Django：登录用户并在同一页面刷新而不定义模板？ [英] Django: login user and refresh on same page without defining a template?

问题描述

我正在尝试使用自举下拉式登录表单让用户登录。我可以硬编码我的用户名和密码，并验证正常，但我试图有一个用户登录，而不去登录屏幕。这是我的代码：

模板：
我使用动作调用logUserIn url，以便表单可以发布到该视图。

 < ul class =nav pull-right> 
 {％if user.is_authenticated％} 
< li>< a>欢迎{{user.first_name}}< / a>< / li> 
< li class =divider-vertical>< / li> 
< li>< a href ={％url'caesarWorkflowApp.views.logUserOut'％}>注销< / a>< / li> 
< li class =divider-vertical>< / li> 
 {％else％} 
< li class =dropdown> 
< a class =dropdown-togglehref =＃data-toggle =dropdown>登录< strong class =caret>< / strong>< / a> 
< div class =dropdown-menustyle =padding：15px; padding-bottom：0px;> 
< form action ={％url'caesarWorkflowApp.views.logUserIn'％}method =postaccept-charset =UTF-8> 
 {％csrf_token％} 
< input id =user_usernamestyle =margin-bottom：15px; type =textname =usernameplaceholder =Usernamesize =30/> 
< input id =user_passwordstyle =margin-bottom：15px; type =passwordname =passwordplaceholder =Passwordsize =30/> 
< input id =user_remember_mestyle =float：left; margin-right：10px; type =checkboxname =user [remember_me]value =1/> 
< label class =string optionalfor =user_remember_me>记住我< / label> 
< input class =btn btn-primarystyle =clear：left; width：100％; height：32px; font-size：13px; type =submitname =commitvalue =登录/> 
< / form> 
< / div> 
< / li> 
 {％endif％} 
< li class =divider-vertical>< / li> 
< / ul> 
  

URLS：

  urlpatterns = patterns（''，
 url（r'^ $'，'caesarWorkflowApp.views.home'，name ='default'），
 url（r'^ $'，'caesarWorkflowApp.views .logUserIn'），
 url（r'^ $'，'caesarWorkflowApp.views.logUserOut'），
）
  

VIEWS：
然后我有这个登录视图不起作用，因为即使表单成功发布，控制台甚至不打印输入。我发错了吗称错误行为？ 有没有人知道如何创建登录/注销视图，而不创建一个模板，以便它只是刷新/重定向到主页？

  def logUserIn（request）：
 if request.method =='POST'：
 print'enter'
 username = request.POST ['username '] 
 password = request.POST ['password'] 
 user = authenticate（username = username，password = password）
如果用户不是没有：
＃验证密码对于用户
如果user.is_active：
登录（请求，用户）
打印（用户有效，活动和验证）
 
 else：
 print（密码有效，但帐户已被禁用！）
其他：
＃验证系统无法验证用户名和密码
 print（用户名密码不正确。）
 
 response = render_to_response（'home.html'，{}，context_instance = RequestContext（request））
返回响应
  

我也希望页面不要问我是否要重新加载，因为它的帖子形式，我相信这是解决方案，以防任何人对此感兴趣：停止要刷新刷新表单数据的浏览器？

谢谢！

解决方案

我无法让AJAX工作，所以我想出了这个解决方案： p>

TEMPLATE：

 < ul class =nav pull-right > 
 {％if user.is_authenticated％} 
< li>< a>欢迎，{{user.first_name}}< / a>< / li> 
< li class =divider-vertical>< / li> 
< li>< a href =/ logout />注销< / a>< / li> 
< li class =divider-vertical>< / li> 
 {％else％} 
< li class =dropdown> 
< a class =dropdown-togglehref =＃data-toggle =dropdown>登录< strong class =caret>< / strong>< / a> 
< div class =dropdown-menustyle =padding：15px; padding-bottom：0px;> 
< form id =form-loginaction =/method =postaccept-charset =UTF-8> 
 {％csrf_token％} 
< input id =user_usernamestyle =margin-bottom：15px; type =textname =usernameplaceholder =Usernamesize =30/> 
< input id =user_passwordstyle =margin-bottom：15px; type =passwordname =passwordplaceholder =Passwordsize =30/> 
< input id =user_remember_mestyle =float：left; margin-right：10px; type =checkboxname =user [remember_me]value =1/> 
< label class =string optionalfor =user_remember_me>记住我< / label> 
< input class =btn btn-primarystyle =clear：left; width：100％; height：32px; font-size：13px; type =submitname =commitvalue =登录/> 
< / form> 
< / div> 
< / li> 
< li class =divider-vertical>< / li> 
 {％endif％} 
< / ul> 
  

URLS：

 code> urlpatterns = patterns（''，
 url（r'^ $'，'caesarWorkflowApp.views.home'，name ='default'），
 url（r'^ login / $'，'caesarWorkflowApp.views.logUserIn'），
 url（r'^ logout / $'，'caesarWorkflowApp.views.logUserOut'），
）
  

查看：

  def logUserIn（request） ：
 print'enter'
 username = request.POST ['username'] 
 password = request.POST ['password'] 
 user = authenticate（username = username，password = password）
如果用户不是没有：
＃验证用户的密码
如果user.is_active：
登录（请求，用户）
 print（用户有效，有效和认证）
 
其他：
打印（密码有效，但帐户已被禁用！）
其他：
 ＃认证系统是无法验证用户名和密码
 print（用户名和密码不正确）
 
 response = render_to_response（'home.html'，{}，context_instance = RequestContext（request） ）
 return response 
 
 def logUserOut（request）：
 logout（request）
 return HttpResponseRedirect（'/'）
  

完美工作，真好看！ =）

I'm trying to use a bootstrap drop-down sign in form to have users login. I'm able to hard code my username and password and authenticate just fine but I'm trying to have a user login without going to a login screen. Here is my code:

Template: I use action to call the logUserIn url so that the form can post to that view.

