使用表單嚮導創建不同的完成路徑 - Django

我在線學習了這個教程，但是當我嘗試有條件地在我的表單嚮導中顯示步驟時，我被卡住了。使用表單嚮導創建不同的完成路徑 - Django

views.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], 
       })

urls.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 
     })), 
.......

forms.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，我只想顯示最後一步如果用戶選擇任一「銀」選項或在步驟1中選擇的「白金」選項。現在，不管我選擇什麼，只有前兩步/表單顯示。

我認爲我的silver_ad_selected和platinum_ad_selected方法可能是問題，但我不確定。

感謝

試着改變你的urls.py：

add_forms = [AddForm1, AddForm2, AddForm3] 

urlpatterns = patterns('listings.views', 
    url(r'^addWizard/$', AddWizard.as_view(add_forms, 
     condition_dict = { 
      '2': lambda wizard: wizard.silver_ad_selected() or wizard.premium_ad_selected() 
     })),

是。問題在於我傳遞的是布爾條件而不是可調用的函數，這正是您的lambda所在。非常感謝 – AlexBrand
