django：クラスベースのフォームにはエラーはありませんが、無効です。何が起こっている？

Question

.is_valid()からFalseを返すフォームがありますが、.errorsと.non_field_errors()は空に見えます。これを引き起こしている可能性があることを確認する他の方法はありますか？

場合、それは私のログコードの問題だ、ここにある：

logger.debug('form.non_field_errors(): ' + str(form.non_field_errors())) 
logger.debug('form.errors: ' + str(form.errors)) 

マイフォームコード：

class IncorporateForm(forms.Form): 
     type_choices = (("LTD", "Private company limited by shares"), 
         ("LTG", "Private company limited by guarantee"), 
         ("PLC", "Public limited company"), 
         ("USC", "Unlimited company with share capital"), 
         ("UWS", "Unlimited company without share capital")) 

     country_choices = (("EW", "England and Wales"), 
          ("CY", "Wales"), 
          ("SC", "Scotland"), 
          ("NI", "Northern Ireland")) 

     articles_choices = (("MOD", "Model articles"), 
          ("AMD", "Model articles with amendments"), 
          ("BES", "Entirely bespoke articles")) 

     name = forms.CharField(initial = "[name] limited") 

     registered_office = forms.CharField(widget=forms.Textarea, 
              label='Registered office address') 

     registration_country = forms.ChoiceField(choices=country_choices, 
               widget=forms.RadioSelect(renderer=SaneRadioField)) 

     company_type = forms.ChoiceField(choices=type_choices, 
             widget=forms.RadioSelect(renderer=SaneRadioField), initial="LTD") 

     articles_type = forms.ChoiceField(choices=articles_choices, 
              initial='MOD', 
              widget=forms.RadioSelect(renderer=SaneRadioField)) 

     restricted_articles = forms.BooleanField() 

     arts_upload = forms.FileField(label='Articles to upload') 

マイビューコード（私はフォームがあることを検出地点へ無効）：

def incorporate_view(request): 
     form = IncorporateForm() 
     DirectorsFormset = forms.formsets.formset_factory(OfficerForm, extra=30) 
     CapitalFormset = forms.formsets.formset_factory(CapitalForm, extra=30) 
     HoldingFormset = forms.formsets.formset_factory(HoldingForm, extra=30) 
     AmendsFormset = forms.formsets.formset_factory(ArticlesAmendsForm, extra=50) 

     if request.method == 'POST': 
       #bind and validate 
       form.data = request.POST 
       guarantee_form = GuaranteeForm(data=request.POST) 
       directors_formset = DirectorsFormset(prefix='directors', data=request.POST) 
       capital_formset = CapitalFormset(prefix='capital', data=request.POST) 
       holding_formset = HoldingFormset(prefix='holding', data=request.POST) 
       amends_formset = AmendsFormset(prefix='amends', data=request.POST) 
       save_objects = [] # objects to be saved at the end if there is no error 
       user_objects = {} # keyed by email 
       individual_objects = {} # keyed by email? 

       if(not (form.is_valid() and guarantee_form.is_valid() 
         and directors_formset.is_valid() 
         and capital_formset.is_valid() and 
         holding_formset.is_valid() and 
         amends_formset.is_valid())): 
         dbg_str = """ 
         form.is_valid(): %s 
         guarantee_form.is_valid(): %s 
         directors_formset.is_valid(): %s 
         capital_formset.is_valid(): %s 
         holding_formset.is_valid(): %s 
         amends_formset.is_valid(): %s 
         """ % (form.is_valid(), guarantee_form.is_valid(), 
           directors_formset.is_valid(), 
           capital_formset.is_valid(), 
           holding_formset.is_valid(), 
           amends_formset.is_valid()) 
         logger.debug(dbg_str) 
         logger.debug('form.non_field_errors(): ' + str(form.non_field_errors())) 
         logger.debug('form.errors: ' + str(form.errors))

form.dataに割り当てると、フォームをバインドしません。オブジェクトが構築されたときのdict（またはコードを調べてどのフラグが設定されているかを確認しますが、これはおそらく文書化されていないため推奨されません）。
