BaseModelFormSet __init__() got an unexpected keyword argument

I am getting the above error when I have tried to convert my inline_formset to have at least the first row required. (please see here for the StackOverflow question) My existing code is below: ``` #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) ``` In order to customise the formset I defined the following: ``` class BaseFormSet(BaseModelFormSet): def __init__(self, *args, **kwargs): super(BaseFormSet, self).__init__(*args, **kwargs) for form in self.forms: form.empty_permitted = False ``` and pass use it as follows: ``` EducationInlineFormSet = inlineformset_factory(Applicant, Education, extra=1, can_delete=False, formset=BaseFormSet) ``` This returns the above error and having read around a lot I'm still none the wiser how I can keep passing an instance to the formset. Any help would be greatly appreciated. Regards, Chris.
