djangomultimodelform с Inlineform, используя пакет django -multform

Question

У меня проблема с обработкой Updateview в django. Мой дизайн содержит 2 модели и один Inlineformset. Это представление будет добавлено с большим количеством моделей и наборов inlineform, если это работает.

Мой createview работает нормально. Но Updateview выдает прикрепленную ошибку error image . 1) Любая идея, почему это вызывает. 2) Любой лучший способ обрабатывать несколько форм и несколько строк вместе для операций CRUD

Формы

class CompanyManagementForm(forms.ModelForm):    
entitynamepreferred=forms.CharField(max_length=200, required=False, label='COMPANY Name (Optional):')
clientcategory=forms.ModelChoiceField(keyword.objects.filter(keywordtype = 'CLIENT_CATEGORY'), required=False) 
class Meta:
    model=EntityList
    fields =('entitynamepreferred', 'clientcategory')
    labels ={'entitynamepreferred' : 'COMPANY Name (Preferred):', 
    'clientcategory': ' Client category', 
    widgets = {
    'entitynamepreferred': forms.TextInput(attrs={'class':'form-control'}),  } 

def __init__(self, * args, **kwargs):
    super().__init__(*args, **kwargs)
    self.helper = FormHelper()
    self.helper.form_class = 'form-horizontal'
    self.helper.label_class = 'col-lg-4'
    self.helper.field_class = 'col-lg-8'
    self.helper.layout = Layout(
        Fieldset(
            'first arg is the legend of the fieldset',
            'entitynamepreferred', 'clientcategory' ))

class TransactionProfileform(forms.ModelForm):  # this has a relationship with CompanyManagementmodel above
class Meta:
    model=TransactionProfile
    fields =('sourceoffund', 'sourcedetaileddescription', 'expectedtransactioninentity1')

def __init__(self, * args, **kwargs):
    super().__init__(*args, **kwargs)
    self.helper = FormHelper()
    self.helper.form_class = 'form-horizontal'
    self.helper.label_class = 'col-lg-4'

    self.helper.layout = Layout(
        Fieldset(
            'first arg is the legend of the fieldset',
            'sourceoffund', 'sourcedetaileddescription', 'expectedtransactioninentity1'        ))

class Roleform(forms.ModelForm):
class Meta:
    model=Roles
    fields = ('personrole', 'personname')
    exclude = ()     
Rolesformset = inlineformset_factory(EntityList, Roles, form= Roleform, fields = ('personrole', 'personname'), extra=1)

class CompanyManagementMultiform(MultiModelForm):  # its a multimodelfrom from django-multiform and not from better form packages
base_forms = {
    'CompanyManagement': CompanyManagementForm,
    'TransactionProfile': TransactionProfileform,           
}

Мой createview прекрасно работает там, где есть updateview не работает.
