str对象没有属性'*'

Question

我想更新我的用户的密码,但我有错误

str对象没有属性'*'

if request.method == 'POST':
    form = resetPwdForm(request.POST)
    if form.is_valid():
        email = form.cleaned_data['email']
        passwordNew = form.cleaned_data['passwordNew']
        passwordConfirm = form.cleaned_data['passwordConfirm']
            #actual password is ok
        if passwordConfirm == passwordNew:
            #new password match confirm
            u = request.POST.get('username', '')
            u.set_password(passwordNew)
            u.save()

问题就在于此u.set_password(passwordNew).

Answer 1

该u不是实例User为你打算,但一个字符串值从POST表单来的模型.您需要做的是获取User实例,因为您在表单字段中获得了什么用户名

    u = User.objects.get(username=request.POST.get('username', ''))

当没有具有给定用户名的用户时,您还必须处理这种情况

    try:
        u = User.objects.get(username=request.POST.get('username', ''))
        #setting password and whatever...
    except User.DoesNotExist:
        #do something
