Django cleaned_data KeyError

In my Django app i have three forms:

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)

in view.py i try to clean data:

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

but it always rise the error KeyError at /rooms/ 'rooms'. Can somebody help me with it?

In this line, you are using or instead of and, so you are not guaranteed that rooms_form is valid.

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

When rooms_form is invalid, room is not in rooms_form.cleaned_data, so you get the KeyError.
