Django的PasswordChangeForm AttributeError的：「PasswordChangeForm」對象有沒有屬性「cleaned_data」

Question

每當我試圖改變我的密碼作爲登錄的用戶，我收到一個AttributeError。我使用Django的內置PasswordChangeForm。誰能幫忙？

這裏是我的views.py：

from django.shortcuts import render, redirect 
from accounts.forms import (
    RegistrationForm, 
    EditProfileForm 
) 
from django.contrib.auth.models import User 
from django.contrib.auth.forms import (
    UserChangeForm, 
    PasswordChangeForm 
) 

# Create your views here. 
def home(request): 
    numbers = [1,2,3,4,5] 
    name = 'Matthew Zayas' 
    args = {'myName': name, 'numbers': numbers} 
    return render(request, 'accounts/home.html') 

def register(request): 
    if request.method == 'POST': 
     form = RegistrationForm(request.POST) 
     if form.is_valid(): 
      form.save() 
      return redirect('/account') 
    else: 
     form = RegistrationForm() 
     args = {'form': form} 
     return render(request, 'accounts/reg_form.html', args) 

def view_profile(request): 
    args = {'user': request.user} 
    return render(request, 'accounts/profile.html', args) 

def edit_profile(request): 
    if request.method == 'POST': 
     form = EditProfileForm(request.POST, instance=request.user) 

     if form.is_valid: 
      form.save() 
      return redirect('/account/profile') 
    else: 
     form = EditProfileForm(instance=request.user) 
     args = {'form': form} 
     return render(request, 'accounts/edit_profile.html', args) 

def change_password(request): 
    if request.method == 'POST': 
     form = PasswordChangeForm(data=request.POST, user=request.user) 

     if form.is_valid: 
      form.save() 
      return redirect('/account/profile') 
    else: 
     form = PasswordChangeForm(user=request.user) 
     args = {'form': form} 
     return render(request, 'accounts/change_password.html', args) 

這裏是我收到的回溯：

Exception Type: AttributeError at /account/change-password/

我不知道我做了什麼錯在這裏，因爲大部分的工作是正在被Django處理嗎？任何指針將非常感激！

找到你的問題。該表格只有當你調用is_valid()函數獲取cleaned_data屬性

你在change_password功能線不調用函數

if form.is_valid: 

變化，爲（注意括號（））

if form.is_valid(): 

這應該解決您的問題。
