'function' object has no attribute '_default_manager' in django 2.1

I'm trying to list the data in my table in my template, but this error appears:

  

'function' object has no attribute '_default_manager'

Model code:

class persona(models.Model):
    nombre = models.CharField(max_length=100)
    topipoid = models.CharField(max_length=50)
    identificacion = models.IntegerField()
    direccion = models.CharField(max_length=50)
    fechacreacion = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.nombre

View Code:

class personalist(ListView):
    model = persona
    template_name = "persona/persona_listar.html"

URL Code:

urlpatterns = [
  path(r'', index, name='index'),
  path(r'nuevo/', persona, name='persona'),
  path(r'listar/', personalist.as_view()),
]

Template Code:

{% extends "base/base.html" %}
{% block footer %}

<table class="table table-bordered">
    <thead>
         <tr>
        <td>#</td>
        <td>Nombre</td>
        <td>Tipo ID</td>
        <td>Direccion</td>
        <td>Fecha Creacion</td>

         </tr>
    </thead>
    <tbody>

    {% for persona in object_list %}
     <tr>
       <td>{{ persona.id }}</td>
       <td>{{ persona.Nombre }}</td>
       <td>{{ persona.topipoid }} </td>
       <td>{{ persona.Direccion }}</td>


     </tr>
    {% endfor %}


    </tbody>
