Question

我已经审查了数小时的许多问题/答案，并应用了许多技术，但是我无法将用户ID传递给 init （）方法的形式，它总是会出现诸如“ init （）收到了意外的关键字参数“ request””。有人知道原因吗？

表格，根据评论的要求进行了更新：

class ChildChoreForm(ModelForm):
  class Meta:
    model = ChildChore
    exclude = ('child',)
    fields = '__all__'

  def __init__(self, *args, **kwargs):
    self.request = kwargs.pop('request', None)
    super(ChildChoreForm, self).__init__(*args, **kwargs)
    self.fields['chore'].queryset = Chore.objects.filter(created_by=self.request.user)

ChildChoreFormSet = inlineformset_factory(Child,  ChildChore, form=ChildChoreForm, extra=1)

查看：

class ChildChoreUpdate(UpdateView):
  model = Child
  success_url = reverse_lazy('children-list') 
  form_class = ChildChoreFormSet

  def get_form_kwargs(self):
    kwargs = super().get_form_kwargs()
    if hasattr(self, 'object'):
        kwargs.update({'request': self.request})
    return kwargs

打开updaet网页后出现的错误：

问题是您已将表单设置为接受request中的__init__参数，但是您正在初始化 formset ，而不是 form < / em>。您需要将表单集修改为accept that same argument并将其传递给表单集中的表单：

# First define a base class that overrides __init__ and get_form_kwargs from django.forms import BaseFormSet class BaseChildChoreFormSet(BaseFormSet): def __init__(self, *args, **kwargs): # Handle the request argument that you are passing on init self.request = kwargs.pop('request', None) super().__init__(*args, **kwargs) def get_form_kwargs(self, index): kwargs = super().get_form_kwargs(index) # Add request to the kwargs that are passed to the form on init kwargs['request'] = self.request return kwargs # Now set up your formset using this class ChildChoreFormSet = inlineformset_factory( Child, ChildChore, form=ChildChoreForm, formset=BaseChildChoreFormSet, extra=1)

如何将用户ID从视图传递到Form的init方法？
