Question

我正在尝试使用此处的表单设置登录 -

点击登录后，我得到以下追溯 -

Traceback:

Exception Type: TemplateDoesNotExist at /login/
Exception Value: /

这是我的观点 -

def LoginRequest(request):
    if request.user.is_authenticated():
        return HttpResponseRedirect(request.META.get('HTTP_REFERER', '/'))
    if request.method == 'POST':
        form = LoginForm(request.POST)
        if form.is_valid():
            email = form.cleaned_data['email']
            password = form.cleaned_data['password']
            user = authenticate(email=email, password=password)
            if user is not None:
                login(request, user)
                return HttpResponseRedirect(request.META.get('HTTP_REFERER', '/'))
            else:
                return render_to_response('/', {'form': form}, context_instance=RequestContext(request))
        else:
            return render_to_response('/', {'form': form}, context_instance=RequestContext(request))
    else:
        form = LoginForm()
        return render_to_response('/', {'form': form}, context_instance=RequestContext(request))

我只能对模板进行成像，因为它不是模板。我正在尝试做的是让我的视图登录，然后返回我的根网址。

Answer 1

您需要在template_name中传递render_to_response。您没有这样做，而是传递url。

render_to_response的基本签名：

render_to_response(template_name[, context][, context_instance][, content_type][, status][, dirs][, using])

这将使用给定的template字典呈现给定的context并返回带有该呈现文本的HttpResponse对象。

所以下面的陈述不应该是：

return render_to_response('/', {'form': form}, context_instance=RequestContext(request))

但是类似于：

return render_to_response('template_name_of_index_page', {'form': form}, context_instance=RequestContext(request))

我不得不恢复以下视图 -

def LoginRequest(request):
    active = "index"
    message = ""
    if request.user.is_authenticated():
        return HttpResponseRedirect(request.META.get('HTTP_REFERER', '/'))
    else:
        if request.method == "POST":
            form = LoginForm(request.POST)
            if form.is_valid():
                username = form.cleaned_data['email']
                password = form.cleaned_data['password']
                user = authenticate(username=username,password=password)
                if user is not None and user.is_active:
                    login(request,user)
                    return HttpResponseRedirect('/dashboard')
                else:
                    message = "user and/or password incorrect"


    ctx = {'active':active, 'form': form}
    return render_to_response('index.html',ctx,context_instance=RequestContext(request))

现在没有问题。
