How to correct wrong num_times in django-taggit-templatetags?

I have the following models 

class Text(models.Model):
    text = models.CharField(max_length=10000, blank=True)
    tags = TaggableManager(blank=True)
    author = models.ForeignKey(User)
    date_created = models.DateTimeField(auto_now_add=True)
    last_modified = models.DateTimeField(auto_now=True) # changes on each edit
    public = models.BooleanField(default=1)

    def __unicode__(self):
        return self.text

class Note(models.Model):
    note = models.CharField(max_length=1000) 
    tags = TaggableManager(blank=True)
    text = models.ManyToManyField(Text)
    author = models.ForeignKey(User)
    date_created = models.DateTimeField(auto_now_add=True)
    last_modified = models.DateTimeField(auto_now=True) # changes on each edit
    public = models.BooleanField(default=1)

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

I am using django-taggit and django-taggit-templatetags. When I make a view like this:

@staff_member_required #TODO disadvantage: redirects to admin page
def labels_all(request):
    return render_to_response('labels_all.html', locals(), context_instance=RequestContext(request))

with a template like

{% extends 'base.html' %}
{% load taggit_extras %}

{% block content %}

{% get_taglist as all_labels for 'notes' %}
<div class="tag-cloud">
<ul> 
{% for label in all_labels %}
<li>  
<a href="/labels/{{ label.slug }}"> 
    <font size={{label.weight|floatformat:0}}>
    {{ label|capfirst }} ({{ label.num_times }})
    </font>
</a>
</li> 
{% endfor %}
</ul> 
</div>

Both models have a TaggableManager. I get the wrong num_times value when I make a taglist for either of the two models. The num_times I get are the number of times a specific tags occurs across the two above models (for instance, 71). I only want the number of times the tag occurs in the Note model (50).

I think the problem is in line 48 of this code: https://github.com/feuervogel/django-taggit-templatetags/blob/master/taggit_templatetags/templatetags/taggit_extras.py

It uses a call to taggit_taggeditem_items. I do not know where this comes from. In the database I have: taggit-tag (colums: id, name, slug) and taggit_taggeditem (id, tag_id, object_id, content_type_id). I do not know where it gets the _items bit, but I think it is from taggit's models.py BaseClass.

Could the problem be in the unicode method (which uses text in both models)?

In short, I want a tagcloud or taglist for a specific model. How can I use taggit and taggit-templatetags (or an alternative) to calculate tag frequencies (num_times) per model?

Thanks.

Seems the name of your app is 'notes', and Text and Note are models inside this app.

If you want only tags used in model Text, you should use:

{% get_taglist as all_labels for 'notes.Text' %}

If you want only tags used in model Note, you should use:

{% get_taglist as all_labels for 'notes.Note' %}
