authenticate（）始终返回无

Question

• Python 3
• Django 1.5

I've successfully created a user with create_user() , and the user can log into the admin section. BUT, making code in my views.py so the user can log in anywhere else, isn't working. Here's the code I'm using, and even when the username & password are definitely correct, authenticate() still returns None .

def dologin(request):
    usrnym = request.POST['usrnym']
    psswrd = request.POST['usrpass']
    usr = authenticate(user=usrnym,password=psswrd)
    if usr is not None:
        if usr.is_active:
            login(request, usr)
            # redirect to success page
        else:
            pass
            # redirect to a 'disabled account' error message
    else:
        # return an 'invalid login' error message
        errmsg = "Invalid login. Password and username did not match."
        template = loader.get_template('fsr/loginform.html')
        context = RequestContext(request, {
            'title': "Login Page",
            'error': errmsg,
            'usr': usrnym,
            'pwd': psswrd,
            'usra': usr,
        })
        return HttpResponse(template.render(context))

Answer 1

我可能是错的，但不是吗？

usr = authenticate(username=usrnym,password=psswrd)

Answer 2

它应该是用户名而不是用户，它是一个语法错误

usr = authenticate(username = usrnym, password = psswrd)
