python - BaseModelFormSet __init__() got an unexpected keyword argument -

i getting above error when have tried convert inline_formset have @ least first row required. (please see here stackoverflow question)

my existing code 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 inlineformsets (can_delete) set false 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 of forms , formsets valid         if form.is_valid() , bottom_form.is_valid() , education_formset.is_valid() , qualification_formset.is_valid() , employment_formset.is_valid():             # save model database, directly 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 customise formset defined following:

class baseformset(basemodelformset):     def __init__(self, *args, **kwargs):         super(baseformset, self).__init__(*args, **kwargs)         form in self.forms:             form.empty_permitted = false 

and pass use follows:

educationinlineformset = inlineformset_factory(applicant, education, extra=1, can_delete=false, formset=baseformset) 

this returns above error , having read around lot i'm still none wiser how can keep passing instance formset.

any appreciated.

chris.

i had similar issue - problem customised formset.

try subclassing baseinlineformset (not basemodelformset).
