Custom Tag for multiple models

[madlit...@gmail.com]

I want to create a custom tag that includes a description field that will be applied to multiple models such as articles, projects, etc

I have read and understood this page (documentation) but it seems to document a custom tag setup for one model.

I get a error message when trying to add an eTag in the admin panel

FieldDoesNotExist at /admin/ecore/etag/add/

eTag has no field named u'content_type'

What I currently have is this:

from django.db import models

from taggit.models import TaggedItemBase

from django.contrib.contenttypes.generic import GenericForeignKey

# Create your models here.

class eTag(TaggedItemBase):

    content_object = GenericForeignKey()

    description_markdown = models.TextField(

        verbose_name = 'Description (Markdown)',

    )

And use it like so on an "article" model:

tags = TaggableManager(through=eTag) 

My problem may just be that I am using "GenericForeignKey()" but that is what the GenericTaggedItemBase() uses so I assume it is fine. 

How do I set up a custom tag model that allows a description that can be used for tagging multiple models?

Thanks, Eric

Also when I visit a view that has the model I get this error:

FieldError at /blog/2/markdown-test

Cannot resolve keyword u'content_object' into field. Choices are: description_markdown, id, tag

I just ended up just changing the model for TagBase as so:

class TagBase(models.Model):

    name = models.CharField(verbose_name=_('Name'), unique=True, max_length=100)

    slug = models.SlugField(verbose_name=_('Slug'), unique=True, max_length=100)

    description_markdown = models.TextField(

        verbose_name = 'Description (Markdown)',

        blank = True,

    )

Please post a better more elegant solution if you have any ideas.
