Question

Django告诉我,我的原木认为是一只HttpResponse物体返回的:

The view accounts.views.login didn t return an HttpResponse object.

然而,使用<代码>render_to_response()的Im,在不做出答复的情况下,这种观点根本无法解决。该法典:

def login(request):
    if request.method ==  POST :
        form = LoginForm(request.POST)
        if form.is_valid():
            username = request.POST[ username ]
            password = request.POST[ password ]
            user = authenticate(username=username, password=password)
            if user is not None:
                if user.is_active:
                    auth_login(request, user)
                    render_to_response( list.html )
                else:
                    error = "It seems your account has been disabled."
                    render_to_response( list.html , { error : error})
            else:
                error = "Bad login information. Give it another go."
                render_to_response( list.html , { error : error})
        else:
            error = "Bad login information. Give it another go."
            render_to_response( list.html , { error : error})
    else:
        error = "Whoa, something weird happened. You sure you re using the form on our site?"
        render_to_response( list.html , { error : error})

我确信,这部法典可以提高效率(无助),但这应当行之有效?

Answer 1

You are missing the return

return render_to_response( list.html , { error : error})

Answer 2

您需要将答复内容从中转至答复。我建议你改进一些法典:

def login(request):
    if request.method ==  POST :
        form = LoginForm(request.POST)
        if form.is_valid():
            username = request.POST[ username ]
            password = request.POST[ password ]
            user = authenticate(username=username, password=password)
            if user is not None:
                if user.is_active:
                    auth_login(request, user)
                    return render_to_response( list.html )
                else:
                    error = "It seems your account has been disabled."
            else:
                error = "Bad login information. Give it another go."
        else:
            error = "Bad login information. Give it another go."
    else:
        error = "Whoa, something weird happened. You sure you re using the form on our site?"
    return render_to_response( list.html , { error : error})
