I'm trying to make an encrypted field. I'm using some of the code from the

Also, convention seems to be to spell out the field names. Because of
a different namespaces, you shouldn't have to worry about too much
name clashing. And if you don't provide an ID for your model, one is
automatically created for you. For example:
class Category(models.Model):
name =
Your problem is here:
def category_entry(request, category):
entries_in_cat = Entry.objects.filter(entry_cat=category)
return render_to_response('blog/index.html', locals())
Remember, the value of "category" is a string. One way or another you
need adjust the filter. Something

One more note. You wouldn't NEED to explicitly grab all those vars,
as you can get them in a template too. I just wanted to show you the

If you sent the track to the template, you can get the artist by
using:
{{ track.album.artist }}

The only part you have that is redundant is the "artist" in your

to an album, which in turn, is related to an artist.
