getting started - NameError: name 'location' is not defined

[Steven Kulesza]

 I am following along with the getting started guide and i am trying to sync my database after adding the haystack connections (http://django-oscar.readthedocs.org/en/latest/internals/getting_started.html#database) The location class is undefinded.

From settings.py where the error is located:

from oscar import OSCAR_MAIN_TEMPLATE_DIR

TEMPLATE_DIRS = (

    location('frobshop/templates'),

    OSCAR_MAIN_TEMPLATE_DIR,

)

The traceback log:

(oscar)Stevens-MacBook-Pro:frobshop steven$ python manage.py syncdb --traceback

Hi,

You may have to define a function to get the absolute path to a directory like this

BASE_DIR = os.path.dirname(os.path.dirname(__file__))

location = lambda x: os.path.join(

    os.path.realpath(BASE_DIR), x)

in your settings.py

I cannot find documentation for this, so your help will be much appreciated

Hi, 

I think you are referring to the documentation for the dev version.

Docs for the latest release version(0.7.x) can be found here.

http://django-oscar.readthedocs.org/en/releases-0.7/internals/getting_started.html

Lijo is correct. I've just added it to the docs:
