en la carpeta templates tengo un archivo base.html y el error que tengo es que no aparece nada en:
"{% url searchresults %}"
"{% url mainpage %}"
base.html
Código HTML:
{% load static %}
{% get_static_prefix as STATIC_URL %}
<!DOCTYPE HTML>
<html>
<head>
<title>Mi blog | {% block title %}Un título genérico{% endblock %}</title>
<link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}style.css">
</head>
<body>
<form action="{% url searchresults %}" method="GET">
<p>{{ searchform.query.errors }}</p>
<label>Buscar: {{ searchform.query }}<input type="submit" value="Buscar"></label>
</form>
<header>
<h1><a href="{% url mainpage %}">Mi blog</a></h1>
</header>
{% block content %}Un contenido genérico{% endblock %}
</body>
</html> y el siguiente error entre en post.html ya que no me da el resultado y cuando borro estos 4 problemas se ve la pagina
"{% url postdetails post.machine_name %}"
"{% url postdetails post.machine_name %}#commentaries"
post.html
