使用Model Form的Generic_inlineformset_factory创建表单

Question

我想用ModelForm来创建一个编辑表单。

我的模型之间有一种通用关系，所以如果有人能给我推荐一下视图和一些模板，我会非常感激，因为我对这门语言还很陌生。

我的模型大概是这样的：

 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,

如果有人能给我推荐一个链接之类的，那就太好了……

我来分享一下我找到的解决办法。在查看了Generic_inlineformset_factory的源代码后，我做了以下的视图：

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))

这个方法成功运行了。我觉得这对那些在模型中使用了通用关系，并想要创建一个表单来编辑这些信息的人会很有帮助。
