將自定義參數添加到django模型

Question

我有添加自定義參數到模型的麻煩（在這種情況下，來自request.user的當前用戶） 我曾經這樣做在以前的項目，我不能管理讓它在Django 1.10.4的新項目上工作。

我得到這個錯誤：

TypeError at /realestateprogram/edition_appartement/19/ 
__init__() got an unexpected keyword argument 'user' 

這是我的看法：

apartment = get_object_or_404(Apartment, pk=apartment_id) 
if request.method == 'POST': 
    form = ApartmentForm(request.POST, request.FILES, instance=apartment, user=request.user) 
    if form.is_valid(): 
     form.save() 
     return redirect('list_realestateprogram_apartment', realestateprogram_id=apartment.realestateprogram.id) 
    else: 
     print form.errors 
else: 
    form = ApartmentForm(instance=apartment, user=request.user) 

，這是我的形式：提前

class ApartmentForm(forms.ModelForm): 
    class Meta: 
     model = Apartment 
     exclude = ('realestateprogram',) 

    def __init__(self, *args, **kwargs): 
     self.user = kwargs.pop('user') 
     super(ApartmentForm, self).__init__(*args, **kwargs) 

感謝，如果你能幫助我

嘗試通過所有值與關鍵字參數：

form = ApartmentForm(data=request.POST, files=request.FILES, instance=apartment, user=request.user) 

如果你看一下class based generic views，這就是他們如何做到這一點。我還建議你看看Form handling with class-based views。
