Creating a form using Generic_inlineformset_factory from a model form

Question

I wanted to create an edit form using ModelForm.

and my models contain common relationship b / w classes, so if someone can offer me a presentation and some templates for this purpose, I would be very grateful as I am new to the language.

My models look like this: -

class Employee(Person): nickname = models.CharField(_('nickname'), max_length=25, null=True, blank=True) blood_type = models.CharField(_('blood group'), max_length=3, null=True, blank=True, choices=BLOOD_TYPE_CHOICES) marital_status = models.CharField(_('marital status'), max_length=1, null=True, blank=True, choices=MARITAL_STATUS_CHOICES) nationality = CountryField(_('nationality'), default='IN', null=True, blank=True) about = models.TextField(_('about'), blank=True, null=True) dependent = models.ManyToManyField(Dependent, through='DependentRelationship') pan_card_number = models.CharField(_('PAN card number'), max_length=50, blank=True, null=True) policy_number = models.CharField(_('policy number'), max_length=50, null=True, blank=True) # code specific details user = models.OneToOneField(User, blank=True, null=True, verbose_name=_('user')) class Person(models.Model): """Person model""" title = models.CharField(_('title'), max_length=20, null=True, blank=True) first_name = models.CharField(_('first name'), max_length=100) middle_name = models.CharField(_('middle name'), max_length=100, null=True, blank=True) last_name = models.CharField(_('last name'), max_length=100, null=True, blank=True) suffix = models.CharField(_('suffix'), max_length=20, null=True, blank=True) slug = models.SlugField(_('slug'), max_length=50, unique=True) class PhoneNumber(models.Model) : phone_number = generic.GenericRelation('PhoneNumber') email_address = generic.GenericRelation('EmailAddress') address = generic.GenericRelation('Address') date_of_birth = models.DateField(_('date of birth'), null=True, blank=True) gender = models.CharField(_('gender'), max_length=1, null=True, blank=True, choices=GENDER_CHOICES) content_type = models.ForeignKey(ContentType, 

If anyone can offer me a link or so. that would be a big help ........

publication of the solution found. Looking at the source Generic_inlineformset_factory.

I made my opinion as: -

 def edit_contact(request): c={} profile = request.user.get_profile() EmployeeFormSet = generic_inlineformset_factory(PhoneNumber,extra=0,can_delete=False) EmployeeFormSet1=generic_inlineformset_factory(EmailAddress,extra=0,can_delete=False) EmployeeFormSet2 = generic_inlineformset_factory(Address, extra = 0, can_delete=False) if request.method == "POST": p_formset = EmployeeFormSet(data=request.POST, instance = profile), e_formset = EmployeeFormSet1(data=request.POST, instance = profile), a_formset = EmployeeFormSet2(data=request.POST, instance = profile), for e in p_formset: if e.is_valid(): e.save() for e in e_formset: if e.is_valid(): e.save() for e in a_formset: if e.is_valid(): e.save() return HttpResponseRedirect('/forms/sucess-edit/') else: p_formset = EmployeeFormSet(instance = profile), e_formset = EmployeeFormSet1(instance = profile), a_formset = EmployeeFormSet2(instance = profile), c.update({'p_formset': p_formset, 'e_formset': e_formset,'a_formset': a_formset}) return render_to_response('forms/edit_contact.html',c, context_instance=RequestContext(request)) 

This worked successfully, I think it will be a good help if someone uses Generic Relation in their model and wants to create a form for editing this information.
