Python/Django TangoWithDjango Models and Databases

Question

I\'m currently following http://www.tangowithdjango.com and I\'m trying to populate an existing DB with populate_rango.py. When I create the new categories, I\'m tr

Answer 1

The following worked for me. I have no idea whether it will cause issues in later chapters, but it allowed the populate_rango.py script to run.

Changes to populate_rango.py

def populate():
    python_cat = add_cat("Python", views=128, likes=64)

    django_cat = add_cat("Django", views=64, likes=32) 

    frame_cat = add_cat("Other Frameworks", views=32, likes=16)

and

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

That resulted in a database IntegrityError so I edited the View fields in my Category and Page classes to ensure they aren't unique:

Changes to models.py

class Category(models.Model):
    views = models.IntegerField(default=0, unique=False)

class Page(models.Model):
    views = models.IntegerField(default=0, unique=False)

Finally, I deleted the database and ran

python manage.py syncdb

and

python populate_rango.py
