Django cleaning_data KeyError

Question

在我的Django应用程序中，我有三种形式：

class RoomsForm(forms.Form):
        rooms = forms.IntegerField(min_value=1)

class TouristsForm(forms.Form):
        adult = forms.IntegerField(label=(u'Adults'), min_value=1, initial=1, widget = forms.HiddenInput)
        children = forms.IntegerField(label=(u'Children'), min_value=1, required=False, widget = forms.HiddenInput)

class ChildrenAgeForm(forms.Form):
        children_age = forms.IntegerField(min_value=2, max_value=10, required=False, widget = forms.HiddenInput)

在view.py中我尝试清理数据：

def RoomsForm(request):
        TouristsFormSet = formset_factory(TouristsForm)
        ChildrenAgeFormSet = formset_factory(ChildrenAgeForm)
        if request.method == 'POST':
                rooms_form = RoomsForm(request.POST, prefix='rooms_form')
                tourists_formset = TouristsFormSet(request.POST, prefix='tourists')
                childrenage_formset = ChildrenAgeFormSet(request.POST, prefix='childrenage')
                if rooms_form.is_valid() and tourists_formset.is_valid() or childrenage_formset.is_valid():
                        rooms = rooms_form.cleaned_data['rooms']

                        for i in range(0, tourists_formset.total_form_count()):
                                tourists_form = tourists_formset.forms[i]
                                print tourists_form.cleaned_data

但它总是在/ rooms /＆＃39; rooms＆＃39;上升错误KeyError。 有人可以帮我吗？

在这一行中，您使用的是or而不是and，因此无法保证rooms_form无效。

if rooms_form.is_valid() and tourists_formset.is_valid() or childrenage_formset.is_valid():

当rooms_form无效时，room不在rooms_form.cleaned_data，因此您获得了KeyError。
