Question

当我在detail.html中输入注销按钮时出现错误，找不到页面（404）。我在header.html中写道

<header class="clearfix">
      <h1 class="title">WEB SITE</h1>

      <div class="collapse navbar-collapse head_content" id="navbarNavDropdown">
        <ul class="navbar-nav top-menu">
          <li class="nav-item top-menu-item"><i class="fa fa-plus" aria-hidden="true">
            <a class="nav-link icon_head" href="/accounts/see">SEE</a></i>
          </li>
          <li class="nav-item dropdown top-menu-item"><i class="fa fa-eye" aria-hidden="true">
            <a class="nav-link dropdown-toggle icon_head" href="" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
              KNOW
            </a>
            <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
              <div class="dropdown-content">
              <a class="dropdown-item" href="/accounts/nowknow">KNOW1</a>
              </div>
              <div class="dropdown-content">
              <a class="dropdown-item" href="/accounts/pastknow">KNOW2</a>
              </div>
            </div>
            </i>
          </li>  
        </ul>
      </div>
      <a class="logout_button" href="/accounts/logout_view">LOGOUT</a>
</header>

我在views.py中写道

    @login_required
    def logout_view(request):
        logout(request)
        return redirect('regist')

    @login_required
    def regist(request):
        return render(request, 'registration/regist.html')

    @login_required
    def see(request):
        return render(request, 'registration/see.html')

    @login_required
    def nowknow(request):
        return render(request, 'registration/nowknow.html')

    @login_required
    def pastknow(request):
        return render(request, 'registration/pastknow.html')

   @login_required
    def detail(request):
        return render(request, 'registration/detail.html')

在urls.py中

urlpatterns = [
    url(r'^product$', views.logout_view,name='logout_view'),
    url(r'^past_result$', views.see,name='see'),
    url(r'^privacy_policy$', views.nowknow,name='nowknow'),
    url(r'^privacy_policy$', views.pastknow,name='pastknow'),
    url(r'^detail$', views.detail,name='detail'),
]

我在index.html中写道

<html lang="ja">

<head>
    <meta charset="UTF-8">
    <script src="https://code.jquery.com/jquery-1.11.0.min.js"></script>

    <title>WEB SITE</title>
</head>

<body class="relative">
{% include '../header.html' %}

    <main>
    <p>HELLO WORLD</p>
    </main>
</body>
</html>

当我执行index.html并放置LOGOUT链接时，注销就完成了。但我在detail.html中写道

<html lang="ja">

<head>
    <meta charset="UTF-8">
    <script src="https://code.jquery.com/jquery-1.11.0.min.js"></script>

    <title>DETAIL</title>
</head>

<body class="relative">
{% include '../header.html' %}

    <main>
    <p>HOGE</p>
    </main>
</body>
</html>

并把LOGOUT链接，错误发生。在这个时候，请求URL是http://localhost:8000/accounts/detail/logout_view.I真的无法理解为什么会发生这个错误。我写了2个HTML同样的方式，所以我不知道为什么一个HTML是好的但是另一个导致错误。我该如何解决这个问题？

Answer 1

出于某种原因，您已将logout_view视图的URL定义为“product”，因此这是您需要使用的URL。

要避免此类问题，您应始终使用{% url %}标记生成网址，而不是在模板中对其进行硬编码：

<a class="logout_button" href="{% url 'logout_view' %}">LOGOUT</a>

页面未找到（404）错误发生
