Django - 使用通用登录视图无法正常工作

编辑：当我输入正确的用户名和密码时，视图现在会登录，但是当我输入错误的用户名和密码时，不会返回任何错误 . 我正在使用Django提供的通用登录视图 . 这是我的login.html模板：

<body>
    <h1>User Login</h1>

    {% if form.has_errors %}
        <p>Your username and password did not match. 
        Please try again.</p>
    {% else %}
        <form method="post" action=" . ">{% csrf_token %}
            <p><label for="id_username">Username:</label>
            {{ form.username }}</p>

            <p><label for="id_password">Password:</label>
            {{ form.password }}</p>

            <input type="hidden" name="next" value="/" />
            <input type="submit" value="login" />
        </form>
    {% endif %}
</body>

现在，我正在阅读“Pact Publishing . 使用Django学习网站开发”一书中的教程 . 视图永远不会返回

form.has_errors

即使我故意提交错误的用户名和密码 . 点击提交后，它一直让我回到同一页面 . 另外，根据我读过的HTML书，它说表单中的'action'属性是服务器上将检索信息的页面的URL . 这就是为什么它不起作用？因为我的

action=" . "

？

编辑：视图是通用登录视图：

@sensitive_post_parameters()
@csrf_protect
@never_cache
def login(request, template_name='registration/login.html',
          redirect_field_name=REDIRECT_FIELD_NAME,
          authentication_form=AuthenticationForm,
          current_app=None, extra_context=None):
    """
    Displays the login form and handles the login action.
    """
    redirect_to = request.REQUEST.get(redirect_field_name, '')
    if request.method == "POST":
        form = authentication_form(data=request.POST)
        if form.is_valid():

            # Ensure the user-originating redirection url is safe.
            if not is_safe_url(url=redirect_to, host=request.get_host()):
                redirect_to = resolve_url(settings.LOGIN_REDIRECT_URL)

            # Okay, security check complete. Log the user in.
            auth_login(request, form.get_user())

            if request.session.test_cookie_worked():
                request.session.delete_test_cookie()

            return HttpResponseRedirect(redirect_to)
    else:
        form = authentication_form(request)

    request.session.set_test_cookie()

    current_site = get_current_site(request)

    context = {
        'form': form,
        redirect_field_name: redirect_to,
        'site': current_site,
        'site_name': current_site.name,
    }
    if extra_context is not None:
       context.update(extra_context)
    return TemplateResponse(request, template_name, context,
                            current_app=current_app)

而我的urls.py就是

url(r'^$', main_page),
url(r'^user/(\w+)/$', user_page), 
url(r'^login/$', login),
python django login django-generic-views

    试试这个 .

    Login.Html

    <form action ="." method = POST>
        {% csrf_token %}    
        {{ form.as_p }}

        <input type = "submit" value = "login" class="btn">

    </form>

    urls.py

    from django.contrib.auth.views import login, logout
from django.conf.urls import *

urlpatterns = patterns('',
    url(r'login/',login,kwargs = {'template_name' : 'templates/auth/login.html'},
    url(r'logout', logout,kwargs = {'template_name' : 'templates/auth/logout.html'}),
)

    settings.py

    LOGIN_REDIRECT_URL  = '/dashboard'
LOGIN_URL           = '/login/'
