[Answer]-Django – Create Category Views doesn't create Column

1👍

Ah yes I overlooked a warning in the doc.

Warning Whenever you add to existing database models, you will have to
delete the database file and then re-sync the database by running
python manage.py syncb again. This is a drawback of Django 1.5.4, and
can be quite frustrating. If you however add a new model, you can
syncdb your database without having to delete and recreate it. You
must therefore bear this in mind when tweaking your database: new
models will be synchronised with syncdb – but changes to existing
models will not be. When adding a new model to your application’s
models.py file, you can simply run the following command to
synchronise the database with the command $ python manage.py syncdb.
When updating an existing model to your application’s models.py file,
you must perform the following steps. Delete the database. Recreate
the database with the command $ python manage.py syncdb. Populate the
new database with data. Deleting and recreating the database from
scratch is a frustrating process. A possible solution to this issue
could be to use a third party application like South to handle
database schema migrations (changes to your models). South is
currently in active development and is considered a standard solution
for Django schema migrations until this functionality becomes part of
the standard Django codebase. We don’t cover South here – but the
official South documentation provides a handy tutorial if you’re
interested. If you don’t want to use South, we discuss a technique in
Section 5.8 to speed up the updating process. You may have also
noticed that our Category model is currently lacking some fields that
we defined in Rango’s requirements. We will add these in later to
remind you of the updating process.

And it appears migrations in core will not be available until django 1.7.

I had incorrectly updated the populate script it should have looked like.

def add_page(cat, title, url, views=0):
    p = Page.objects.get_or_create(category=cat, title=title, url=url, views=views)[0]
    return p

def add_cat(name, views=0, likes=0):
    c = Category.objects.get_or_create(name=name, views=views, likes=likes)[0]
    return c
