Question

每当我尝试以登录用户身份更改密码时，都会收到attributeError。我正在使用Django的内置PasswordChangeForm。有人可以帮忙吗？

这是我的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)

这是我收到的追溯：

我不确定我在这里做错了什么，因为大部分工作都是由Django处理的？任何指针都会非常感激！

找到你的问题。只有在调用cleaned_data函数

时，表单才会获得is_valid()属性

您在change_password函数中的行未调用函数

if form.is_valid:

将其更改为（请注意括号（））

if form.is_valid():

这应该可以解决你的问题。

Django PasswordChangeForm AttributeError：'PasswordChangeForm'对象没有属性'cleaning_data'
