How do I link the User model with a Taxonomy model? - django

Question

How do I link the User model with a Taxonomy model. How do add terms for a specific user and how can I retrieve them?
I'm quite new to Django so you must excuse my lack of knowledge and for not grasping the specific terminology, yet.
I have the folowing model witch extends the basic user:
class UserProfile(models.Model):
user = models.OneToOneField(User)
birthday = models.DateField(blank=True)
about_me = models.TextField(blank=True,null=True)
avatar = models.ForeignKey(Picture,blank=True, null=True)
class Meta:
db_table = 'auth_user_profile'
I also have the following taxonomy model:
class TaxonomyGroup(models.Model):
related taxonomy items"""
name = models.CharField(max_length=25, db_index=True)
slug = AutoSlugField(populate_from='name', unique = True)
def __unicode__(self):
return u'%s' %self.name
class Meta:
db_table = 'taxonomies'
ordering = ['name']
class TaxonomyItem(models.Model):
taxonomy_group = models.ForeignKey(TaxonomyGroup, db_index=True)
name = models.CharField(max_length=55, db_index=True)
slug = AutoSlugField(populate_from='name', unique = True)
def __unicode__(self):
return u'%s' %self.name
class TaxonomyMap(models.Model):
taxonomy_group = models.ForeignKey(TaxonomyGroup, db_index=True)
taxonomy_item = models.ForeignKey(TaxonomyItem, db_index=True)
content_type = models.ForeignKey(ContentType, db_index=True)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey('content_type','object_id')
objects = TaxonomyManager()
class Meta:
db_table = 'term2object'
unique_together = ('taxonomy_item', 'content_type', 'object_id')

The way I see it, you want a many-to-many relationship between the taxonomy and user models, so you can add it to UserProfile model.
class UserProfile(models.Model):
user = models.OneToOneField(User)
birthday = models.DateField(blank=True)
about_me = models.TextField(blank=True,null=True)
avatar = models.ForeignKey(Picture,blank=True, null=True)
taxonomies = models.ManyToManyField(TaxonomyItem)
Then when you are adding terms for a specific user you'll do:
taxonomy = TaxonomyItem.objects.create(taxonomy_group=<some_group>, name=<some_name>,...)
profile = user.get_profile()
profile.taxonomies.add(taxonomy)
to retrieve you can do
profile.taxonomies.all()