<ul class="nav pull-right">
          {% if user.is_authenticated %}
          <li><a> Welcome {{ user.first_name }} </a></li>
          <li class="divider-vertical"></li>
          <li><a href="{% url 'caesarWorkflowApp.views.logUserOut' %}">Log Out</a></li>
          <li class="divider-vertical"></li>
          {% else %}
          <li class="dropdown">
            <a class="dropdown-toggle" href="#" data-toggle="dropdown">Sign In <strong class="caret"></strong></a>
            <div class="dropdown-menu" style="padding: 15px; padding-bottom: 0px;">
              <form action="{% url 'caesarWorkflowApp.views.logUserIn' %}" method="post" accept-charset="UTF-8">
                {% csrf_token %}
                <input id="user_username" style="margin-bottom: 15px;" type="text" name="username" placeholder="Username" size="30" />
                <input id="user_password" style="margin-bottom: 15px;" type="password" name="password" placeholder="Password" size="30" />
                <input id="user_remember_me" style="float: left; margin-right: 10px;" type="checkbox" name="user[remember_me]" value="1" />
                <label class="string optional" for="user_remember_me"> Remember me</label>
                <input class="btn btn-primary" style="clear: left; width: 100%; height: 32px; font-size: 13px;" type="submit" name="commit" value="Sign In" />
              </form>
            </div>
          </li>
            {% endif %}
          <li class="divider-vertical"></li>
        </ul>

URLS:

urlpatterns = patterns('',
    url(r'^$', 'caesarWorkflowApp.views.home', name='default'),
    url(r'^$', 'caesarWorkflowApp.views.logUserIn'),
    url(r'^$', 'caesarWorkflowApp.views.logUserOut'),
)

VIEWS: Then I have this view for login which doesn't work because console never even print 'enter' even though the form is posting successfully. Am I posting wrong? Calling the wrong action? Does anyone know how to create a login/logout view without creating a template for it so that it just refreshes/redirects to the home page?

def logUserIn(request):
    if request.method == 'POST':
        print 'enter'
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(username=username, password=password)
        if user is not None:
            # the password verified for the user
            if user.is_active:
                login(request, user)
                print("User is valid, active and authenticated")

            else:
                print("The password is valid, but the account has been disabled!")
        else:
            # the authentication system was unable to verify the username and password
            print("The username and password were incorrect.")

    response = render_to_response('home.html', {}, context_instance=RequestContext(request))
    return response

I also want the page to not ask me if I want to reload since the it's post form and I believe this is the solution in case anyone is interested in that: Stop browsers asking to resend form data on refresh?

Thank you!

解决方案

I couldn't get AJAX working so I just came up with this solution:

TEMPLATE:

<ul class="nav pull-right">
          {% if user.is_authenticated %}
          <li><a> Welcome, {{ user.first_name }} </a></li>
          <li class="divider-vertical"></li>
          <li><a href="/logout/">Log Out</a></li>
          <li class="divider-vertical"></li>
          {% else %}
          <li class="dropdown">
            <a class="dropdown-toggle" href="#" data-toggle="dropdown">Sign In <strong class="caret"></strong></a>
            <div class="dropdown-menu" style="padding: 15px; padding-bottom: 0px;">
              <form id="form-login" action="/" method="post" accept-charset="UTF-8">
                {% csrf_token %}
                <input id="user_username" style="margin-bottom: 15px;" type="text" name="username" placeholder="Username" size="30" />
                <input id="user_password" style="margin-bottom: 15px;" type="password" name="password" placeholder="Password" size="30" />
                <input id="user_remember_me" style="float: left; margin-right: 10px;" type="checkbox" name="user[remember_me]" value="1" />
                <label class="string optional" for="user_remember_me"> Remember me</label>
                <input class="btn btn-primary" style="clear: left; width: 100%; height: 32px; font-size: 13px;" type="submit" name="commit" value="Sign In" />
              </form>
            </div>
          </li>
          <li class="divider-vertical"></li>
          {% endif %}
        </ul>

URLS:

urlpatterns = patterns('',
    url(r'^$', 'caesarWorkflowApp.views.home', name='default'),
    url(r'^login/$', 'caesarWorkflowApp.views.logUserIn'),
    url(r'^logout/$', 'caesarWorkflowApp.views.logUserOut'),
)

VIEWS:

def logUserIn(request):
    print 'enter'
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(username=username, password=password)
    if user is not None:
        # the password verified for the user
        if user.is_active:
            login(request, user)
            print("User is valid, active and authenticated")

        else:
            print("The password is valid, but the account has been disabled!")
    else:
        # the authentication system was unable to verify the username and password
        print("The username and password were incorrect.")

    response = render_to_response('home.html', {}, context_instance=RequestContext(request))
    return response

def logUserOut(request):
    logout(request)
    return HttpResponseRedirect('/')

Works perfectly and really nice looking! =)
