Django_tagging (v0.3/pre): Configuration issue

Question

I am trying to use the django-tagging in one of my project and run into some errors.

I can play with tags in the shell but couldn't assign them from admin interface.

What I want to do is add "tag" functionality to a model and add/remove tags from Admin interface.

Why is it the "tags" are seen by shell and not by "admin" interface? What is going on?

Model.py:

import tagging

class Department(models.Model):
    tags = TagField()

Admin.py:

class DepartmentAdmin(admin.ModelAdmin):
    list_display = ('name', 'tags') --> works
....
    fields = ['name', 'tags'] --> throws error

Error

    OperationalError at /admin/department/1/
    (1054, "Unknown column 'schools_department.tags' in 'field list'")

I looked at the docs and couldn't find further information Useful Tips Overview Txt

Answer 1

The TagField requires an actual database column on your model; it uses this to cache the tags as entered. If you add a TagField to a model that already has a database table, you will need to add the column to the database table, just as with adding any other type of field. Either use a schema migration tool (like South or django-evolution) or run the appropriate SQL ALTER TABLE command manually.
