How to avoid this combobox?

Question

I created a model playlist form and elements like this:

class playlistmodel(models.Model):
    user = models.ForeignKey(User)
    title = models.CharField(max_length=200)
    def __unicode__(self):
            return self.title

class itemsmodel(models.Model):
    playlist = models.ForeignKey(playlistmodel)
    item = models.TextField()

    def __unicode(self):
            return self.item
class playlistform(ModelForm):
    class Meta:
            model = playlistmodel

class itemsform(ModelForm):
    class Meta:
            model = itemsmodel

My playlist view:

def playlistview(request):
    if request.method == 'POST':
            form = playlistform(request.POST)
            if form.is_valid():
                    data = form.save(commit=False)
                    data.user = request.user
                    a = data.save()
                    return render_to_response('playlist.html', {'data': a})
    else:
            form = playlistform()
            playlistmodel.user.id = request.user.id
            return render_to_response('playlist.html', {'form': form}, context_instance=RequestContext(request))

I also installed the login script. If you need to create a playlist, you need to log in, and the problem is that when I try to create a playlist after logging in, it displays all the users in the drop-down list with a list to select which user and enter the title of the playlist, What if I want to do to remove this useless dropdown. It also shows for the page element, for example, the selection of a playlist in the drop-down list and input of elements.

Thank.
