str对象没有属性“ *”

Question

I wanna update the password of my user but i have the error

str object has no attribute '*'

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()

The problem is on the line u.set_password(passwordNew) .

Answer 1

The u is not instance of User model as you intended but a string value coming from POST form. What you have to do is to get User instance due to what username you got in your form field

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

You also have to handle the situation when there is no such user with given username

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

Answer 2

You can get it as follow:

u = request.POST.get('username', '')
NewPassword=set_password(passwordNew)
userobj = User.objects.get(username=u)
query = User.objects.filter(username=userobj).update(password=NewPassword)
