[Fixed]-Django request.user.is_superuser doesn't work

You want this Generic view:

class IniciView(ListView):
    template_name = 'principal/inici.html'
    model = Zona

are the context processors in settings?

This is more redeable:

{% if user.is_authenticated %}
    <ul>                    
      <li class="nivell1">
        <a href="/accounts/logout/?next=/">Logout</a> 
      </li>               
      <li class="nivell1">
        <a class="nivell1" herf="#"> Configuració </a>          
      </li>

    {% if user.is_superuser %}                      
      <li class="nivell1">
        <a href="zona/crear/">Crear zona</a>
      </li>   
    {% endif %}             
</ul>  
{% else %}  
    ...
{% endif %}

I’ve changed {% if request.user.is_superuser %} to {% if user.is_superuser %}
