TypeError異常

Question

### views.py ###

def profile_interest_mempick(request,pk,code=None): 
"""allows user to subscribe to profile interests""" 
me = Register.objects.get(user=request.user) 
mem = Register.objects.get(pk=pk) 
if code == 's': 
    interests = mem.profile_interests.all() 
if not interests: 
    content_string = "You currently have nothuing selected" 
    return render_to_response("homepage/index.html", locals()) 
    else: 
    content_string = "To unselect an interest please uncheck it's checkbox" 
elif code == 'a': 
interests = ProfileInterest.objects.all() 
if request.method == "POST": 
form = profileInterestMemPickForm(request.POST, instance = mem) 
if form.is_valid(): 
     form.save()

    return HttpResponseRedirect('/hallo/') 
return HttpResponseRedirect('/'.format(pk)) 
else:

form.fields["profile_interest"].queryset = interests 
return HttpResponseRedirect('/profile_interest_mempick/')

類型：類型錯誤在/ profile_interest_mempick/ 異常值：profile_interest_mempick（）至少需要2個參數（1給出）

一切似乎罰款，但它不斷拋出這個異常？任何想法爲什麼？

Answer 1

檢查urls.py上的url正則表達式。

https://docs.djangoproject.com/en/dev/topics/http/urls/

模式應爲：

urlpatterns的=模式（ ''， （R '^ profile_interest_mempick /（P \ d {4}）/ $'，「news.views？。 profile_interest_mempick'），

Answer 2

回溯表明，這個問題是不是在profile_interest_mempick（）的定義，相反，問題在於使用了錯誤的參數個數調用者。
