表单集有效，但表单没有属性cleaned_data！ [英] formset is valid but form has no attribute cleaned_data!

问题描述

好，所以我有一个有效的表单集。但是给我一个错误，就是该表单没有属性cleaned_data。.

老实说，我完全不知道发生了什么。.

我尝试了我的代码在终端上，它返回了一个空字典。.没有错误。。

表格：

  class Clinical（forms.Form）：
 _names = list（ClinicalForm.objects.values_list（'form_id'，'form_name'））
 _names.append（（ New，u 'Nova entrada'））
 
 cliform_name = form.ChoiceField（widget = RadioSelect（），choices__names，标签
 =，required = True）
  

视图：

  ClinicalSet = formset_factory（Clinical，extra = 2）
 
 formset2 = ClinicalSet（request.POST）
 if formset2.is_valid（）：
 choice1 = formset2.cleaned_data 
返回render_to_response （'valid_test.html'，
 {
'formset2'：formset2，
 'wrongs1'：errorss1，
'choice1'：choice1 
}）
 else：
 formset2 = ClinicalSet（）
 return render_to_response（'valid_test.html'，
 {
'formset2'：formset2，
'wrongs1'：errorss1，
}）
  

模板：

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

的cleaned_data称为（choice1），我没有收到任何错误，我可以看到表格。.

如果我选择了一些选项并取消了对此行的注释，则可以正常工作。 >

我有一个相似的表单集：都需要选择表单集中的两个表单，这个表单才能起作用。

起作用的表单是第一个表单集（上面链接）。 post参数：

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

用户在每种表单中选择一个选项，然后重定向

任何帮助都非常受欢迎。

解决方案

formset_factory 返回一个表单迭代器，即本质上是一个表单列表，它不是表单本身。 cleaned_data 仅在表单上可用，因此您必须遍历 formset2 ：

  for formset2中的表单：
 form.cleaned_data＃我在这里！ 
  

Ok, so I have a formset that is valid. But gives me a error that that form has no attribute cleaned_data..

Honestly I have absolutely no clue what's happening..
I tried my code on terminal and it returned a empty dictionary.. without errors..

forms:

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)

views:

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,
                                })    

template:

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

If I comment the line where the cleaned_data is called (choice1), I don't receive any error and I'm able to see the forms..
If I select some options and uncomment this line, it works..

I have a similar formset : both forms in formset need to be selected and this one works..

the form that works is the first formset (linked above). The post parameters:

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

the user select one option in each form and he's redirect to another view (this one - formset2).

Any help is more than welcome..

解决方案

formset_factory returns a form iterator, i.e. essentially a list of forms, it is not a form itself. cleaned_data is only available on the form, so you have to iterate over formset2:

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