Question

好的，所以我有一个有效的formset。但是给我一个错误，那个表单没有属性cleaning_data ..

老实说，我完全不知道发生了什么事我在终端上尝试了我的代码并返回了一个空字典..没有错误..

形式：

class Clinical(forms.Form):
    _names = list(ClinicalForm.objects.values_list('form_id', 'form_name'))
    _names.append(("New", u'Nova entrada'))

    cliform_name = forms.ChoiceField(widget=RadioSelect(), choices=_names, label
         ="", required=True)

的观点：

ClinicalSet = formset_factory(Clinical, extra=2)

formset2 = ClinicalSet(request.POST)
if formset2.is_valid():
    choice1 = formset2.cleaned_data
    return render_to_response('valid_test.html', 
                                {
                                    'formset2': formset2,
                                    'wrongs1': wrongs1,
                                    'choice1': choice1 
                                    })
else:
    formset2 = ClinicalSet()
return render_to_response('valid_test.html', 
                            {
                                'formset2': formset2,
                                'wrongs1': wrongs1,
                                })

模板：

<form method="post" action="">
<div>
{{ formset2.management_form }}
    {% for form in formset2.forms %}
        {{ form }}
    {% endfor %} 
    <input type="submit" value="save" />
</div>

如果我评论调用cleaning_data的行（choice1），我没有收到任何错误，我可以看到表格..
如果我选择一些选项并取消注释这一行，它就可以工作..

我有一个类似的形式集：both forms in formset need to be selected，这个有效..

有效的表单是第一个formset（上面链接）。帖子参数：

form-0-pres_name    1
form-1-pres_name    2
form-INITIAL_FORMS  0
form-TOTAL_FORMS    2

用户在每个表单中选择一个选项，然后重定向到另一个视图（这个 - formset2）。

任何帮助都非常受欢迎..

Answer 1

formset_factory返回一个表单迭代器，即基本上是一个表单列表，它本身不是表单。 cleaned_data仅适用于表单，因此您必须遍历formset2：

for form in formset2:
    form.cleaned_data # Here I am!

Answer 2

如果有人需要，以下是我在视图中所做的修改：

 ClinicalSet = formset_factory(Clinical, extra=tamanh)

 #size of this list will determine number of forms
 wrongs = iter(wrong)
 formset = ClinicalSet(request.POST)
 dic = {}
 if formset.is_valid():
     if len(request.POST.keys()) == 0:
         return render_to_response('valid.html',  
                                        {
                                            'formset': formset,
                                            'wrongs': wrongs })
     else:
         #+ 2 because of TOTAL_FORMS and MAX_NUM_FORMS
         if len(request.POST.keys()) != len(wrongs) + 2:
             msg = "You have to select something in all forms!!"
             return render_to_response('valid.html', 
                                            {
                                                'formset': formset,
                                                'wrongs': wrongs,
                                                'msg': msg })
         else:
             for n in range(tamanh):
                 #result post into a dictionary, since cleaned_data doesn't work
                 dic[wrongs.next()] = request.POST['form-' + str(n) + '-cliform_name']
                 return HttpResponseRedirect(reverse('valid2', args=[word]))
    else:
        formset = ClinicalSet()
    return render_to_response('valid.html', 
                                {
                                    'formset': formset,
                                    'wrongs': wrongs,
                                    'msg': msg
                                    })

formset有效但表单没有属性cleaning_data！
