我一直在在线学习教程，但是在尝试有条件地在表单向导中显示步骤时遇到了困难。
视图.py
def silver_ad_selected(wizard):
cleaned_data = wizard.get_cleaned_data_for_step('0') or {}
return cleaned_data.get('ad_type') == '2'
def platinum_ad_selected(wizard):
cleaned_data = wizard.get_cleaned_data_for_step('0') or {}
return cleaned_data.get('ad_type') == '3'
class AddWizard(SessionWizardView):
def done(self, form_list, **kwargs):
return render_to_response('business/done.html', {
'form_data': [form.cleaned_data for form in form_list],
})
网址.py：
add_forms = [AddForm1, AddForm2, AddForm3]
urlpatterns = patterns('listings.views',
url(r'^addWizard/$', AddWizard.as_view(add_forms,
condition_dict = {
'2': silver_ad_selected or premium_ad_selected
})),
.......
表格.py
class AddForm1(forms.Form):
TYPE_CHOICES = (
('1','Basic'),
('2','Silver'),
('3','Platinum')
)
ad_type = forms.ChoiceField(choices=TYPE_CHOICES, widget=forms.RadioSelect)
class AddForm2(forms.Form):
category = forms.ModelChoiceField(queryset = Category.objects.all())
city = forms.ModelChoiceField(queryset = City.objects.all())
name = forms.CharField(max_length = 200)
address = forms.CharField(max_length = 200)
slogan = forms.CharField(max_length=140)
phone = forms.CharField(max_length=10)
website = forms.URLField()
email = forms.EmailField()
class AddForm3(AddForm2):
twitter = forms.CharField(max_length=100)
facebook = forms.URLField()
description = forms.CharField(widget=forms.Textarea)
基本上，如果用户选择在步骤 1 中选择的“银”选项或“白金”选项，我只想显示最后一步。现在，无论我选择什么，只有前两个步骤/表格显示。
我认为我的silver_ad_selected和platinum_ad_selected方法可能是问题所在，但我不确定。
谢谢
