BaseModelFormSet __init __（）得到了一个意外的关键字参数

Question

当我尝试将我的inline_formset转换为至少需要第一行时，我收到了上述错误。 (please see here for the StackOverflow question)

我现有的代码如下：

#views.py
def application(request, job_id):
    job = get_object_or_404(Job, pk=job_id)
    #return 404 if job isn't yet published
    if (job.pub_date>timezone.now() or job.close_date<timezone.now()):
        return HttpResponseNotFound('<h1>Job not found</h1>')

    #create all the inlineformsets (can_delete) set to false as will always be empty upon population
    EducationInlineFormSet = inlineformset_factory(Applicant, Education, extra=1, can_delete=False)
    QualificationInlineFormSet = inlineformset_factory(Applicant, Qualification, extra=1, can_delete=False)
    EmploymentInlineFormSet = inlineformset_factory(Applicant, Employment, extra=1, can_delete=False)

    if request.method == 'POST':
        applicant = Applicant(job=job)
        form = ApplicantForm(request.POST, instance=applicant)
        bottom_form = ApplicantFormBottom(request.POST, instance=applicant)
        education_formset = EducationInlineFormSet(request.POST, instance=applicant)
        qualification_formset = QualificationInlineFormSet(request.POST, instance=applicant)
        employment_formset = EmploymentInlineFormSet(request.POST, instance=applicant)

        #check all of the forms and formsets are valid
        if form.is_valid() and bottom_form.is_valid() and education_formset.is_valid() and qualification_formset.is_valid() and employment_formset.is_valid():
            # save the model to database, directly from the form:
            form.save()
            bottom_form.save()
            education_formset.save()
            qualification_formset.save()
            employment_formset.save()
            return render(request, 'jobs/success.html')


    else:
        applicant = Applicant(job=job)
        form = ApplicantForm(instance=applicant)
        bottom_form = ApplicantFormBottom(instance=applicant)
        education_formset = EducationInlineFormSet(instance=applicant)
        qualification_formset = QualificationInlineFormSet(instance=applicant)
        employment_formset = EmploymentInlineFormSet(instance=applicant)


    c = { 
    'job' : job,
    'form' : form ,
    'bottom_form' : bottom_form,
    'education_formset' : education_formset,
    'qualification_formset' : qualification_formset,
    'employment_formset' : employment_formset,
    }
    return render(request, 'jobs/application.html', c)

为了自定义formset，我定义了以下内容：

class BaseFormSet(BaseModelFormSet):
    def __init__(self, *args, **kwargs):
        super(BaseFormSet, self).__init__(*args, **kwargs)
        for form in self.forms:
            form.empty_permitted = False

并通过如下使用：

EducationInlineFormSet = inlineformset_factory(Applicant, Education, extra=1, can_delete=False, formset=BaseFormSet)

这会返回上面的错误并且阅读了很多内容我仍然不知道如何将实例传递给formset。

非常感谢任何帮助。

此致

克里斯。

我有一个类似的问题 - 问题是自定义的formset。

尝试从BaseInlineFormSet（不是BaseModelFormSet）进行子类化。

以下是the docs的相关部分。
