Question

我试图按照this link中的说明将用户（即request.user）传递给我的模型构造函数。但是我得到了

TypeError: __init__() got an unexpected keyword argument 'us'

错误。这是我的观点

class dealAdd(generic.CreateView):
    form_class = dealForm
    template_name='deals/deal_Add.html'

    def get_context_data(self,**kwargs):
        context=super(dealAdd,self).get_context_data(**kwargs)
        llist=lead.objects.all()
        clist=contacts.objects.all()
        context.update({'leadob':llist,'contob':clist})
        return context

    def get_form_kwargs(self, *args, **kwargs):
        kwargs = super(dealAdd, self).get_form_kwargs()
        kwargs.update({'us': self.request.user})
        return kwargs

和我的表单构造器

def __init__(self,*args,**kwargs):
       usr=kwargs.pop('us')
       super(dealForm,self).__init__(*args, **kwargs)
       print(usr)
      # print(self)

回溯说我有错误

context=super(dealAdd,self).get_context_data(**kwargs)

所以我认为有问题吗？

跟踪：

我的表格

class dealForm(forms.ModelForm):
    class Meta:
        model=deals
        fields= '__all__'
        widgets={
        'refno':forms.TextInput(attrs={'class':'input-sm form- 
         control ember-view ember-text-field'}),
        'status':forms.Select(choices=stat,attrs={'class':'btn btn-deals'}),

Answer 1

也许是因为订单。

您在get_context_data之前先进行get_form_kwargs的CreateView调用。这意味着它会在更新之前“弹出”您的“我们”。

只需更改usr=kwargs.pop('us', None)即可避免错误，或使用try/except。

无法从Django createview调用表单构造函数
