[Tutor] A Django Beginner View Question

[Alasdair Macmillan]

Hi

I am building my first Django site which has a lot of effectively 'static' pages where I just want to make the meta data and text editable.

The model is

models.py

class About(models.Model):
    page_title = models.CharField(max_length=900, help_text='Text at top of browser window')
    meta_keywords = models.CharField(max_length=900, help_text='Keywords (for SEO)')
    meta_description = models.CharField(max_length=160, help_text='Description (for SEO)')
    logo_header = models.CharField(max_length=900, help_text='H1 Header (for SEO)')
    header = models.CharField(max_length=60)
    body = models.TextField()
    last_updated = models.DateTimeField(default=datetime.datetime.now, primary_key=True)
    
    class Meta:
        get_latest_by = "last_updated"
        verbose_name_plural = "About Page"
#        managed = False
    
def __unicode__(self):
    return self.title


I'm trying to understand how to either write a model that only allows a single entry or write a view that will take either a single entry or the most recent entry.

views.py

def about(request):
	return render_to_response('about.html',
								{ 'About' : About.objects.latest() })
urls.py

    (r'^about/$', 'harkproject.cms.views.about'),

Much appreciated
