    text = models.TextField()
    header_image = models.FileField(upload_to='blog/%Y/%m/%d', null=True, blank=True)
    post_color = models.CharField(max_length=20, null=True)
    tags = models.CharField(max_length=80, blank=True)
    published = models.BooleanField(default=True)

    def __unicode__(self):
        return u'%s' % self.title

    def get_absolute_url(self):
        return reverse('blog.views.post', args=[self.slug])

views.py

from django.shortcuts import render, get_object_or_404
from blog.models import Post

def about(request):
        # get the blog posts …
