django login

最近写一个django项目的时候犯懒，把admin的login form给简单的扒出来用了用，感觉还不错。

先把display_login_form给扒出来

def display_login_form(request, error_message='', extra_context=None):
    request.session.set_test_cookie()
    context = {
        'title': 'Log in',
        'app_path': request.get_full_path(),
        'error_message': error_message,
        'root_path': '',
    }
    context.update(extra_context or {})
    return render_to_response('admin/login.html', context,
        context_instance=template.RequestContext(request)
    )

然后自己再写一个login

def login(request):
    if request.POST:
        username = request.POST['username']
        password = request.POST['password']
        user = auth.authenticate(username=username, password=password)
        if user is not None and user.is_active:
            auth.login(request, user)
            return http.HttpResponseRedirect(request.get_full_path())
        else:
            return display_login_form(request,"Login error!")
    else:
        return display_login_form(request)

需要认证的地方就这样写

def login_test(request):
    if not request.user.is_authenticated():
        return login(request)
    else:
        return http.HttpResponse("Welcome %s" % request.user)

• settings.py

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

• urls.py

    (r'^login/','django.contrib.auth.views.login',{'template_name': 'admin/login.html'}),
    (r'^logout/','superman.lib.views.logout'),
