.id))

解决方法

您在此处通过网址传递pk和card_id。但是鉴于您没有考虑传递数据的顺序。因此，让我们尝试一下。

def remembered(request,pk,card_id):
    if request.method == 'POST':
        deck = get_object_or_404(Deck,pk=pk)
        card = get_object_or_404(Card,pk=card_id)
        card.days_till_study = card.days_till_study * 2
        card.save()
        return redirect('/mypage/' + str(deck.id))
