TypeError异常

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()
 if Register.objects.get(pk=pk) == Register.objects.get(user = request.user):
    return HttpResponseRedirect('/hallo/')
 return HttpResponseRedirect('/'.format(pk))
else:
 form = profileInterestMemPickForm(instance=me)
 form.fields["profile_interest"].queryset = interests
return HttpResponseRedirect('/profile_interest_mempick/')    
Traceback:

在/ profile_interest_mempick /上键入：TypeError    异常值：profile_interest_mempick（）至少需要2个参数（给定1个）

一切似乎都很好，但它一直在抛出这个异常？知道为什么吗？

Answer 1

检查urls.py上的url正则表达式。

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

模式应该是：

urlpatterns = patterns（''，     （r'^ profile_interest_mempick /（？P \ d {4}）/ $'，'news.views.profile_interest_mempick'），

Answer 2

回溯表明问题不在profile_interest_mempick（）的定义中。相反，问题在于其调用者使用了错误数量的参数。
