Django 如何将用户id从视图传递到表单'；s初始化方法？

我已经复习了很多问题/答案好几个小时，并应用了很多技巧，但我无法将用户id传递给表单init（）方法，它总是会出现类似“init（）得到意外的关键字参数“request”这样的错误。有人知道原因吗

根据评论中的要求更新的表格：

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)

视图：

打开updaet网页后出现的错误：

问题是，您已将表单设置为接受

\uuuu init\uuuu

中的

请求

参数，但您正在初始化表单集，而不是表单。您需要将表单集修改为，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)

您可以发布错误的完整堆栈跟踪吗？同时向我们显示您定义

ChildChoreFormSet

的代码，因为这是最有可能出现问题的地方。您正在将一个

请求

参数传递给表单集构造函数，而不是表单构造函数。请根据请求进行更新，谢谢高级。您使用的是自定义表单还是基于django模型的表单？它是基于模型的表单。。。我有一个用于填充/更新子数据的表单，在该表单下有一个用于家务的表单集，其中有一个标题和其他字段，但标题是由不同用户创建的下拉列表。因此，我想根据当前用户（父亲/母亲）对其进行过滤。除此之外，我想知道为什么我不能将请求传递给表单集，因为我可能会出于不同的目的使用相同的解决方案。

# 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)
