无法在django formset中获取表单值

Question

我想要在formset中获取特定表单的结果。我尝试过一个没有成功的formset和modelformset。

有了一个formset

我的看法是这样的：

def display(request, pk=None, action='add'): 
    customer = get_customer(request)   
    qs = CustomerActivity.objects.filter(customer=customer) 


    AuthorFormSet = modelformset_factory(CustomerActivity, form=ActivityEntryForm, extra=0) 
    if request.method == 'POST': 
     formset = AuthorFormSet(request.POST) 

     if form.is_valid: 
      print 'form valied' 
      for form in formset: 
       print form.cleaned_data['duration'] 
      duration = request.POST.get('duration') 
      activity = request.POST.get('activity') 

      print duration 


    else: 
     formset = AuthorFormSet(queryset=qs) 

    context = { 
     'formset':formset, 
    } 
    return render(request, 'activity/activity.html', context) 

我得到一个错误：

CustomerActivityForm' object has no attribute 'duration' 

我甚至有一种形式命名CustomerActivityForm，它称为ActivityEntryForm：

class ActivityEntryForm(forms.ModelForm): 

    duration = forms.IntegerField(required=False) 

    class Meta: 
     model = CustomerActivity 
     fields = ('duration',) 

我经常表单集尝试

这是我的观点：

def display_2(request, pk=None, action='add'): 
    customer = get_customer(request) 
    entered_at, day_start, day_end = get_date_query_elements(request) 


    qs = CustomerActivity.objects.filter(customer=customer).values() 

    ArticleFormSet = formset_factory(ActivityEntryForm, extra=0) 
    if request.method == 'POST': 


     formset = ArticleFormSet(request.POST, request.FILES) 
     if formset.is_valid(): 
      for form in formset: 
       print form.duration 
      pass 
    else: 
     formset = ArticleFormSet(initial=qs) 

    context = { 
     'formset':formset, 
    } 
    return render(request, 'activity/activity.html', context) 

下面的形式：

class ActivityEntryForm(forms.Form): 
    duration = forms.IntegerField(required=False) 

在这里，我得到的错误：

ActivityEntryForm' object has no attribute 'duration' 

我如何获得持续时间值？

Answer 1

与任何形式一样，验证的数据位于form.cleaned_data，这是一本字典。

print form.cleaned_data['duration'] 

这在文档中有很详细的解释。
