views.py

def profile(request,nav="profile",template="profile.html",context = {},extra_context = None): 
    if request.POST: 
     if 'profileFormSubmit' in request.POST: 
      pform = UserProfileForm(request.POST,instance = request.user) 
      if pform.is_valid(): 
       try: 
        user = pform.save() 
        return redirect(profile,nav="profile") 
        except RuntimeError as e: 
        return HttpResponse(e)

誤差

The User could not be changed because the data didn't validate.

線

user = super(UserProfileForm,self).save(*args,**kw)

疑問

形式沒有得到驗證，因爲我是在我的元級的UserProfileForm，這是不應該出現的使用「用戶名」。

接受你的答案這樣的問題將無法保持開放。 – jdi

在清潔之前，您正在調用保存在窗體上。你要保存兩次。一旦在表單保存的開始。最後一次。

pform.is_valid（）返回一個布爾值，你永遠不會檢查。

我已經改變了一點，但還是我得到的錯誤UserProfileForm可是沒有一個cleaned_data屬性 – Abhimanyu

cleaned_data不會存在，直到您驗證表單後。您必須檢查is_valid，或者直接調用clean方法。基本上你沒有先清理掉保存方法。 – jdi

我已經單獨清洗所有的領域，如clean_first_name ...等。，但我仍然得到相同的錯誤 – Abhimanyu
