Good morning to all, the end of this message is for you can help me find the error because I do not load a template removing the 404 error:

Page not found (404)

Request URL:    http://127.0.0.1:8000/manager/panel/noticia/1/
Raised by:  manager.views.NoticiaUpdateView

No se encontró ningún noticia coincidente con la consulta

this is the admin_base template:

<li class="mm-dropdown">
                    <a href="#"><i class="menu-icon fa fa-check-square"></i><span class="mm-text">Noticias</span></a>
                    <ul>
                        <li class='{% if request.path == "/manager/panel/noticia/1/" %}active{% endif %}'>
                            <a tabindex="-1" href="{% url 'gestionar-noticia-actual' 1 %}"><span class="mm-text">Actualizar</span></a>
                        </li>

the extends:

{% extends 'admin_base.html' %}
{% block content %}
<div id="content-wrapper">
    <!-- 5. $CONTENT ===================================================================================-->
        <div class="panel">
            <div class="panel-heading">
                <span class="panel-title">GESTIONAR NOTICIA ACTUAL</span>
            </div>
            <div class="panel-body">
                <form action="" method="post" class="form-horizontal">{% csrf_token %}
                    {{ form.as_p }}
                    <input type="submit" value="Publicar" class="btn btn-success" />
                </form>
            </div>  
        </div>
</div> <!-- / #content-wrapper -->
{% endblock %}
